Watching nagios in debug mode for awhile, made me think about the processing of macros and the performance impact. It seems that for most macro's, like user defined ones, they don't change. So does it really make sense to keep processing them over and over and over...could that be something that maybe you could do in the pre-cache stage when nagios starts. Would that cause more problems?

If you have a large number of monitored hosts and services, you may want to look into "use_large_installation_tweaks": http://nagios.sourceforge.net/docs/3_0/largeinstalltweaks.html -- Breandan Dezendorf [email protected] [email protected] ------------------------------------------------------------------------ ------ Beautiful is writing same markup.
