Hello,

In our env, I deploy the original MongoDB3.4 sharding cluster with classic mode(3 mongod+1 mongos).  
I’m very confused when I use PMM to monitor the MongoDB cluster by “pmm-list add mongo cluster” command.

What is the cluster name for MongoDB cluster, In mongo’s config file,I just saw replSetName/clusterRole parameter.  
And if I need to monitor all shards,could I only add mongo url with mongos port?

could someone give me a sample command?  
Thank you for your help,and wait your reply.
