trace-cmd-list - Man Page

list available plugins, events or options for Ftrace.

Examples (TL;DR)

List available tracers: sudo trace-cmd list -t
List available plugins: sudo trace-cmd list -p
List available events: sudo trace-cmd list -e
List available functions: sudo trace-cmd list -f

The trace-cmd(1) list displays the available plugins, events or Ftrace options that are configured on the current machine. If no option is given, then it lists all plugins, event systems, events and Ftrace options to standard output.

Options

-e [regex]

This option will list the available events that are enabled on the local system.

It takes an optional argument that uses 'regcomp(3)' expressions to seach.

trace-cmd list -e '^sys.*'

-F

Used with -e regex to show the fields of the event.

--full

Used with -F which will show the "print fmt" of the event along with the fields.

-l

Used with -e regex to show those events filters.

-R

Used with -e regex to show those events triggers.

-s

This option will list the available event systems.

-t

This option will list the available tracers that are enabled on the local system.

-p

Same as -t and only for legacy purposes.

-o

This option will list the available Ftrace options that are configured on the local system.

-f [regex]

This option will list the available filter functions. These are the list of functions on the system that you can trace, or filter on. It takes an optional argument that uses regcomp(3) expressions to seach.
