I always like using the nagios process check myself rather than checking
for the ".pid" file as I have had nagios die off and the ps wasn't
telling me anything, I use this which works pretty good for me, I also
use this along with additonal and modified to check our nagios primary
to make sure it's up and if not startup slave etc.
Might want to give this a try, edit according to your install of
course :
#!/bin/bash
plugindir="/usr/local/nagios/libexec"
cmdstart='/sbin/service nagios start'
#Check nagios with check_nagios plugin
$plugindir/check_nagios -e 5 -F /usr/local/nagios/var/nagios.log
-C /usr/local/nagios/bin/nagios
if [ "${?}" != 0 ] ; then
echo "CRITICAL:Nagios not found running..."
$cmdstart
else
echo "OK:Nagios runnning..."
fi
exit
