However this may not always be up to date whereas the git repository will be. Granting these credentials to arbitrary code is potentially harmful. One you may run into is the ServiceMonitor reporting problems due to your bearer token Secret not being created. The Couchbase Metrics Service will define the set of pods we want to monitor and the port to scrape on each. It's working pretty well but now, we would like to enable prometheus metrics. The Process Exporter is an agent that gathers process specific metrics and exposes them in a format which can be ingested by Prometheus. Capella, Atlas, DynamoDB evaluated on 40 criteria. The Couchbase Exporter will be used as a proxy to Process Exporter, the Couchbase Exporter will add the labels of cluster="", node="" to the metrics returned by Process Exporter, this way the Process Exporter metrics can be associated with Couchbase metrics. What are the types of metrics in Prometheus? These metrics are different than the ones that have been previously gathered and should be queried at an independent interval as the values returned are point in time without a history. The Prometheus Operator creates our Prometheus deployment which scrapes endpoints continuously for Prometheus metrics. As a starting point, copy and paste the JSON provided in the exporter Grafana folder and then hit Load. The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. Check that our ServiceMonitor and Service have been created. By default Node Exporter runs on port 9100, this . The next step is to add Prometheus as a Data Source. The Couchbase Exporter will be used as a proxy to Node Exporter, the Couchbase Exporter will add the labels of cluster="", node="" to the metrics returned by Node Exporter, this way the Node Exporter metrics can be associated with Couchbase metrics. It is also possible to instead use the Prometheus Operator Helm chart which closely matches the kube-prometheus project. As of Couchbase Server 7.0, a metric endpoint exists on each Couchbase Pod that is compatible with Prometheus metric collection. Couchbase is JSON database that excels in high volume transactions. Source: https://prometheus.io/docs/prometheus/latest/installation/#using-docker. Give feedback to Atlassian; Help. We're here to help. In order for our Prometheus deployment to recognize and scrape Couchbase endpoints, we need to create a Couchbase specific service monitor, and a Couchbase metrics specific service. Create a Kubernetes service which targets the metrics endpoint on the Couchbase Clusters administrative console. This guide walks through recommended procedures for enabling and configuring Prometheus monitoring of the Couchbase Autonomous Operator. These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. Enable the Collector receiver. The exporter is compatible with Couchbase Server versions 5.5.x onwards, but we would recommend to use version 6.0.4 or newer due to the upcoming EOL of 5.x. If you do not want slow queries to be returned from the /metrics/queries endpoint, you can add the following block to the job: Even if you are not currently using Eventing in your deployment, it is suggested to monitor it via Prometheus and the Couchbase Exporter. By default, the exporter collects all metrics from Couchbase Server, with each metric having a default name and default metadata associated with it. These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. This endpoint exists by default and does not require any configuration within the CouchbaseCluster resource to begin receiving metrics into Prometheus. . Prometheus ingests stats via scrape jobs, we will configure 10 different scrape jobs for the following: You do not have to restart Prometheus after adding each job listed below. The Autonomous Operator provides Prometheus integration for collecting and exposing Couchbase Server metrics via the Couchbase Prometheus Exporter. it will ask for a username and password, which is admin for both. With the release of Autonomous Operator 2.0, a tutorial is provided in the docs. If you have not configured Process Exporter, skip this step and proceed to the next step. Therefore, the only setup required is to properly direct Prometheus to the Couchbase metric endpoint that requires the creation of a dedicated metric service along with a ServiceMonitor resource as outlined below. The Prometheus Operator has a labelSelector defined looking for the label release: prometheus-operator so we need to add this to our Couchbase Service Monitor. The Grafana dashboard allows visually monitoring key metrics and performance indicators for Couchbase Server clusters in one central place. I'm using couchbase 5.5.3 , and want to do the . The ServiceMonitor resources are expected to be in the same namespace as Prometheus Operator. To import the dashboard of your choice, hover over to the plus icon on the left sidebar and select Import. It does this while also offering options for network security with TLS and mTLS and protection of any potential sensitive data from the exporter via a bearer token. If pulling directly from the the Red Hat Container Catalog, then the path will be something similar to registry.connect.redhat.com/couchbase/exporter:1.0.6 (you can refer to the catalog for the most recent images). You can track the status of your feedback using the ticket number displayed in the dialog once you submit the form. marwanb February 19, 2019, 12:23pm #1. This requires that every node in the cluster is configured with a public/private key pair and that the system variables are set in the exporter configuration. You can run Prometheus both locally and through Docker, much like the exporter. # both these values can be set to a minimum of 1s granularity if such precision is needed scrape_interval: 60s scrape_timeout: 55s, static_configs: targets: [localhost:9091]. However the Prometheus Operator Helm chart deployment requires an extra bit of configuration to the Service Monitor for the Service Monitor to show up in Prometheus. The default location of the Prometheus Operator is the monitoring namespace. Follow the instructions found in the README for any more advanced configurations.

An example of a bearer token as a Secret: In standalone, supply the location of a token file using the flag token, and similar for any PKI resources using the flags key, cert and ca, where key refers to the private key to be used, cert the certificate chain, and ca the top-level certificate authority. If you want a starting point, there are a few sample Grafana dashboards in the couchbase-exporter GitHub repo which will be improved over time. Even if you are not currently using FTS in your deployment, it is suggested to monitor it via Prometheus and the Couchbase Exporter. If not, edit the file accordingly if needed so that the scrape_config job includes the correct IP address for the exporter. Prometheus is the de facto metrics collection platform for use in Kubernetes environments. However, the Couchbase Exporter repository contains a convenient list of the Couchbase metrics being exported. Try entering kv_ops into the metric search bar. Later on in this tutorial we'll be passing Couchbase metrics to the Kubernetes custom metrics API, which will allow them to be monitored by the HPA. The Couchbase Exporter exposes two additional endpoints /metrics/node_exporter and /metrics/process_exporter, these endpoints act as a proxy calling the Node / Process Exporter directly, but before the stats are returned, the cluster and node name labels are added to the metrics they return. Selects the metric services to monitor. Here we will configure the Process Exporter to gather system metrics from each of our nodes in each of the clusters. The restarts and validation are simply added for verification purposes. We can now use commands similar to the ones found in the kube-prometheus documentation, to access Prometheus Server and Grafana. Couchbase Server currently has a plethora of stats from data access throughput in KV and query to system resources like disk IO and CPU to newer services like eventing. For instructions on how to create a custom metrics configuration and build it into a container image, refer to the couchbase-exporter README. on the TOTVS Labs couchbase exporter project as well as the Leansys couchbase exporter for providing the baseline inspiration for this project! https://prometheus.io/docs/prometheus/latest/installation/#using-docker, Run prometheus and the exporter which hosts metrics at, and the exporter URL should appear on the list of Prometheus targets at, If you are running both the exporter and Prometheus in Docker, the setup is slightly more complicated. Because your feedback is valuable to us, This is useful when using issuing PromQL statements or querying in Grafana which we will cover later. If you are running both the exporter and Prometheus in Docker, the setup is slightly more complicated. When configuring Prometheus to monitor itself, a static config was used. It does this while also offering options for network security with TLS and mTLS and protection of any potential sensitive data from the exporter via a bearer token. which contains the scrape_config job that includes a look-up for. using the nvme CLI tool.. This is the raw service that will be used by Prometheus for metric collection. 3: couchbaseclusters.spec.autoscaleStabilizationPeriod: Setting this field to 0s serves two . If, for any reason, this is undesirable, or simply not feasible, the Prometheus Operator deployment resource can be modified to select ServiceMonitor resources from a different namespace by modifying the serviceMonitorNamespaceSelector as specified in the "Prometheus Custom Resource Definition". To run the exporter locally simply use the command. We will be creating these manifests in a later step. Configure Prometheus. Copy this YAML into a file named couchbase-serviceMonitor.yaml for example, and save it in the manifests directory. The OpenTelemetry repo's readme provides additional details about Prometheus receiver configuration.. Validate the target has been added and is being monitored. Technical Overview Prometheus scrape targets must be manually created by the user. It can be used to interact with prometheus, execute queries as well as validate configuration files. This tutorial works on the basis that the manifests which bring up the relevant resources for Prometheus Operator are still located in the folder manifests. Configure Prometheus Alerts. Learn how to configure Prometheus to monitor itself, discover new nodes to monitor, and configure various exporter jobs; See detailed examples of exporter configuration at the node, process, and bucket level as well as exporter config for each Couchbase Service In this post, we discuss how you can use Prometheus, an open source monitoring and alerting platform for monitoring your Sync Gateway nodes and Grafana for . The Couchbase Mobile 2.5 release introduced extensive stats reporting capabilities on the Sync Gateway.The stats provide key insights into the health of your Couchbase Mobile deployment and constitues an integral part of any deployment. Once configured, active metrics can be collected from each Couchbase Server pod on port 9091. Once Prometheus has been fully configured, anytime new nodes are added edit the /etc/prometheus/file_sd/couchbase.yml file with the new nodes. Java Spring Boot,java,spring,spring-boot,prometheus,code-metrics,Java,Spring,Spring Boot,Prometheus,Code Metrics,Spring BootPrometheus DockerMac pom.xml <dependency> <groupId>org.springframework.boot . Installation. Overview. Depending on where you are running Prometheus, the HTTP URL address will be localhost or the address where youve hosted or exposed it, with the port 9090. : 2: The port may be a literal port number as defined in the couchbase-metrics service, or may reference the port in the same . Enable and disable whether a metric is exported to Prometheus. While not officially supported yet, as mentioned its certainly possible to run this as a process or as a Docker container alongside your Couchbase Server nodes. As a starting point, JSON provided in the exporter Grafana folder, The exporter supports communication over TLS and mTLS as well as restricting who sees the metrics information through usage of a bearer token flag. To use password authentication you will also need to add your authentication secret in the same namespace as the ServiceMonitor resource. Prometheus metrics collection is enabled in the CouchbaseCluster resource. The configuration allows you to specify a Couchbase-provided container image that contains the Prometheus Exporter. Alternatively you can pull the official Dockerhub image found here. the information you submit in this form is recorded in our issue tracking system (JIRA), which is publicly available. Prometheus is the de facto metrics collection platform for use in Kubernetes environments. Then we can import one of our sample dashboards to visualise our data. To install and set up Grafana, choose your relevant platform and follow the installation. Learn about Couchbase's ISV Program and how to join. The Autonomous Operator supports auto-scaling Couchbase clusters. Create the following directory and file with the appropriate permissions. To get everything working, you will need to set up the four main components in this monitoring pipeline, Couchbase Server itself, the Couchbase Exporter, Prometheus and Grafana. Dashboards can be pretty specific to what you as a user care about, so youll want to customise accordingly. According to the latest blog post, youll need a Couchbase Exporter - https://blog.couchbase.com/couchbase-monitoring-integration-with-prometheus-and-grafana/. # if the stat name starts with data_* strip off index_, # if the stat name starts with index_* strip off index_, # if the stat name starts with query_* strip off index_, # if the stat name starts with xdcr_* strip off index_, # if the stat name starts with system_* strip off index_, # if the stat name starts with eventing_* strip off index_, # add eventing_ to the start of every stat, # if the stat name starts with analytics_* strip off index_, # add analytics_ to the start of every stat, # if the stat name starts with fts_* strip off index_, https://github.com/couchbaselabs/cbprometheus_python/blob/master/prometheus/prometheus.yml, Learn how to configure Prometheus to monitor itself, discover new nodes to monitor, and configure various exporter jobs, See detailed examples of exporter configuration at the node, process, and bucket level as well as exporter config for each Couchbase Service. The new job prometheus should be listed with a status of "Up". Follow the specific commands given in the kube-prometheus documentation to bring up our created resources along with the other provided default manifests. With the flag -d if you wish to run the image detached in the background. TLS and mTLS are enabled by enabling these on the overall cluster. Sync Gateway's statistics and metrics provide under-the-hood data on the performance, resource utilization and health of it nodes. . Save as couchbase-prometheus-monitor.yaml after making any necessary modifications as described below: Commit the service monitor configuration: A quick way to check that metrics are being collected is to forward the Prometheus service port to your local machine and query the dashboard for Couchbase related metrics. You need to explicitly state what namespaces to poll for services. Edit the prometheus.yml file and add the following under the scrape_configs: block. This takes an existing Couchbase stat as exposed by the exporter and renames it. The exporter supports communication over TLS and mTLS as well as restricting who sees the metrics information through usage of a bearer token flag. Edit the prometheus.yml file and add the following job. At its essence, the Couchbase Exporter provides the first building block in this workflow by providing Prometheus endpoints that are pulled at an interval defined by Prometheus server. To run the exporter locally simply use the command. The exporter supports certain user-configurable customizations to these defaults. Defaults to 9200. To import the dashboard of your choice, hover over to the plus icon on the left sidebar and select Import. As well as providing a degree of redundancy; if one pod goes down, overall cluster statistics and statistics on the active pods persist. Contributions certainly welcome! Additionally, for this job we are leveraging a metric_renamer. However this may not always be up to date whereas the git repository will be. Prometheus has four primary metric types to query for via PromQL: counters, gauges, histograms, and summaries. Metrics can be refined to a per node and also a per bucket basis. Even if you are not currently using Analytics in your deployment, it is suggested to monitor it via Prometheus and the Couchbase Exporter. Below is an example of Prometheus running in Docker. The following is an example ServiceMonitor configuration. Deploying the Couchbase Prometheus Exporter will allow us to start collecting Couchbase metrics. which is where the exporter metrics should be served if running locally. Download and run Prometheus locally, then use our provided prometheus.yml which contains the scrape_config job that includes a look-up for localhost:9091 which is where the exporter metrics should be served if running locally. Use the commands docker network list and docker network inspect to find the IPv4 Address of the Couchbase Exporter container and substitute this value for localhost in the list of scrape targets. Our task is then to get Prometheus to discover and scrape these endpoints in order to monitor the overall cluster through the Prometheus UI and with custom Grafana dashboards. An important distinction however is that the Grafana default password will be different. Metrics can be refined to a per node and also a per bucket basis. https://github.com/coreos/kube-prometheus, https://github.com/helm/charts/tree/master/stable/prometheus-operator, https://github.com/coreos/prometheus-operator. At its essence, the Couchbase Exporter provides the first building block in this workflow by providing Prometheus endpoints that are pulled at an interval defined by Prometheus server. Because of the Open Source nature of Prometheus and the exporters that existed before, we want to actively encourage community contributions to the project. The linked tutorial covers the kube-prometheus GitHub project and its corresponding Helm chart. The Couchbase Prometheus Exporter currently supports the following customizations: Change the namespace, subsystem, name, and help text for each metric. The Autonomous Operator injects the image as a "sidecar" container in each Couchbase Server pod. Learn how to gather process metrics from each server running Couchbase. This does mean that each node running Couchbase has to run a copy of the exporter in order for these per-node statistics to be available. The OpenTelemetry Collector, when configured with a Prometheus receiver, provides an integration with PHP-FPM to scrape Prometheus metrics. Requirements The Couchbase-supplied Prometheus Exporter container image is only supported on Kubernetes platforms in conjunction with the Couchbase Autonomous Operator. For the exporter, download the source code from the couchbase/couchbase-exporter GitHub repo. which will be improved over time. Tutorials are provided to demonstrate how a particular problem may be solved. Check your inbox or spam folder to confirm your subscription. This blog post will walk through how to get the exporter set up along with Prometheus and Grafana, as well as giving a brief overview of how to monitor a. Then we can import one of our sample dashboards to visualise our data. This ensures for this job, every stat that is ingested is prefixed with data_. This way if it is ever enabled, you will begin to immediately start to monitor it. The nodes will automatically be picked up by Prometheus and monitored without a restart of Prometheus being required. If you wish to create a Kubernetes secret with a bearer token, simply edit and create the following definition: The stringData field allows you to put a non-base64 encoded string directly into the Secret, and Kubernetes will then encode the string for you when the Secret is created or updated. These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. Get certified and bring your Couchbase knowledge to the database market. Use of third party software is not supported by Couchbase. Use the commands, to find the IPv4 Address of the Couchbase Exporter container and substitute this value for. If you want a starting point, there are a few sample Grafana dashboards in the. . $ prometheus-couchbase-exporter -c <couchbase host:port> -p <port to listen> Docker instructions: Environment variables In order to configure the Couchbase exporter for use with other than default settings you can pass in the following environment variables: Environment variables In Step 3 we demonstrated how to configure multiple clusters and configure the appropriate ini files. From there, the metrics are processed and exported to Lightstep Observability. Metrics can be refined to a per node and also a per bucket basis. One of the aims of this project is to provide an official Prometheus Exporter for Couchbase. blakelead/couchbase_exporter Export metrics from Couchbase Server for Prometheus consumption Users starred: 25Users forked: 11Users watching: 25Updated at: 2020-04-13. The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. An example of a bearer token as a Secret: For the exporter, download the source code from the, //github.com/couchbase/couchbase-exporter.git, Alternatively you can pull the official Dockerhub image found. A special mention to Carlos Becker and the rest of the contributors on the TOTVS Labs couchbase exporter project as well as the Leansys couchbase exporter for providing the baseline inspiration for this project! These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. When Couchbase Cluster has TLS enabled, port, Prometheus Operator can authenticate to Couchbase using the same username and password as the Couchbase Operator as long as the authentication Secret also exists in the same namespace as the. While not yet officially supported, there are also alternative runtime configurations to achieve the same goals. When we configured Prometheus to run as a service, we specified the path of /etc/prometheus/prometheus.yml. With the release of Autonomous Operator 2.0, we support Prometheus stats in conjunction with the Operator managed deployments. Now all we need to do is make sure our Couchbase service and Service Monitor are deployed for the Prometheus Operator to recognize. The Couchbase Exporter can act as a proxy to Process Exporter, retrieving . Dashboards can be pretty specific to what you as a user care about, so youll want to customise accordingly. for monitoring Sync Gateway and we are building on that momentum adding it first to Kubernetes and OpenShift officially. If the status shows as "Unknown" give it a few seconds and refresh. Its more of a protocol and toolkit to populate a time-series database and not a dashboard tool. Is there any implementation done to expose metrics using endpoint ? Weve got you covered. This content covers the statistics and metrics collected and made available by Sync Gateway. Please use the form below to provide your feedback. You can run Prometheus both locally and through Docker, much like the exporter. For further information see the defined values.yaml in the Helm chart GitHub repository. In order to visualise the data collected by Prometheus we can use the incredibly flexible Grafana which consumes the Prometheus API to create customizable dashboards. However, since Pod resources are immutable, enabling or disabling metric collection will require a rolling upgrade of the cluster. The Autonomous Operator does not create or manage resources for third-party software. With the release of Autonomous Operator 2.0, we support Prometheus stats in conjunction with the Operator managed deployments. Which can be used to create dashboards like this. You can optionally specify a Kubernetes Secret that contains a bearer token value that clients will need to use to gain access to the Prometheus metrics. In addition, you should ensure that your image source is trusted. I followed the above link and get the below error: ERRO[0002] failed to scrape buckets error="failed to get buckets: Powered by Discourse, best viewed with JavaScript enabled, Metrics endpoint for Prometheus monitoring, https://blog.couchbase.com/couchbase-monitoring-integration-with-prometheus-and-grafana/. In conjunction with the Couchbase Operator, the bearer token is supplied as a Kubernetes Secret. After changing the file, the prometheus service will need to be restarted to pickup the changes. Couchbase Server already exposes metrics in a JSON format through a rest interface so the exporters job is to take those metrics and output them in a Prometheus-friendly format. Contributions certainly welcome! This implies that there is no longer the need to have a separate exporter. Components such as Prometheus, Alertmanager, Node Exporter and Grafana should then startup and we can confirm this by inspecting the pods in the namespace monitoring. 2022 Couchbase, Inc. Couchbase, Couchbase Lite and the Couchbase logo are registered trademarks of Couchbase, Inc. Keep this port as its default value of 9091 as this is the default port the Couchbase Exporter will be writing to. # How long until a scrape request times out. At time of writing the default password is prom-operator rather than admin as it is in kube-prometheus. You can track the status of your feedback using the ticket number displayed in the dialog once you submit the form. You may need to go to Settings -> Variables -> bucket and hit Update for the correct buckets to load and for data to appear. TLS and mTLS are enabled by enabling these on the. 1: You may wish to include our Couchbase ServiceMonitor in the monitoring namespace along with the other ServiceMonitors included in the provided kube-prometheus manifests. These metric types fulfill the needs or requirements for most use cases, and are found in Prometheus' official client libraries: Go, Java, Ruby, and Python. Using helm to deploy Couchbase with . While not. Because your feedback is valuable to us, In addition, Prometheus allows configuration of alerting rules that would send notifications to a user or mailing list about certain conditions for when a given metric falls or exceeds a certain threshold. Prometheus is configured through a single YAML file called prometheus.yml. Metrics can be refined to a per node and also a per bucket basis. With Prometheus, multi-dimensional metric data can be collected from . Software Engineer based in the Manchester office, who has been working on the Couchbase Autonomous Operator for just over one and a half years. The "Prometheus Operator" is the recommended project to refer to for deploying and managing Prometheus alongside of Couchbase. For any bugs, issues or feature requests, please use our JIRA. Prometheus is a leading open-source monitoring solution which has become the industry standard for metrics collection and alert generation on cloud platforms. This is increasingly important as deployments scale to support a large numbers of connected mobile and edge components. Once this YAML file is created and saved, we can then deploy the Prometheus Operator with Helm using the following command. Prometheus server in CMOS stack helps to scrape Couchbase Server metrics and generate alerts on them. This way if it is ever enabled, you will begin to immediately start to monitor it. The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. I'm using couchbase 5.5.3 , and want to do the integration between CB and Prometheus. If no results are returned, check Status Targets for any unhealthy endpoints and also check the Prometheus Operator logs for additional information. When you expose important metrics through a client, Prometheus scrapes those metrics' current state in defined intervals. Please use the form below to provide your feedback. Each one of these exporters will then each run an endpoint available for any Prometheus Server to scrape, once configured. We use a YAML file to include in the values argument in helm install which will introduce additional configuration into the Helm Chart. Prometheus can be used in conjunction with Couchbase server for several use cases such as monitoring, metering, and auto scaling. Here we will configure the Node Exporter job to gather system metrics from each of our nodes in each of the clusters. Couchbase Forums. To get everything working, you will need to set up the four main components in this monitoring pipeline, Couchbase Server itself, the Couchbase Exporter, Prometheus and Grafana. If image pull secrets are required to access the image, they are inherited from the Couchbase Server pod and can be set explicitly with the couchbaseclusters.spec.servers.pod.spec.imagePullSecrets field or implicitly with a service account specified with the couchbaseclusters.spec.servers.pod.spec.serviceAccountName field. With the release of Autonomous Operator 2.0, Extending Maintenance for Couchbase Server 5.x, VPC Peering with Capella and GCP A Walkthrough, Developer Velocity on the Stack Overflow Podcast, Advanced Geospatial Support added to Search Service, Why Choose a NoSQL Database? A lightweight ability to graph statistics is present but it is more common to use Grafana. Only one service is necessary for each Couchbase cluster since Couchbase aggregates statistics across all of the Pods. If we were to just run with this ServiceMonitor and without any defined Service we would see on our Prometheus targets page a section for Couchbase endpoints but none showing. Only official Prometheus images provided by Couchbase are supported (with the exception of user-supplied images that specifically enable customized metrics). Currently, the kube-prometheus project includes a folder called manifests that includes all the resources necessary to If not, edit the file accordingly if needed so that the scrape_config job includes the correct IP address for the exporter. It will then ask you to set a new password. Make sure you have a Kubernetes cluster running the Autonomous Operator with monitoring enabled and follow the Prerequisites section in the kube-prometheus documentation. Save the following configuration as a file named couchbase-prometheus-service.yaml and make any modifications as described: Create the service resource in the same namespace as the CouchbaseCluster you wish to monitor, in this example we assume default: Now create a ServiceMonitor resource to direct Prometheus to monitor this metric service. More on that toward the end. 2022 Couchbase, Inc. Couchbase, Couchbase Lite and the Couchbase logo are registered trademarks of Couchbase, Inc. Couchbase Server currently has a plethora of stats from data access throughput in KV and query to system resources like disk IO and CPU to newer services like eventing. To check that all is working correctly with the Prometheus Operator deployment, run the following command to view the logs: Any potential issues that may arise should be fairly straight forward to debug and understand. The Couchbase Exporter can act as a proxy to Node Exporter, retrieving Node Exporter and adding labels with Couchbase Server information to the Node Exporter Metrics. As of time of writing one of the simplest ways to set up Prometheus and Grafana is to use the Prometheus Operator. Run prometheus and the exporter which hosts metrics at localhost:9091/metrics, and the exporter URL should appear on the list of Prometheus targets at localhost:9090/targets and report as UP. Clone the kube-prometheus repository from GitHub, but do not create any manifests just yet. Notice in this instance there are 2 targets configured, one on port 5000 and one on 5001 this is to illustrate monitoring multiple clusters. Once all pods are ready and running, in order to access Prometheus and Grafana, follow the relevant steps in the kube-prometheus documentation. Stats are exported in Prometheus-compatible format through the metrics endpoint. Jira Core help; Keyboard Shortcuts; About Jira; Jira Credits; Log In 2022 Couchbase, Inc. Couchbase, Couchbase Lite and the Couchbase logo are registered trademarks of Couchbase,Inc. # How frequently to scrape targets by default. In conjunction with the Couchbase Operator, the bearer token is supplied as a Kubernetes Secret. Is there any implementation done to expose metrics using endpoint ? Learn how to create and configure rules to send effective alerts; Work with our example rules to get an understanding of how rules work, then write rules that are custom-tailored to your application; See your rules in action with the Prometheus UI Prometheus can be used in conjunction with Couchbase server for several use cases such as monitoring, metering, and auto scaling. Retailing on Black Friday? The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. Give feedback to Atlassian; Help. These differences exist due to the way that the Helm Chart structure has been defined. For examples of this tutorial we have just left it in the default namespace for ease of use. Once you have your Couchbase Cluster running, fetch and install the Prometheus Operator stack. Im using couchbase 5.5.3 , and want to do the integration between CB and Prometheus. The ServiceMonitor is a Custom Resource created during installation of the Prometheus Operator that will direct Prometheus to monitor the dedicated metric service. The sidecar container requires access to the Couchbase cluster administrative credentials in order to login and perform collection. A full prometheus.yml file can be found at https://github.com/couchbaselabs/cbprometheus_python/blob/master/prometheus/prometheus.yml. The exporter is compatible with Couchbase Server versions 5.5.x onwards, but we would recommend to use version 6.0.4 or newer due to the upcoming EOL of 5.x. I didnt see in documentation anything about it. # both these values can be set to a minimum of 1s granularity if such precision is needed. To run through Docker, make sure your prometheus.yml file is correct, and then run one of the following commands: With the flag -d if you wish to run the image detached in the background. Compare Couchbase pricing or ask a question. For the remaining jobs, a file_sd_config will be used. At a component level, it comes together like this: Lets go into a little bit more detail about each component. Here we want to match the namespace of the Couchbase Metrics. Prometheus metrics collection is enabled in the CouchbaseCluster resource. The Collector uses the Prometheus Receiver to fetch metrics from the PHP-FPM Exporter endpoint. Copy this YAML into a file named, for example, couchbase-service.yaml and make sure it is placed in the manifests directory. Kubernetes. Couchbase Server. officially supported, there are also alternative runtime configurations to achieve the same goals. In this instance it defines Sync Gateway's metricsInterface as being accessible on sync_gateway:4986/_metrics . This job will execute cbstats against each node in the cluster. It's working pretty well but now, we would like to enable prometheus metrics. Prometheus is an Open Source systems monitoring and alerting toolkit, and the 2nd project to join the CNCF after Kubernetes, so it is a natural fit for Kubernetes environments and widely-adopted. Technical Overview. The "Prometheus Operator" is the recommended project to refer to for deploying and managing Prometheus alongside of Couchbase. Some metric names are further explained in the Couchbase Server documentation: You might find the following resources helpful when setting up your Prometheus environment: 2022 Couchbase, Inc.
