I am using PMM2 for monitoring all my RDS instances.
I added Postgres as a remote database, But by adding a database as remote in PMM2 we miss host-level metrics like CPU, Memory etc. What is the recommended way of adding Postgres (RDS) or a way to inject missing metrics to get the complete Node Summary?
We have also faced the same issue.
In PMM1, we had the cloud-watch as data-source, which was used get the host-level metrics. Now, in PMM2, this has been removed; hence, you can't get the metrics.
To get the metrics, add cloud-watch source plugin and import the dashboard from PMM1.
