This page describes how to enable monitoring system for collecting PipeCD’ metrics.

PipeCD comes with a monitoring system including Prometheus, Alertmanager, and Grafana. This page walks you through how to set up and use them.

Monitoring overview

Monitoring Architecture

Both the Control plane and piped agent have their own “admin servers” (the default port number is 9085), which are simple HTTP servers providing operational information such as health status, running version, go profile, and monitoring metrics.

The piped agent collects its metrics and periodically sends them to the Control plane. The Control plane then compacts its resource usage and cluster information with the metrics sent by the piped agent and re-publishes them via its admin server. When the PipeCD monitoring feature is turned on, Prometheus, Alertmanager, and Grafana are deployed with the Control plane, and Prometheus retrieves metrics information from the Control plane’s admin server.

Developers managing the piped agent can also get metrics directly from the piped agent and monitor them with their custom monitoring service.

Enable monitoring system

To enable monitoring system for PipeCD, you first need to set the following value to helm install when installing.

--set monitoring.enabled=true


If you’ve already enabled monitoring system in the previous section, you can access Grafana using port forwarding:

kubectl port-forward -n {NAMESPACE} svc/{PIPECD_RELEASE_NAME}-grafana 3000:80

Control Plane dashboards

There are three dashboards related to Control Plane:

  • Overview - usage stats of PipeCD
  • Incoming Requests - gRPC and HTTP requests stats to check for any negative impact on users
  • Go - processes stats of PipeCD components

Piped dashboards

Visualize the metrics of Piped registered in the Control plane.

  • Overview - usage stats of piped agents
  • Process - resource usage of piped agent
  • Go - processes stats of piped agents.

Cluster dashboards

Because cluster dashboards tracks cluster-wide metrics, defaults to disable. You can enable it with:


There are three dashboards that track metrics for:

  • Node - nodes stats within the Kubernetes cluster where PipeCD runs on
  • Pod - stats for pods that make PipeCD up
  • Prometheus - stats for Prometheus itself

Alert notifications

If you want to send alert notifications to external services like Slack, you need to set an alertmanager configuration file.

For example, let’s say you use Slack as a receiver. Create values.yaml and put the following configuration to there.

        slack_api_url: {YOUR_WEBHOOK_URL}
        receiver: slack-notifications
        - name: slack-notifications
            - channel: '#your-channel'

And give it to the helm install command when installing.


See here for more details on AlertManager’s configuration.

Piped agent metrics

Metric Type Description
cloudprovider_kubernetes_tool_calls_total counter Number of calls made to run the tool like kubectl, kustomize.
deployment_status gauge The current status of deployment. 1 for current status, 0 for others.
livestatestore_kubernetes_api_requests_total counter Number of requests sent to kubernetes api server.
livestatestore_kubernetes_resource_events_total counter Number of resource events received from kubernetes server.
plan_preview_command_handled_total counter Total number of plan-preview commands handled at piped.
plan_preview_command_handling_seconds histogram Histogram of handling seconds of plan-preview commands.
plan_preview_command_received_total counter Total number of plan-preview commands received at piped.

Control plane metrics

All Piped’s metrics are sent to the control plane so that they are also available on the control plane’s metrics server.

Metric Type Description
cache_get_operation_total counter Number of cache get operation while processing.
grpcapi_create_deployment_total counter Number of successful CreateDeployment RPC with project label.
http_request_duration_milliseconds histogram Histogram of request latencies in milliseconds.
http_requests_total counter Total number of HTTP requests.
insight_application_total gauge Number of applications currently controlled by control plane.
