Andre,
I wouldn't acknowledge it unless you plan to actually do something about it.
I use escalations which instigate callouts to engineers. When the oncall
engineer acks an alert it means they are investigating. It would be pointless
surely to ack something which you aren't going to do anything about.
Also, think about why you'd ack at 80% if it's just a warning. We have
thresholds of 85% for disk usage warnings but in all honesty it's there as
exactly that - a warning. We don't send notifications for warnings on disk
usage. We just monitor via the web interface. Notifications are sent on
critical alerts because that is the time when action needs to be taken and
users need to pay attention.
But this is all based on our requirements rather than yours so this is just my
tuppence worth!
Regards,
Deborah

Subject: [Nagios-users] Notification after Acknowledgment
Hi
Can you guys please give me your input on how you handle the following
situation.
Lets take monitoring a disk as an example. For arguments sake lets say when the
disk reaches 80% capacity I send out a warning and at 90% I send out a
critical. There is also a Service Escalation configured to send out
notifications when this service reaches critical.
So at 80 percent I get my notification all is well. I then go ahead and
acknowledge the event and in doing so Nagios will not send out any further
notifications. Which according to the Nagios logic is correct.
The problem is if the disk in the mean time reaches critical, 90% capacity, I
won't get another notification. Not even the Service Escalation helps here,
because the event has already been acknowledged.
Do you guys have any suggestions on how this problem can be solved?
Regards
Andre
