Monitoring is installed optionally (yet strongly recommended). ADCM monitoring is based on three services: Diamond, Graphite, and Grafana.
For online installation, you need a separate monitoring cluster. The steps for installing monitoring in this case are listed below. You can perform them both before and after the ADQM cluster installation, except the last step Integrate with ADQM cluster, that can be executed only when the ADQM cluster already exists.
