Code Summary: Diagnostic Tools: mongostat

Review the following code, which demonstrates how to use the mongostat tool.

The following example uses mongostat to show the server statistics of a MongoDB cluster running at the URI mongodb+srv://dbaTestAdmin@cluster0.mntqoh9.mongodb.net.

mongostat “mongodb+srv://dbaTestAdmin@cluster0.mntqoh9.mongodb.net”

The next example demonstrates how to use mongostat to show the insert rate, query rate, and command rate in groups of three rows on the cluster running at the URI "mongodb+srv://dbaTestAdmin@cluster1.xwgj1.mongodb.net/". This command also specifies that the server statistics should be updated every two seconds.

mongostat -o='host,opcounters.insert.rate()=Insert Rate,opcounters.query.rate()=Query Rate,opcounters.command.rate()=Command Rate' 
--rowcount=3 "mongodb+srv://dbaTestAdmin@m0cluster-restored.iy0a1o4.mongodb.net"

The following options can be used with the mongostat command. Check out the MongoDB documentation for more information.
