Nagios Support Forum

Hi Team,

I have created Custom Script Monitoring and using it to Monitor ( which seems to be working fine ) , but would like to understand its behaviour when plugin TimeOuts happen ? Does this cause the Monitor Fail ( report Down on Performance Graphs ) or will be ignored because i didnt see this on Event log or Alert Log ( these failures are only there on Notifications ) ?

Can you help me understand how Plugin Timeouts are handled , and also Does this log as Event/Alert and any difference with Notifications ?

You can set the amount of checks ( max_check_attempts ) and the time interval between checks. So, the conditions and the amount of time before your host is considered down or unreachable by our system is highly configurable.

It may also be useful to know that Nagios makes a distinction between hard and soft checks depending on the certainty of that state. A hard check consists of a set of checks that are unanimous in their reply, and a soft one would be a set of checks that returned mixed results.

Please refer to the following linked documentation for more information.

Thanks . So does the TimeOuts fall under Soft state ?

Any state could return as soft or hard. It is just an indication of how consistently a check returns a certain result, and is designed to reduce the amount of notifications generated by false positives.

A TimeOut occurs when a host is unreachable for any check in a series. In that sense, the term TimeOut does not equate to soft or hard, but is more related to when a host registers as being in an unreachable state by the Nagios core.

Thank you !
