第 2 章 Installing cluster logging

Ensure that openshift-operators-redhat is selected under Installed Namespace.

You must specify the openshift-operators-redhat namespace. The openshift-operators namespace might contain Community Operators, which are untrusted and could publish a metric with the same name as an OpenShift Container Platform metric, which would cause conflicts.

Select Enable operator recommended cluster monitoring on this namespace.

This option sets the openshift.io/cluster-monitoring: "true" label in the Namespace object. You must select this option to ensure that cluster monitoring scrapes the openshift-operators-redhat namespace.

Select an Approval Strategy.

Select Enable operator recommended cluster monitoring on this namespace.

This option sets the openshift.io/cluster-monitoring: "true" label in the Namespace object. You must select this option to ensure that cluster monitoring scrapes the openshift-logging namespace.

Select an Approval Strategy.

Ensure that Cluster Logging is listed in the openshift-logging project with a Status of Succeeded.

If the Operator does not appear as installed, to troubleshoot further:

On the ClusterLoggings page, click Create ClusterLogging.

You might have to refresh the page to load the data.

Select the openshift-logging project.

You should see several pods for cluster logging, Elasticsearch, Fluentd, and Kibana similar to the following list:
