Creating a cluster monitoring configmap object

You can configure the core OpenShift Container Platform monitoring components by creating the cluster-monitoring-config configmap object in the openshift-monitoring project. The Cluster Monitoring Operator (CMO) then configures the core components of the monitoring stack.

Prerequisites

You must have access to the cluster as a user with the cluster-admin role.
OpenShift command-line interface is required. For more information, see Getting started with the OpenShift CLI.

Procedure

Check if the cluster-monitoring-config configmap object exists:

oc -n openshift-monitoring get configmap cluster-monitoring-config

If the configmap object does not exist:

Create the following YAML manifest. In this example, the file is called cluster-monitoring-config.yaml:
```
apiVersion: v1
kind: ConfigMap
metadata:
  name: cluster-monitoring-config
  namespace: openshift-monitoring
data:
  config.yaml: |
```
- Apply the configuration to create the configmap object:
```
oc apply -f cluster-monitoring-config.yaml
```
