Useful DTrace scripts for FreeBSD
This repository contains various useful, ready-to-use DTrace scripts.
All scripts require root permissions.
In order to allow DTrace to show meaningful user stacks, you need:
-
to add ustack(); call to the corresponding probe script
-
to have these lines in /etc/make.conf:
## allow DTrace stack trace to pick up stack
STRIP=
CFLAGS+=-fno-omit-frame-pointer
CXXFLAGS+=-fno-omit-frame-pointer
CPPFLAGS+=-fno-omit-frame-pointer
-
to have proper symbols in the binaries by rebuilding the ports: portupgrade -f {port-name}
