MON-1749 implements a feature where we users can configure CMO to disable the local Alertmanager. As a follow up, we docs for 4.9 need to be updated to reflect this option.

Example configuration for disabling Alertmanager:

apiVersion: v1
kind: ConfigMap
metadata:
  name: cluster-monitoring-config
  namespace: openshift-monitoring
data:
  config.yaml: |
    alertmanagerMain:
      enabled: false

 
A/C

• Document written that explains how to disable the local alertmanager.
