Dotcom-Monitor device configuration settings allow you to send different alerts to different recipients based on the type of the device selected.
You can set up group alerting on the device settings page (Devices > the device Actions menu 
> Edit > the Alerts tab).
With the one-step interface, you can easily add notification groups to your monitoring device. Note that you can select multiple notification groups to receive alerts. In addition, the group alerting option allows you to create an alert escalation process that is based on the duration of the error condition.
See how to configure group alerting for a device in the Setting Up Group Alerting for Device article of Dotcom-Monitor Knowledge Base.
