Hi Guys,
Am currently running nigios to monitor our servers. However, nagios seems to move kinda slow going through it checks. Say I have a service setup to be checked every 1 minute and 5 times before a notification is sent. You will think this will take about 5 minutes. This actually takes about 20 minutes because nagios takes quite a long time before it gets back around to check the service. I also niticed some strange warnings in the log which I think may be the cause of this problem. Any suggestions on how I can tune nagios will be helpful. See the log entries below.
