Preparing backend mongodb instances for MMS (5)

This section describes the backend mongodb storage used to store the collected monitoring data and backup data for MMS. After MMS is installed, the following databases are automatically generated on the mongodb instance of backingdatabases. For MMS application database MMS monitoring, the mongodb replica set is required to save the MMS application database. This database storage: collects data from the Monitoring Agent

This section describes the backend mongodb storage used to store the collected monitoring data and backup data for MMS. After MMS is installed, the following databases are automatically generated on the mongodb instance of backing databases. For example, the MMS application database MMS monitoring requires the mongodb replica set to save the MMS application database. This database storage:

• Monitoring data collected from the Monitoring Agent
• Metadata, such as MMS users, groups, hosts, monitoring data, and backup status

What is the hard disk required for up to 400 monitored hosts? 200 GB storage space; for up to 2000 monitored hosts, the hard disk requires GB of storage space. The database of this application should be a MongoDB replica set composed of three instances. If you cannot allocate three data instances, you can add two data instances and one arbitration node. SSD storage can be used for optimal results. You can also use a separate mongodb instance to replace the replica set. However, it is not recommended in the production environment. Optional: an independent and dedicated MongoDB replica set is required for MMS backup of the Blockstore database to save the backup snapshot data. The system should have enough capacity to store 2 to 3 times the total backup data size. Install and configure the replica set. For more information, see mongodb replica set.
