Hi Team, We are on Percona server for MongoDB 4.4 version. PMM Client version - pmm2 PMM server is Installed using Docker Image. When we are trying to configure PMM for our MongoDB replica sets. Even though, when we add **–replication-set** tag, It is not being detected in the MongoDB Replica Set summary dashboard. I have used the below command to add the nodes to PMM. (Ran this command on all the 3 nodes present in the replica set). pmm-admin add mongodb --username=pmm --password=password --environment=DEV --replication-set=replication\_name --authentication-mechanism=SCRAM-SHA-1 Can you please review and help me out. Thank you Kiran ---

Hello, you don’t need to provide the --replication-set flag as PMM will automatically detect the members of a replica set based on rs.status() output. Try adding as follows: `pmm-admin add mongodb --username=pmm --password=password --environment=DEV` Also make sure you select the Last 5 min in the dashboard, and give it 1-2 min time to populate to check for the new member. ---

Hello Ivan, Thank you for your response. I tried adding the service without --replication-set flag but, unable to see the replicaset on the dashboard. Below is the screenshot of pmm-admin list post service addition. ![image](https://us1.discourse-cdn.com/flex019/uploads/percona1/original/2X/5/5419fd4dcbe0556cc84ca34f602b7385e71aff3e.png) Do we need to enable any setting/change configuration for the replicaset to be displayed on the dashboard? Please help me out. Thank you, Kiran ---

Hi @Ivan_Groenewold We were able to figure out the Issue here. pmm-server version we are on is 2.20.0 pmm2-client version is 2.29.1 We tried upgrading the docker image of the pmm-server to 2.28.0 and It resolved the Issue. (Are there any version specifications[server and the client] that you recommend while configuring the PMM? Thank you for your time and help on this. Regards, Kiran ---

Hello, glad to hear you sorted it out. As per [the manual](https://docs.percona.com/percona-monitoring-and-management/how-to/upgrade.html) always use a PMM server version higher or equal to the client. Ideally they should be the same version except during an upgrade.
