Hi @Ramachandra_Tummala ,

My issue is similar to the one mentioned in the below thread.

3.4 MongoDB cluster upgrade to 3.6 and 4.0

Re @Stennie_X I’ve upgrade my rs to 4.0 version. The arbiter have the previous version only until 3.6 version. In 4.0 version, my arbiter have the current FCV rs01:ARBITER> db.adminCommand( { getParameter: 1, featureCompatibilityVersion: 1 } ) { "featureCompatibilityVersion" : { "version" : "4.0" }, "ok" : 1 } Besides rs.status and service status, are there any other ways to monitor the health of our cluster / rs? Thanks

Thanks
