> JOOI, why is it said that a host check degrades performance? As Giles Coochey mentioned earlier, host checks may cause performance problems because they are not scheduled in the same way as service checks. To quote the documentation again:
Also of note - when Nagios is check the status of a host, it holds off on doing anything else (executing new service checks, processing other service check results, etc). This can slow things down a bit and cause pending service checks to be delayed for a while, but it is necessary to determine the status of the host before Nagios can take any further action on the service(s) that are having problems. If your system can handle the overhead of running host checks every minute, that is fine, but I think people should be aware of the possible consequences of running "service-less" hosts. As for me, I just add a PING service to any host that doesn't have any other services. It does what you want, in that it can be scheduled to run every minute, but it doesn't slow down other processing. -- Bob Sloane, University of Kansas Computer Center, Lawrence, KS, 66045 Email:[EMAIL PROTECTED] http://www.ku.edu/home/sloane Phone:(785)864-0444 ------------------------------------------------------------------------- Using Tomcat but need to do more?
