The version of nagios you are using would be critical information. In nagios 2.x, active host checks are run in serial, not in parallel and are highly discouraged because they introduce significant latencies. In 3.x, they've been made to run in parallel. I'm guessing you're using 2.x. Nagios is primarily a service monitoring application and is designed to monitor services. Host monitoring is typically only done on an as-needed basis. > Another problem is that after i update my config file, verify and restart > nagios, it takes 15 mins for the web interface to register the change. Are you using ndoutils? With that few hosts and services the change should be immediate. Do you see that your objects cache file contains the new information? Do you have multiple nagios daemons running at the same time? > Are the 2 problems linked? Not in any way that I've ever seen. -- Marc ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.
