PMM not picking MongoDB

Percona Monitoring and Management (PMM) PMM 1.x
1

Hello, I installed PMM Server from AWS Marketplace on a separate EC2 (PMM-EC2). I am trying to monitor mySQL and MongoDB that are installed on the same EC2 (DB-EC2). I installed PMM client on the DB-EC2 and ran the list command for which the output is below. In the Grafana dashboard the MySQL shows up but MongoDB does not. It shows ‘Monitered DB Instances’ as only 1 … it should be 2 including MongoDB and MySQL.

Hello there, I’ve asked the team if they’ve any advice for you on this, just wondering if you could confirm the version of PMM you have installed?
Did you try to set the connections to MySQL and MongoDB at the same time or has the MySQL one been running for a while?

I’ll pass you this link ‘just in case’ it helps, but I think that there might be some new tips and tricks for your environment … [url]https://www.percona.com/blog/2018/01/17/troubleshooting-percona-monitoring-and-management-pmm-metrics/[/url]

Hi mr.debater
Can you please share (from DB-EC2 client) the contents of

/var/log/pmm-mongodb-metrics*.log

Also can you share the commands you ran to set up the MongoDB instance? It will be the

pmm-admin add mongodb ...
