Hi, I'm scratching my head trying to figure out how to get HQ (open source version) to notify me when the win32 server is down or interrupted, without flooding me with messages.
It appears the availability parameter is actually an average instead of an actual value, which makes it difficult to come up with good criteria (so far!). For example, I would like to know when the actual availability is less than 100% anytime within an hour, but I don't want false messages, so I assume I should wait for 3 or so values less than 100% (default measurement period is 1 minute). The problem is, the average stays below 100% long after the network/server has recovered and is actually at 100% availability.
The best idea seems to be to enable the action when the availability=0 for at least 5 minutes in one hour. However, since the availability is an average I would not get a message until the average was dragged down to 0, which could be some time. If I try to pick a percentage, then I'm kind of guessing at when the threshold is crossed. Plus if I just get a couple of random dropouts in an hour that happen to add up to 5 minutes below my threshold, I don't want to get beeped (I already know my network is very unreliable!)
I'm hoping I have just overlooked an easier way to set it up, so if anyone knows the secret, I would appreciate knowing. Is there maybe a way to make availability be an average of only 1 measurement point?
Thanks,
Matt
