User Devices

Operations Monitor provides statistics for user agents (user devices) registered on the monitored platform. These statistics are based on the User-Agent header of the REGISTER request. Alternatively, Operations Monitor can also evaluate the User-Agent headers of INVITE requests and replies in order to provide statistics about the callers and callees of the user device.

The User Devices page is located under the Voice/Video Operation section of the main menu. The User Devices panel displays a pie chart of the found user agents. The Devices List table contains detailed information about each user device in the lower area.

User Devices Chart

The User Devices chart displays the relative frequency of user agents as shown.

Operations on User Devices

You can filter and group user devices with the following actions in the User Devices chart:

Select data source
You can select whether the statistics displayed on the User Devices page is based on registrations, callers, callees, or subscriptions. To choose a display, select one of these from the drop-down menu to the left below the chart:
- View Registration
- View Callers
- View Callee
- View Subscriptions
The information stored for callers and callees is based on the list of calls that Operations Monitor keeps in memory.
Restrict the User Devices page

You can specify the statistics on the User Devices page to match or not match a certain regular expression. Enter a regular expression into the text field to the left of the filter button below the chart. Click Filter. If you want to invert the match, mark the Invert check box below the chart.
Group devices

To create a new group of user devices, enter a regular expression in the Filter for device field and click the Create group button. The new group rule is applied to the Device List panel (below the chart). If the Show grouping check box below the chart is marked, the groupings are also applied to the pie chart.
