I know there is an e-mail alert configured in RTMT to trigger when registered handsets drop by x%
However, I need to configure an alert when any single device is unregistered. As I have 700+ devices, setting an alert on "1%" unregistered is not sensitive enough. Setting the alert to "0%" seems to make the default setting if "10%" apply.
I've got a problem with handsets going missing. For the short-term I wanted notification if any are disconnected. I understand that in the long term, alerts like this would be too overwhelming and that the alerts in RTMT are to identify significant service issues, but have a short-term requirement to monitor this closely.
Does anyone have any suggestions ?
