Have you tried changing the time window from the default 12 hrs to something like 15 min? I have noticed that newly added systems appear to have not stats until the time window is reduced. ---

Hi Steve, Yes I did , I tried different options , updated the time , drooped and recreated the user. One thing I noticed if follow the same steps for replica set only , I can see the stats. It’s just that it’s problematic with sharded cluster Thanks, Bhaskar ---

Why are you using --skip-connection-check ? that might be hiding some errors. Also I see you are using TLS so you might need the FQDN in the --host argument. I would advice you to try the following: > sudo pmm-admin add mongodb --username mongodb\_exporter --password xxxx --host=[MySha1Rep1.domain.com](http://MySha1Rep1.domain.com) --port=50002 --cluster MyTESTCluster --tls --tls-certificate-key-file=/certlocation/mongo.pem --tls-ca-file=/certlocation/ca.crt ---

There should be nothing else required. Are you using same client and server versions? I suggest you update both to latest PMM 2.17 to see if it solves the issue. ---

@Ivan_Groenewold : i was able to get my dashboard working , i am currently using SSL Certs with combination of SCRM-SHA authentication, i updated my security setting from requireTLS to preferTLS and added mongodb without certs, then the dashboard started working. Now question is , do i have to make any specific changes with certs for me to access mongo through PMM dashboard. ---

Hello, it should work with requireTLS as well. There might be a problem with the client certificate. You can try the pmm-admin add mongodb with --tls-skip-verify to see if it makes any difference, or also the --debug argument.
