Move or Add a Monitoring or Backup Agent

On this page

Overview

When you deploy MongoDB as a replica set or sharded cluster on a group of servers, Ops Manager selects a server to run the Monitoring Agent. If you enable Ops Manager Backup, Ops Manager also selects a server to run the Backup Agent.

You can move the Monitoring and Backup Agents to different servers in the deployment. You might choose to do this, for example, if you are terminating a server.

You also can add additional instances of each agent as hot standbys for high availability. If you run multiple agents, only one Monitoring Agent and one Backup Agent per group or environment are primary. Only the primary agent reports cluster status and performs backups. If you run multiple agents, see Confirm Only One Agent is Actively Monitoring.
