trace-cmd-check-events

TRACE-CMD-CHECK_EV(1)													     TRACE-CMD-CHECK_EV(1)

NAME

       trace-cmd-check-events - parse the event formats on local system

SYNOPSIS

       trace-cmd check-events [OPTIONS]

DESCRIPTION

       The trace-cmd(1) check-events parses format strings for all the events on the local system. It returns whether all the format strings can
       be parsed correctly. It will load plugins unless specified otherwise.

       This is useful to check for any trace event format strings which may contain some internal kernel function references which cannot be
       decoded outside of the kernel. This may mean that either the unparsed format strings of the trace events need to be changed or that a
       plugin needs to be created to parse them.

OPTIONS

       -N - Don't load plugins

SEE ALSO

       trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-stop(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1),
       trace-cmd-list(1), trace-cmd-listen(1), trace-cmd-start(1)
