load average: 3.99, 4.56, 7.60 3.99 is the load on the server for the past 1 minute 4.56 past 5 minutes 7.60 past 15 minutes -w 15,10,5 Warn me if load is < 15 for the past minute or < 10 for the past 5 minutes or < 5 for the past 15 minutes In this case the load is < 5 for the past 15 minutes. Load is relative to a servers hardware including # of CPUs. So if you trust your server guy then you might want to adjust the check_load thresholds. -w 20,15,10 - This would stop the flapping. Or if you don't trust them you might want to cat /proc/cpuinfo, check service response times and otherwise verify they aren't overloading the server. ;) ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
