+Monitoring a DeviceGroup
+------------------------
+
+The performance of a Device Group can be monitored in many ways, by clicking its |monitor| (**monitor**) icon:
+
+* From the *VCS Monitor* page, which shows all DeviceGroup's belonging to an VCS.
+* From the DeviceGroup List Page - click the |monitor| icon for the DeviceGroup.
+* When editing an existing DeviceGroup - in the Edit page, the |monitor| is next to the *id*
+
+The *monitor* page itself shows:
+
+* An information Panel for each *IMSI Range* in the *DeviceGroup*
+
+    * Each UE has a |monitor| button that allows further drill down
+    * Each UE is shown with its fully expanded IMSI number (a combination of *Imsi ID* and *Site* parameters)
+* An information panel for the *Site* and *IP Domain* of the *DeviceGroup*
+
+    * Clicking on the down arrow expands each panel
