Be notified if 2 redundant devices go down

Hi,

I wonder if there is any way to monitor 2 devices, and get one notification only if both go down.
I have a lot of redundant devices on my network, and i need to be notified, day or night, if they are down, but only if they are both down.

I don’t want to be disturbed in the middle of the night if only one is down, it can wait until next morning to be solved.
But if the malfunction affects both devices… well… :open_mouth: I really have to solve it.

I don’t know of a good way to do event correlation in the dude… Maybe someone else does.

Simple event correlator can coordinate log messages into precise notifications. http://simple-evcorr.sourceforge.net/ You will need a Linux box and a little perl know how.

can’t you put both of them in a submap, and set up notification if all of the submap is down (both devices)?

Hey Normis I looked around but didn’t see how you accomplish your suggestion could you explain it? Thanks!

you can configure notifications on a per-map basis, can’t you? when all devices in a submap go down (submap icon turns red), then run some notification. to all you need to do, is put those two devices in a separate map, and configure the map to send a notification.

After looking yes it should be simple right? Select notification on a map, create new notification, put the description of the map in the new notification, set the appropriate options and you should get an email since the map status changes from up to down but I did not get an email also the map went from up to down when only one device was down. I’ll think about it and get back if I come up with another way.

That is not right.
The notification is triggered when service is changing it’s state. It is not related to map at all.
The only solution is to create probe which will use ping function for both ip addresses of related devices.

sorry, you are right. those are only default settings for the devices inside this map. map settings override global settings, and individual settings override both the map and global settings, but they are all still individual notification settings for devices.

ie. if you set up notification parameters for the map, it will ignore your global defaults, and if you set up nofication settings per defice, it will ignore any more generic defaults.

currently there is no simple way to do what the OP asked
