Hi there …
Nagios newbie so please bear with me!!
Have been charged with rolling out Nagios as our new network monitoring system.
Everything so far seems to have the potential to work okay, except for “host down” monitoring.
From what I can see so far , the gap between a host going down and an alert being generated by Nagios is defined by the “check_interval” directive , and the least amount of time this can be set is one minute.
So potentially , it could that length of time before we are aware that one of our hosts is down.
However , for my purposes this is far too long , we require pretty much instantaneous notification ( or as close to it as is possible ) of a host being down.
Can greater checking interval of a host be configured anywhere??
Or perhaps a trap based solution be more feasible ??
Any help or pointers would be greatly appreciated!!
