Probes

Probes are made available by providers. Commonly available providers include dtrace,[5] for the BEGIN and END probes; profile, for profile and tick probes; and syscall, for system call entry and return probes. The full probe name is four fields separated by colons. See the other chapters of this book for more probes and providers, including Appendix C, Provider Argument Reference.

[5] This is a provider that is called dtrace. (DTrace is the technology, and dtrace(1M) is the command.)

Wildcards

Wildcards (*) can be used in probe fields to match multiple probes. The field foo* matches all fields that begin with foo, and *foo* matches all that contain foo.
