Check interval seems like it's not doing what I ask

Nagios
1

Hi folks,

I’m sure I have a misconfiguration, as I don’t understand why Nagios is not scheduling a check when I would expect. Here’s the situation. I had a service go down at app. 4:00am this morning, and a notification followed soon after (within several minutes). Now, the service is back up, but the next sceduled check is showing as about 45 minutes from now. Since the normal_check_interval is set to 5, I would expect to get a notification that the service is back up within 5 minutes of when it came back up. Any advice would be appreciated, here’s some info. I’m running version 1.2

Thanks,

could somebody have rescheduled the next active check at that time from the web interface? it’s the only idea i get…

Nope, I’m the only one who uses it.

Thanks for the reply though. Anyone else have any ideas?

Do you have any escalations defined? I’m not sure whether or not you can define different check intervals in escalation configs, but it might be worth looking into.

No, I have no escalations defined either.

obsess_over_service 1 Why do you have that and so what is your ocsp_command=???

What is inter_check_delay_method=???

To be honest, I don’t know why that option is set. Maybe I didn’t understand what it was for when I first set this stuff up. I’m setting it to 0 now.

inter_check_delay_method=s

I’ve got 65 services over 23 hosts configured. I’ll look over the above parameter and see if that answers my question.
