Bpftrace is a relatively new open source tracer for modern Linux (kernels 5.x.y) for analyzing production performance problems and troubleshooting software. Basic usage of the tool, as well as bpftrace-based one liners and small scripts useful for MariaDB DBAs (and even developers) are presented. Problems of MariaDB Server dynamic tracing with bpftrace are discussed.
