What kind of information do you have about average CPU load or I\O wait time? Whether Nagios is using ndoutils or not there will be a hardware limit as to how many disk writes it can handle in a given period of time. Even though you're only running a few active checks, it could be a symptom t

If you go to "Acknowledge" a host or service in a problem state, there is a checkbox for whether or not to send a notification. If you want the notification use the "Acknowle this service problem" link instead of the "Add Comment" link. On 5/21/2012 5:41 PM, Ajay Jethani wrote: I'd like nagi

This could be the case. Is there a way I can log and explicit find out some traces that could point me to the real causes? I'm collecting on MySQL everything is generated by nagios itself: status and performance data, which are a lot of informations: 7GB of runtime statistics. Il 22/05/2012 1
