mongo_ops_operations_agent_management [My wiki]

This is an old revision of the document!

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:

Status of Agent process

[root@dbpafxjrl ~]# systemctl status mongodb-mms-automation-agent.service
● mongodb-mms-automation-agent.service - MongoDB MMS Automation Agent
   Loaded: loaded (/etc/systemd/system/mongodb-mms-automation-agent.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

Start Agent

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