Dynamic tracing of MariaDB Server on Linux – problems and solutions
This video was presented at the MariaDB Server Fest, held online from 14-20 September 2020.
Linux OS with kernels 2.6+. provides different ways to add user probes to almost every other line of code dynamically, and collect the resulting trace and profiling data in a safe and efficient way. This session discusses basic use of ftrace, perf, bcc tools and bpftrace utility, highlights typical problems MariaDB DBAs and developers may hit while trying to apply them, as well as solutions to some of them.
