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

       --verbose[=level]
           Set the log level. Supported log levels are "none",
           "critical", "error", "warning", "info", "debug", "all" or
           their identifiers "0", "1", "2", "3", "4", "5", "6". Setting
           the log level to specific value enables all logs from that
           and all previous levels. The level will default to "info" if
           one is not specified.

               Example: enable all critical, error and warning logs

               trace-cmd check-events --verbose=warning
