Showing data collected by remote health monitoring

As an administrator, you can review the metrics collected by Telemetry and the Insights Operator.

Showing data collected by Telemetry

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__="instance:etcd_object_counts:sum"} 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.

Showing data collected by the Insights Operator

You can review the data that is collected by the Insights Operator.

Prerequisites

  • Access to the cluster as a user with the cluster-admin role.

Procedure

  1. Find the name of the currently running Pod for the Insights Operator:

    $ INSIGHTS_OPERATOR_POD=$(oc get pods --namespace=openshift-insights -o custom-columns=:metadata.name --no-headers  --field-selector=status.phase=Running)

  2. Copy the recent data archives collected by the Insights Operator:

    $ oc cp openshift-insights/$INSIGHTS_OPERATOR_POD:/var/lib/insights-operator ./insights-data

The recent Insights Operator archives are now available in the insights-data directory.
