TRACE-CMD-LIST(1)           libtracefs Manual           TRACE-CMD-LIST(1)

NAME         top

       trace-cmd-list - list available plugins, events or options for
       Ftrace.

SYNOPSIS         top

       trace-cmd list [OPTIONS]

DESCRIPTION         top

       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         top

       -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.

               trace-cmd list -f '^sched.*'

       -P
           List the plugin files that get loaded on trace-cmd report.

       -O
           List plugin options that can be used by trace-cmd report -O
           option.

       -B
           List defined buffer instances (sub buffers).

       -C
           List defined clocks that can be used with trace-cmd record -C.
           The one in brackets ([]) is the active clock.

       -c
           List the available trace file compression algorithms.
