I am experiencing again a weird case where CRITICAL notification was not sent out and only OK was sent. Something similar to a problem i had before: https://support.nagios.com/forum/viewto ... 16&t=50747 Service settings:

looking at your first image, it is hard to see for sure but it looks like the host that is sending the notification start with an a and a s and the host that is logging a SERVICE ALERT starts with an o

So these aren't the same host/service combination.

Thats incorrect, "a" and "s" are actually users(contacts) line structure is like this
SERVICE NOTIFICATION: a(user);o(server);Oracle tnsping(service);OK;xi_service_notification_handler;OK - connection established to o(server:port/DB)

Ok got it!

Is it possible that this was the first time this service went into an OK state since upgrading to 5.5.9?

I ask because there was a bug in previous versions that could cause this and they would not reset themselves and thing that a notification had previously been sent when it hadn't.

This actually shouldn't have sent the CRITICAL notification because it was just a soft state, but the errant recovery was part of the bug mentioned above.

Yes, it indeed went into CRITICAL/OK state first time after upgrade. Thank you and i will let you know if this happens again.
