Overview¶

If the Monitoring Agent cannot collect information from a MongoDB process, On-Prem MongoDB Management Service stops monitoring the process. By default, On-Prem MongoDB Management Service stops monitoring a mongos that is unreachable for 24 hours and a mongod that is unreachable for 7 days. Your group might have different default behavior. Ask your system administrator.

When the system stops monitoring a process, the Deployment page marks the process with an x in the Last Ping column. If the instance is a mongod, On-Prem MongoDB Management Service displays a caution icon at the top of each Deployment page.

You can reactivate a deactivated instance whether or not it is running. When you reactivate a host, the Monitoring Agent has an hour to reestablish contact and provide a ping to MMS. If a host is running and reachable, it appears marked with a green circle in the Last Ping column. If it is unavailable, it appears marked with a red square. If it remains unreachable for an hour, MMS deactivates it again.

You can optionally remove a host that you are no longer using. Removed hosts are permanently hidden from MMS. For more information, see Remove Hosts.
