Is it possible to set normal_check_interval to under 1 minute intervals?
How do you specify a timeframe < 1?
I strongly suggest you read the nagios docs and also make sure you understand what each and every single setting in that nagios.cfg file actually does and is used for. If not, then you will never truely know nagios.
Thanks for the info and I'll read the docs again.
What about if you want to leave most service checks with a default of 1 minute, and some checks to occur every 15 seconds?... can you simply use normal_check_interval=15s to override the interval_length?
