Categories allow you to organize objects in RTMT, such as
performance monitoring counters and devices. For example, the category, Cisco
SIP Proxy, allows you to monitor performance-monitoring counters in graph
format for the SIP proxy. If you want to monitor more counters, you can
configure a new category and display the data in table format.
A category comprises a group of monitored performance
counters. A tab in the RTMT monitoring pane contains the category name. All
performance counters that are monitored in this tab belong to a category. The
system polls the performance counters in the tab at the same rate, with each
category configured to have its own polling rate.
If you perform various searches for devices, for example, for
phones, gateways, and so on, you can create a category for each search and save
the results in the category.
You can create custom categories in the RTMT monitoring pane
to view information that helps you troubleshoot specific performance, system,
or device problems. If your system is experiencing performance problems with
specific objects, create custom categories to monitor the performance of the
counters within the object. If the system is experiencing problems with
specific devices, create custom categories to monitor the devices in your
system. In addition, you can create alert notifications for counters and
gateways in these custom categories. To create custom categories, you add a new
category tab. When the tab is created, you specify the specific performance
counters, devices, and alerts within that tab and then save your custom
category by using Profile.
