You may need to go to Settings -> Variables -> bucket and hit Update for the correct buckets to load and for data to appear. This way if it is ever enabled, you will begin to immediately start to monitor it. Running a lottery? 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. Learn how to gather process metrics from each server running Couchbase. Create a Kubernetes service which targets the metrics endpoint on the Couchbase Clusters administrative console. 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. As a starting point, copy and paste the JSON provided in the exporter Grafana folder and then hit Load. Each one of these exporters will then each run an endpoint available for any Prometheus Server to scrape, once configured. This endpoint exists by default and does not require any configuration within the CouchbaseCluster resource to begin receiving metrics into Prometheus. In conjunction with the Couchbase Operator, the bearer token is supplied as a Kubernetes Secret. Tutorials are accurate at the time of writing but rely heavily on third party software. Prometheus can be used in conjunction with Couchbase server for several use cases such as monitoring, metering, and auto scaling. The Couchbase Metrics Service will define the set of pods we want to monitor and the port to scrape on each. When we configured Prometheus to run as a service, we specified the path of /etc/prometheus/prometheus.yml. These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. Which can be used to create dashboards like this. 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. Couchbase, Couchbase Lite and the Couchbase logo are registered trademarks of Couchbase, Inc. expose Couchbase metrics through the Kubernetes custom metrics API, list of the Couchbase metrics being exported, Label allows service to be selected by the Prometheus, Port to fetch metrics. Software Engineer based in the Manchester office, who has been working on the Couchbase Autonomous Operator for just over one and a half years. 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/. This is increasingly important as deployments scale to support a large numbers of connected mobile and edge components. Retailing on Black Friday? Then we can import one of our sample dashboards to visualise our data. Metrics can be refined to a per node and also a per bucket basis. 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 . # 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]. This way if it is ever enabled, you will begin to immediately start to monitor it. # both these values can be set to a minimum of 1s granularity if such precision is needed. 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 will be improved over time. I know that we can do it with kubernetes (https Hi all, Since now 5 months, we are using the couchbase chart to deploy our couchbase cluster. 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. This is the raw service that will be used by Prometheus for metric collection. 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. Metrics endpoint for Prometheus monitoring. 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. 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. It turns REST endpoint statistics from Couchbase Server like these, found in bucket info . 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! If you want a starting point, there are a few sample Grafana dashboards in the. Currently, the kube-prometheus project includes a folder called manifests that includes all the resources necessary to These include, but are not limited to, CPU and Memory usage, Ops per second, read and write rates, and queue sizes. This content covers the statistics and metrics collected and made available by Sync Gateway. The following example YAML is almost an exact replica of the Service Monitor YAML example in the earlier section, but with a few important differences. The ServiceMonitor resources are expected to be in the same namespace as Prometheus Operator. 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. In addition, you should ensure that your image source is trusted. The Prometheus Operator creates our Prometheus deployment which scrapes endpoints continuously for Prometheus metrics. Sync Gateway's statistics and metrics provide under-the-hood data on the performance, resource utilization and health of it nodes. 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. Edit the prometheus.yml file and add the following job. It's working pretty well but now, we would like to enable prometheus metrics. which contains the scrape_config job that includes a look-up for. Capella, Atlas, DynamoDB evaluated on 40 criteria. blakelead/couchbase_exporter Export metrics from Couchbase Server for Prometheus consumption Users starred: 25Users forked: 11Users watching: 25Updated at: 2020-04-13. In conjunction with the Couchbase Operator, the bearer token is supplied as a Kubernetes Secret. 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. However, the Couchbase Exporter repository contains a convenient list of the Couchbase metrics being exported. for monitoring Sync Gateway and we are building on that momentum adding it first to Kubernetes and OpenShift officially. TLS and mTLS are enabled by enabling these on the overall cluster. Enable the Collector receiver. Prometheus is the de facto metrics collection platform for use in Kubernetes environments. Jira Core help; Keyboard Shortcuts; About Jira; Jira Credits; Log In The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. $ 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 At time of writing the default password is prom-operator rather than admin as it is in kube-prometheus. Please use the form below to provide your feedback. This implies that there is no longer the need to have a separate exporter. At a component level, it comes together like this: Lets go into a little bit more detail about each component. While not. officially supported, there are also alternative runtime configurations to achieve the same goals. https://github.com/coreos/kube-prometheus, https://github.com/helm/charts/tree/master/stable/prometheus-operator, https://github.com/coreos/prometheus-operator. Create the following directory and file with the appropriate permissions. With the release of Autonomous Operator 2.0, a tutorial is provided in the docs. 3: couchbaseclusters.spec.autoscaleStabilizationPeriod: Setting this field to 0s serves two . We can now use commands similar to the ones found in the kube-prometheus documentation, to access Prometheus Server and Grafana. When we installed prometheus we configured an additional tool called promtool. I didnt see in documentation anything about it. You need to explicitly state what namespaces to poll for services. According to the latest blog post, youll need a Couchbase Exporter - https://blog.couchbase.com/couchbase-monitoring-integration-with-prometheus-and-grafana/. Monitors health metrics (estimated endurance, space capacity, critical warnings, temperature, etc.) 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. With Prometheus, multi-dimensional metric data can be collected from . Configure Prometheus. To complete the integration . For further information see the defined values.yaml in the Helm chart GitHub repository. The "Prometheus Operator" is the recommended project to refer to for deploying and managing Prometheus alongside of Couchbase. The Autonomous Operator does not create or manage resources for third-party software. 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. 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. Even if you are not currently using Analytics in your deployment, it is suggested to monitor it via Prometheus and the Couchbase Exporter. the information you submit in this form is recorded in our issue tracking system (JIRA), which is publicly available. This is a completely optional step and can be skipped if you do not wish to gather process metrics. Selects the metric services to monitor. . CB_PROCESS_EXPORTER_PORT - Optional, The port that process exporter is running on. The default password can be discovered in the prometheus-operator-grafana secret through base64 decoding. Only official Prometheus images provided by Couchbase are supported (with the exception of user-supplied images that specifically enable customized metrics). The ServiceMonitor is a Custom Resource created during installation of the Prometheus Operator that will direct Prometheus to monitor the dedicated metric service. 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. 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. 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. For any bugs, issues or feature requests, A special mention to Carlos Becker and the rest of the. Clone the kube-prometheus repository from GitHub, but do not create any manifests just yet. Because your feedback is valuable to us, 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. Configure Prometheus Alerts. Check that our ServiceMonitor and Service have been created. With this label added the Service Monitor will look something like the following. 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. Grafana is an open source data visualisation and alerting platform, mostly used to build incredibly comprehensive and user-customizable dashboards. When you expose important metrics through a client, Prometheus scrapes those metrics' current state in defined intervals. Once all pods are ready and running, in order to access Prometheus and Grafana, follow the relevant steps in the kube-prometheus documentation. Each copy of the exporter will then only pull per-node statistics from the node it is running on. I'm using couchbase 5.5.3 , and want to do the integration between CB and Prometheus. Defaults to 9200. These customizations are enabled by building your own custom version of the Couchbase Prometheus Exporter container image. I'm using couchbase 5.5.3 , and want to do the . The exporter supports certain user-configurable customizations to these defaults. It will then ask you to set a new password. A lightweight ability to graph statistics is present but it is more common to use Grafana. The Couchbase Exporter can act as a proxy to Process Exporter, retrieving . 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? Validate the target has been added and is being monitored. Whilst running within the Autonomous Operator, the Couchbase Exporter lives as a sidecar on each Kubernetes Pod, maximising local networking when it comes to specific node statistics and reducing the amount of intracluster traffic. The ServiceMonitor tells Prometheus to monitor the Service resource we just defined which then enables Prometheus to scrape for metrics provided by the Couchbase exporter. The Couchbase Prometheus Exporter currently supports the following customizations: Change the namespace, subsystem, name, and help text for each metric. For the exporter, download the source code from the couchbase/couchbase-exporter GitHub repo. As of Couchbase Server 7.0, a metric endpoint exists on each Couchbase Pod that is compatible with Prometheus metric collection. In order to properly take advantage of this feature, users must expose Couchbase metrics through the Kubernetes custom metrics API. Technical Overview. It is also possible to instead use the Prometheus Operator Helm chart which closely matches the kube-prometheus project. Tutorials are provided to demonstrate how a particular problem may be solved. 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. The Process Exporter is an agent that gathers process specific metrics and exposes them in a format which can be ingested by Prometheus. 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. If you have not configured Node Exporter, skip this step and proceed to the next step. 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. 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. Metrics can be refined to a per node and also a per bucket basis. The Autonomous Operator, with monitoring enabled, exposes the Couchbase Prometheus metrics on the sidecar containers running in each Couchbase Server pod. Its more of a protocol and toolkit to populate a time-series database and not a dashboard tool. To make sure the Helm chart will be deployed with the additional configuration, you can add the argument --dry-run to the command to view the intended configuration. 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. Here we will configure the Node Exporter job to gather system metrics from each of our nodes in each of the clusters. 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. 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. For instructions on how to create a custom metrics configuration and build it into a container image, refer to the couchbase-exporter README. Contributions certainly welcome! In Step 3 we demonstrated how to configure multiple clusters and configure the appropriate ini files. To import the dashboard of your choice, hover over to the plus icon on the left sidebar and select Import. The Couchbase Prometheus Exporter is an official Prometheus Exporter which supplies Couchbase Server metrics to Prometheus. Below is an example of Prometheus running in Docker. To use password authentication you will also need to add your authentication secret in the same namespace as the ServiceMonitor resource. The Couchbase-supplied Prometheus Exporter container image is only supported on Kubernetes platforms in conjunction with the Couchbase Autonomous Operator. Once Prometheus has been fully configured, anytime new nodes are added edit the /etc/prometheus/file_sd/couchbase.yml file with the new nodes. 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). The default location of the Prometheus Operator is the monitoring namespace. More on that toward the end. You can run Prometheus both locally and through Docker, much like the exporter. Using helm to deploy Couchbase with . 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. To run the exporter locally simply use the command. Try entering kv_ops into the metric search bar. As of time of writing one of the simplest ways to set up Prometheus and Grafana is to use the Prometheus Operator. . 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 Use the commands, to find the IPv4 Address of the Couchbase Exporter container and substitute this value for. The sidecar container requires access to the Couchbase cluster administrative credentials in order to login and perform collection. 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 Couchbase Forums. 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. The Autonomous Operator provides Prometheus integration for collecting and exposing Couchbase Server metrics via the Couchbase Prometheus Exporter. Metrics can be refined to a per node and also a per bucket basis. The Grafana dashboard allows visually monitoring key metrics and performance indicators for Couchbase Server clusters in one central place. Deploying the Couchbase Prometheus Exporter will allow us to start collecting Couchbase metrics. The new job prometheus should be listed with a status of "Up". To run the exporter locally simply use the command. It will then ask you to set a new password. run the Prometheus Operator. it will ask for a username and password, which is admin for both. The next step is to add Prometheus as a Data Source. 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. We use a YAML file to include in the values argument in helm install which will introduce additional configuration into the Helm Chart. It can be used to interact with prometheus, execute queries as well as validate configuration files. 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. Prometheus is configured through a single YAML file called prometheus.yml. Learn about Couchbase's ISV Program and how to join. When configuring Prometheus to monitor itself, a static config was used. You can validate your Prometheus config by issuing the following command: Open the Prometheus UI and validate the new job is listed and is "Up". If no results are returned, check Status Targets for any unhealthy endpoints and also check the Prometheus Operator logs for additional information. 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. 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 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. This corresponds to the. More on that toward the end. 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 linked tutorial covers the kube-prometheus GitHub project and its corresponding Helm chart. Couchbase Server. 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. Please adjust accordingly if changes have been made since as the repository is experimental and subject to change. Weve got you covered.
