An administrator might need to review the metrics that Telemetry collects.

Showing data collected from the cluster

You can see the cluster and components time series data captured by Telemetry.

Prerequisites
  • Install the OpenShift Command-line Interface (CLI), commonly known as oc.

  • You must log in to the cluster with a user that has the cluster-admin role.

Procedure
  1. Find the URL for the Prometheus service that runs in the OpenShift Container Platform cluster:

    $ oc get route prometheus-k8s -n openshift-monitoring -o jsonpath="{.spec.host}"
  2. Navigate to the URL.

  3. Enter this query in the Expression input box and press Execute:

    {__name__="up"} or {__name__="cluster_version"} or {__name__="cluster_version_available_updates"} or {__name__="cluster_operator_up"} or {__name__="cluster_operator_conditions"} or {__name__="cluster_version_payload"} or {__name__="cluster_version_payload_errors"} or {__name__="etcd_object_counts"} or {__name__="ALERTS",alertstate="firing"} or {__name__="code:apiserver_request_count:rate:sum"} or {__name__="kube_pod_status_ready:etcd:sum"} or {__name__="kube_pod_status_ready:image_registry:sum"} or {__name__="cluster:capacity_cpu_cores:sum"} or {__name__="cluster:capacity_memory_bytes:sum"} or {__name__="cluster:cpu_usage_cores:sum"} or {__name__="cluster:memory_usage_bytes:sum"} or {__name__="openshift:cpu_usage_cores:sum"} or {__name__="openshift:memory_usage_bytes:sum"} or {__name__="cluster:node_instance_type_count:sum"}

    This query replicates the request that Telemetry makes against a running OpenShift Container Platform cluster’s Prometheus service and returns the full set of time series captured by Telemetry.
