<html> <body> Most Linux distros, I am aware anyway, support share memory segments. the How about a mechanism, supported by Nagios of course, where we could save some variables to a shared memory segment. Saving and retrieving should be pretty quick. Doug Veldhuisen Running Nagios 2.5 on Debian and Fedora.

I can see value to having a $SERVICEPREVOUTPUT$ macro that could be passed to a check plugin. That would be an easy way to allow for this commonly requested functionality. -- Flow -- <x-tab> </x-tab>(Service check execution time) <x-tab> </x-tab> $SERVICEPREVOUTPUT$ = $SERVICEOUTPUT$ <x-tab> </x-tab> $SERVICEOUTPUT$=NULL <x-tab> </x-tab>(Execute Plugin) <x-tab> </x-tab> $SERVICEOUTPUT$ = <Plugin output> -- Marc ------------------------------------------------------------------------- Using Tomcat but need to do more?
