Hi Team,

I have enabled PMM2 and added AWS aurora mysql & postgresql rds instances to my PMM2 (via the discover method).  
I could see all db-related graphs but OS metrics are missing.  
Have enabled Enhanced Monitoring on the Aurora instance as well, can see the data in cloudwatch logs as well, But in PMM2 the graphs are blank

PMMVersion: 2.37.0

This has been fixed,  
We had a AWS IAM role-level permission issue to read the cloudwatch metrics, post adding the permission we could see the data.

Note: Please go through the PMM logs for all issues 🕶
