mongo_ops_operations_agent_management

As already discussed the OPS Manager is centralized based manager for Mongo. Ergo it has server and agent. Agent should be also running on the OPS Manager server, so let's check how stop start an agent:

We can check the status of the manager as follows (on the manager machine of course)

Check status of Ops Manager

[root@dbpafxjrl ~]# service mongodb-mms status
Check Ops Manager status
   Probing instance 0...[  OK  ]
      The instance is running.
Check Backup Daemon status[  OK  ]
   Backup Daemon Process is running.
[root@dbpafxjrl ~]#

We can also start it as follows:

Start Ops Manager

[root@dbpafxjrl ~]# service mongodb-mms start
Starting pre-flight checks
Successfully finished pre-flight checks

Migrate Ops Manager data
   Running migrations...[OK]
Start Ops Manager server
   Instance 0 starting............[OK]
Starting pre-flight checks
Successfully finished pre-flight checks

Starting Backup Deamon....[OK]
.........................
[root@dbpafxjrl ~]#


Agent is installed on the server and the destination hosts and should be running everywhere. So let's see how to check it's status and how to stop start it:

Status of Agent process

[root@dbpafxjrl ~]# systemctl status mongodb-mms-automation-agent.service

Start Agent

[root@dbpafxjrl ~]# systemctl status mongodb-mms-automation-agent.service
