The previous recipes, Signing up for MMS and setting up the MMS monitoring agent and Managing users and groups in the MMS console, showed us how to set up an MMS account and agent, add hosts, and manage user access to the MMS console. The core objective of MMS is monitoring the host instances, which is still not discussed. In this recipe, we will be performing some operations on the host that we added to MMS in the first recipe, and we will monitor it from the MMS console.
Follow the recipe Signing up for MMS and setting up the MMS monitoring agent and that is pretty much what is needed for this recipe. You may choose to have a standalone instance or a replica set, either ways is fine. Also, open a Mongo shell and connect to the primary instance from it (it is a replica set).
