Percona Live Online

The popularity of DBaaS cannot be denied. They are incredibly helpful for growth not only due to the operational tasks assistance but also for monitoring and visibility of database internals. In the case of RDS, Amazon provides pretty cool features other than the well-known CloudWatch: things like Enhanced Monitoring or Performance Insights are fantastic....but they came with a (unusually high) cost.

Enter PMM: The Percona Monitoring and Managing tool. PMM being highly customizable and based on well-known open source tools, appears as a great alternative, especially for DBA teams that require deep understanding of what is going on inside the databases.

However, PMM also require a considerable amount of time and effort to have it the way we wanted, especially for PostgreSQL.

Our journey involves work on several aspects like:
- PMM server capacity
- Limitations due to being at a DBaaS
- Several dashboard customization
- Additional data sources via custom queries and textfile-collectors
- Grafana tune
- Prometheus magic
- And some hacking...
