This topic applies to all Orion Platform products except for the following products:

APMEOCETSWPM

There are situations when multiple devices go down, and instead of getting an alert for each device, you only want to receive one alert that notifies you that something is wrong. A multiple device alert is closely related to a dependency alert, where Orion detects a down status for a network element because an object in front of the network element is down. For example, if a router goes down, Orion detects that all servers behind the router are also down because Orion cannot communicate with the servers. But, the servers behind the router are still physically up, they are just reported as down. In this case, the alerts triggered can be numerous and inaccurate. You can create a dependency between the router and servers so that when the router goes down, only a single alert is triggered.

With a multiple devices go down alert, the devices reported as down are actually down. For example, you monitor the network connections to multiple remote sites. You need an alert that notifies a group that addresses network issues, like when the carrier loses connectivity to several sites simultaneously. Unless you configure the alert to trigger when multiple devices go down, you will receive one alert for each site. The following alert only triggers when more than 10 sites go down at the same time.

Use groups

You can also use groups to alert you when multiple devices go down. In this approach, create a group and assign related devices to it. In this scenario, an alert is only triggered when all devices in the group are down, and not just a subset of devices. Using groups saves you time when configuring alerts, and is also useful when you have load balanced devices and you only care when all the devices are down, not just when some are down.
