Hi Team,
Thanks for your support.
Environment Details:OS: RHEL 7.2Postgres: 9.5.15Master-Slave with Streaming replication
We are planning to implement the monitoring tool for our environment.
Could someone please suggest the Monitoring Tool based on your experience.
We are looking to cover the below areas.
1. Monitoring metrics and alerting.
2. Monitoring events and alerting.
3. Consolidate all the PROD DB logs and provide insights on log data.
4. logging explain plan and insights on explain plans. (Something like store explain plan and compare plans and send alerts on deviations)
5. Logging audit data and insights from audit data.
Thanks & Regards,
Postgann.
For items 1 & 2, we've been working on a monitoring solution for PostgreSQL using Prometheus & Grafana called pgMonitor
We went this approach so it's not just confined to monitoring only PostgreSQL. You can monitor any other part of your infrastructure as well with the same programs.
For log monitoring (item 3), I would recommend pgBadger. https://github.com/darold/pgbadger
To get explain plans to be part of your logs (item 4), you can look at the auto_explain contrib module - https://www.postgresql.org/docs/current/auto-explain.html. I'm not aware of anything that would alert you on deviation from plans, and that would be quite tricky to implement. You can monitor for long running queries with pgMonitor and pgBadger can provide you with further insights on which queries are running long.
For auditing, I would suggest the pg_audit extension - https://github.com/pgaudit/pgaudit
So, there is not a single monitoring solution that provides all the items you're looking for, but there are solutions to each item available.
