CPu consumption too high

[Todd Barbera]

Given that your CPU's are showing 97 and 99 percent usage by system resources, it sounds like an OS process is chewing up your CPU. Have you run "top" or another similar utility? sar, iostat, and vmstat are useful tools for helping track down performance issues. I know these are available on Solaris, but I can't speak for other *nix servers. Also, since your server has been running for over a year, there's a good chance you're well behind on your OS patch levels. It could be you've hit some sort of bug within your OS.

  Hello All,

  I use Nagios 2.0b5 and I have only 210 services.
  The problem is that my server is running out of ressource 
   10:42:05  up 423 days, 19:36,  3 users,  load average: 8.18, 7.29, 6.54

  But nagios don't use so much ressource : 
   10:42:35  up 423 days, 19:37,  3 users,  load average: 8.63, 7.47, 6.62

  I am using apan with nagios but it shouldn't take so many ressource.


  Does someone have an idea please ?
