Understanding Real-Time Monitoring
Cisco CallManager Serviceability provides a web-based tool that monitors real-time behavior of the components in a Cisco CallManager cluster. The RTM tool uses HTTP and TCP to monitor device status, system performance, and device discovery. It also connects directly to devices using HTTP for troubleshooting system problems.
See Figure 8-1 for an illustration of the Real-Time Monitoring window.
Monitor System Performance
The RTM tool displays performance information of all Cisco CallManager components in a cluster. The tool integrates with the Cisco CallManager administration and serviceability software. The RTM tool provides an alert notification mechanism to ease the system administrator troubleshooting tasks. The RTM tool monitors various aspects of the Cisco CallManager performance by periodically polling NT/2000 performance counter values.
Performance monitoring provides the following services:
•
•
•
•
•
Performance Monitoring Hierarchy
The Microsoft Windows 2000 operating system provides performance data that contains information for various object types, instances for each object type, and counters for each object type. The counters measure various aspects of system performance. For example, the object type, Cisco CallManager, includes the registered phones counter. The registered phones counter measures the number of registered phones. An instance designates a unique copy of a particular object type, though not all object types support multiple instances. For example, the object types Cisco CallManager or Cisco Tftp have no instances because only one CallManager or TFTP service exists on a Win2000 system. However, the Cisco Phones and Cisco Lines object types support multiple instances.
Consult Microsoft Windows documentation for more information about Windows 2000 objects and counters.
The following list defines performance monitoring hierarchy:

Each level of hierarchy supports a right-click context menu as follows:
•
•
•
Monitor Device Status
Real-Time Monitoring discovers devices regardless of their registration status (for example, registered or failed to register) in the cluster. The RTM tool searches on device name, device description, IP address, IP subnet, or DN and monitors the status of discovered devices.
Device status monitoring supports the following capabilities:

Resource Usage
If the system is running slowly, or calls are not getting through, you can view Cisco CallManager resources.
Last 24 hr. Calls
Serviceability monitors calls attempted and calls completed every hour for 24 hours (an automatic setting). See the following Note.
Note
Process Activity
You can view the Cisco CallManager process activity resource usage.
Directory Servers
Directory servers are database repositories that store user and device information such as user name, password, and location. The directory settings are similar to SQL. The Cisco CallManager publisher contains the directory. Each node in the cluster has its own copy of the directory. The directory supports three types: embedded, active, and Netscape. An embedded directory resides on the same node as its associated Cisco CallManager (other types reside on other nodes in the cluster). A directory that resides on the publisher node has write permission.
You can view the directory servers connection status. Directory server connection status and replication status get checked when an alert is pending. If the server is not connected, an alert occurs. The directory server connection status gets polled every 10 minutes; replication status gets polled once every hour. While directory server status displays in the resource usage window, you can click the Refresh button to update the directory server status.
About Real-Time Monitoring
You can view the About information for the RTM tool. The About window displays product name, client and server software versions, and third-party libraries software version information.
Help
You can view the Online Help information for Real-Time Monitoring, Serviceability or for all of Cisco CallManager.
RTM Monitoring Pane Options
The following list contains configuration options in the RTM monitoring pane:
•
•
•
•
Category Tabs
A category comprises monitored performance counters. A tab in the RTM 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.
You can create custom categories in the RTM monitoring pane to view information that helps you troubleshoot specific performance or device problems. If your Cisco CallManager 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 within the cluster. 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 using Preferences.
Sample Rate
The Cisco CallManager software polls counters, devices, and gateway ports to gather status information. In the RTM monitoring pane, you configure the polling intervals for the performance counters, devices, and gateway ports for each category tab that you create. For a description of the polling intervals for gateway ports, see Configure Refresh Rate for Gateway.
Note
Performance Counters Table View/Chart View
The Cisco CallManager software displays performance counters in chart or table format. Chart format looks like a miniature screen of information. Up to six charts display in the RTM performance monitoring pane for each category tab that you create. Because chart view is the default, you configure the performance counters to display in table format when you create a category.
Re-Select
To change the contents of the device monitoring pane without going to the device name in the Monitoring Objects pane, use the Re-Select option.
Understanding Performance Monitoring
You monitor the performance of the Cisco CallManager software by selecting the counters for any object. The counters for each object display when the folder is expanded.
Add a Counter to Monitor
To troubleshoot system performance problems, you add the counter associated with the performance object to the RTM performance monitoring pane, which displays a chart for the counter. Before you add counters, see RTM Window Overview, and Category Tabs.
Category tabs contain up to six performance counter charts.
Configure Alert Notification for Counter
Using the alert notification feature, Cisco CallManager notifies you of system problems. Perform the following configuration setup to activate alert notifications for a system counter:
