Swap the flag orders, use --units or -u flag before the -M /usr/lib/nagios/plugins/check_disk -w 7% -c 5% -u GB -M /ocfs2/sap03 should work regards ranjib <div class="gmail_quote">On Thu, May 5, 2011 at 8:24 PM, Werner Flamme <<a href="mailto:werner.flamme@ufz.de">werner.flamme@ufz.de</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, I am fascinated by check_disk...
