I'm trying to monitor SMART on unix box using the check_smart.pl script. I have got it to work but it always reports "No Output!". The way I have set it up to work is like the following: In my services.cfg file I have it setup like this: define service { host_name Sentry service_description S.M.A.R.T - Status register 1 max_check_attempts 1 normal_check_interval 3 retry_check_interval 1 check_period 24x7 notification_interval 0 notification_period 24x7 notification_options w,u,c,r contact_groups ntadmins check_command "/usr/local/nagios/etc/scheck.sh SMART" } and in the scheck.sh file: if [ $1 = 'SMART' ] ; then /usr/local/nagios/libexec/check_smart.pl -t -d /dev/hda fi This works fine but it show up as NO OUTPUT within nagios. I want to be able to see the results of this command with Nagios. Does anyone know how to do this? Thanks in advance….. Neil </BODY> </HTML>
