No. Nagios forks after (optionally) caching the plugin in memory, bringing the embedded perl stuff with it. The child runs the cached plugin. The saving is entirely in avoiding to load /usr/bin/perl each and every time a plugin is run (at the slight expense of copying some more memory at every fork if epn is compiled in). > > Multiplexing is another thought, that too introduces complexitities, > that I understand as well. > Multiplexing would be the way to go. It's the most complex, but the most portable and the least resource-hungry. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
