2)。 Use mongostat to monitor in Shell

The serverStatus command is static monitoring, and MongoDB provides a dynamic monitoring execution tool, mongostat. Mongostat dynamically outputs some important information provided by serverStatus, once per second. Mongostat is used in the same way as the mongo client, using commands under the mongostat executable:

. / mongostat

If the MongoDB executable Bin directory has been added to the environment variable, use:

Mongostat
