Have you ever encountered a transient performance issue, that was hard to investigate only from the database point of view? On top of how many layers of abstraction your database is working? What is the difference between running your database on a bare metal, VM or inside a container? PostgreSQL does not work in the vacuum, it heavily relies on functionality provided by an underlying platform. And sometimes to answer these questions above one needs to step back and look at a problem not only from a database point of view. In this talk we will discuss how to achieve that, how to tame such tools as strace, perf or eBPF to troubleshoot intricate issues and stay curious.
