We have devices which are normally offline, and we only need to be alerted when the device comes online. Is this possible with IPHost Network Monitor?

This is not directly supported for arbitrary monitor type but there are some workarounds:

1. You may create a reverse variant of PING monitor using WMI. To do so please create the 'WMI Query' monitor for localhost (host running the IPHost) and use the following custom WMI query:

SELECT StatusCode FROM Win32_PingStatus where (address='10.1.0.126' and StatusCode != 0)

Replace '10.1.0.126' with the actual IP address of your device.

2. If you don't want to reverse the actual monitor states shown in IPHost interface but just want to receive notifications ONLY if device goes online you may configure this using the Alerting Rules form. Using a Recovery checkbox you can trigger an alert when monitor leaves a particular 'bad' state, such as when your device becomes back online.

3. Another option is to use the "Script or Program" monitor and call some external custom script/program which would implement the reverse logic. Please contact support if you have any question on implementing such a monitor.
