I would like to present a new utility called dwatch that I added to FreeBSD 12.0 Using dwatch, in this talk you will learn how to: Watch processes entering system CPU scheduler Print arguments being passed to functions Easily watch multiple probes simultaneously Globally watch all function traversal from every process/thread Filter output by user or group, including the ability to use regex Watch jail activity Use patterns or regular expressions to match on executable name(s), pid, etc. Look for a particular path being created, removed, accessed, etc. Watch interprocess communication signaling Log network data events Schedule timed samplings for events of interest Dump process trees for processes triggering a probe Watch child processes Show commands being executed in realtime Write modules to centralize logic into easy-to-access profiles Share modules with each other and help your community More... With dwatch, using DTrace has never been so fun and painless.
