Hi Team,

Would like to confirm if there is any limitation while using QAN, enables QAN in mongoDB sharded cluster, but only getting find,delete,update queries, no queries for aggregation.

Hello, there should be no limitation. Do any aggregation queries show in the system.profile collection?

Thank you for quick response, but no aggregation results found on query section while shard cluster.
Also would like to confirm does PMM require any additional setting/parameter for cross DC.

For example:
replica set1 - 3 machine is in different subnet and 2 machines is in different subnet.

As long as the replica set members can reach the PMM server port 443 there is no problem.
