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
