the right thing is to find where $SYSLOGD_OPTIONS is defined and add -x to that
however, in this case, the line that's commented out has the -x on it, just
switch which line is commented out should work
If you are still having problems, try and start it manually
just doing rsyslogd -x will probably get you a running rsyslog
you can get debug output by doing rsyslog -x -dn, but that produces a LOT of
output and significantly slows rsyslog down.

Thank you David, where exactly do I need to start rsyslog with -x? from the
init.d/rsyslog or the sysconfig/rsyslog ?
start() {
[ -x $exec ] || exit 5
umask 077
echo -n $"Starting system logger: "
# daemon --pidfile="$PIDFILE" $exec -x -i "$PIDFILE" $SYSLOGD_OPTIONS
daemon --pidfile="$PIDFILE" $exec -i "$PIDFILE" $SYSLOGD_OPTIONS
RETVAL=$?
echo
[ $RETVAL -eq 0 ] && touch $lockfile
return $RETVAL
}
When I do it from init.d/rsyslog and I de-comment the daemon line and run -x
from there , no logs are written?

If things are working most of the time, but occasionally you are seeing lots of dropped messages, I would
be looking at DNS issues. One of the big reasons to disable DNS lookups on UDP rsyslog servers is that DNS
can take an unknown amount of time to resolve (up to several seconds), and during that time, additional new
messages cannot be processed, if you don't have insanely large buffers setup in the OS, this will cause you
to loose messages. Try starting rsyslog with -x (to disable DNS lookups) and see if you still have the
problem what version are you running? you should upgrade to 7.x and see if the problem reamins (lots of
improvements, including a DNS cache compared to 5.x and earlier) David Lang On Fri, 30 Aug 2013, Robert
