      We will add a section for "systemd" Collector in "nodeExporter.collectors" section in CMO configmap. 

      It has a boolean field "enabled", the default value is false.

      apiVersion: v1
kind: ConfigMap
metadata: 
  name: cluster-monitoring-config
  namespace: openshift-monitoring
data: 

  config.yaml: |

    nodeExporter: 
      collectors: 
        # enablea collector which is disabled by default
        systemd: 
          enabled: true

       

      To avoid too many metrics are scraped from systemd units, the collector should collect metrics on selected units only. We put regex patterns of the units to collect in the list `collectors.systemd.units`.
