Hi @dipankar2k2002,
#1 We provide PostgreSQL related metrics and Query Analytics which will help you to find bottlenecks and other issues in your DB. Which is a little bit different from what AWS provides AFAIK.
#2 Yes, it’s compatible, it can be added as Remote PostgreSQL Instance via our UI.
#3 No, we don’t keep logs of database on PMM side, PMM collects only prometheus metrics.
Best Regards,
Nurlan
