I wanted to know if there is a way to disable notifications for a device, if a certain service on a different device has gone down.
For instance: (Device 1) and (Devices 2 till 30) all have a ‘ping’ service with an ‘e-mail’ notification. If the ‘ping’ on device 1 dies and I get an e-mail, I already know that (Devices 2 till 30) are down as well, and I don’t want to get 29 extra e-mails. How can I remedy this?
You can make devices dependend of each other.
Let say, you have a router, it goes down and any server behind it should be seen as down.
To avoid many alerts for any server you can make servers depended on router and when router will be down servers behid it will be in unknown state, and the will be no any alert for servers.
To make device depended on other devices look at sample
Asume that Dude server is somewhere in internet.
The dependance shows how the packet flows from Dude to device.
If switch will be down WinXP station will be in unknown state, if router will be down swith and workstation will be in unknown state. When device goes in unknown state it does not generate any alert.
In a such a situation you also should make router to go in down state faster then other devices. To do it you may check it ping status more frequent.
