Understanding Alarms

Cisco Unified CallManager Serviceability Alarms provides a web-based interface that configures alarms and events and provides alarm message definitions. Both functions assist the system administrator and support personnel in troubleshooting Cisco Unified CallManager problems.

You use Alarms to provide run-time status and state of the Cisco Unified CallManager system and to take corrective action for problem resolution; for example, to determine whether phones are registered and working. Alarms contain information such as explanation and recommended action. Alarm information includes application name, machine name, and cluster name to help you perform troubleshooting, even for problems that are not on your local Cisco Unified CallManager.

You configure the Alarm interface to send alarm information to multiple destinations, and each destination can have its own alarm event level (from debug to emergency).

You can forward alarms to a Serviceability Trace file. An administrator configures Alarms and Trace parameters and provides the information to a Cisco TAC engineer. You can direct Alarms to the Win2000 Event Log, Syslog, an SDI trace log file, an SDL trace log file (for Cisco CallManager and CTIManager only), or to all destinations. Use Trace to collect and analyze the alarms.

When a service issues an alarm, the alarm interface sends the alarm to the chosen monitors (for example, SDI trace). The monitor forwards the alarm or writes it to its final destination (such as a log file).


Note To log alarms in the SDI trace log file, check two check boxes in Trace configuration and one check box in Alarm configuration: the Trace on check box in Trace configuration, the Enable trace file log check box in Trace configuration, and the SDI alarm destination check box in Alarm configuration.


Alarm definitions describe alarm messages: what they mean and how to recover from them.

You search the Alarm definitions database for alarm information. When you click on any service-specific alarm, a description of the alarm information and a recommended action display.

Alarm Configuration

You configure alarm information that will be used for Trace and troubleshooting. You can configure alarms for Cisco Unified CallManager servers that are in a cluster and services for each server, such as Cisco CallManager, Cisco TFTP, and Cisco CTIManager.

Alarm Monitors

The alarm interface supports up to five alarm destinations, or monitors. The following monitors receive alarms:

Event Log

SDI trace (can be viewed in text or XML format)

SDL trace (can be viewed in text or XML format)

Syslog

Cisco RIS Data Collector

See Table 7-1 for a description of the alarm monitors.

Table 7-1 Alarm Destinations 

Name
Destination description

Enable Alarm for Event Viewer

Windows 2000 Event Viewer program. The program logs Cisco Unified CallManager errors in the Application Logs within Event Viewer and provides a description of the alarm and a recommended action.

Enable Alarm for SDI Trace

The SDI trace library. Ensure this alarm destination is configured in Trace configuration of Cisco Unified CallManager Serviceability.

Enable Alarm for Syslog

The Syslog file. Check this check box to enable the Syslog messages and configure the Syslog server name. If this destination is enabled and no server name is specified, Cisco Unified CallManager sends Syslog messages to the local host. Default leaves this check box unchecked.

Enable Alarm for SDL Trace

The SDL trace library. This destination applies only to Cisco CallManager and CTIManager services. Configure this alarm destination by using Trace SDL configuration. Refer to the Cisco Unified CallManager Serviceability Administration Guide.

Enable Cisco RIS Data Collector for Event Viewer, Syslog Trace, and SDI Trace

Check these check boxes to enable alarms for errors in the application logs within Event Viewer, the Syslog file, and SDI trace library.


Alarm Filters

Filtering of alarm information occurs based on the alarm event level that was configured for an individual service and the monitor destination. Filtering accomplishes two tasks: helps the administrator narrow the types of alarms that Cisco Unified CallManager collects and prevents the event log, Syslog, and trace files from becoming overloaded. See Table 7-2 for a description of alarm levels.

Table 7-2 Alarm Event Levels 

Name
Description

Emergency

This level designates system as unusable.

Alert

This level indicates that immediate action is needed.

Critical

Cisco Unified CallManager detects a critical condition.

Error

This level signifies that an error condition exists.

Warning

This level indicates that a warning condition is detected.

Notice

This level designates normal but significant condition.

Informational

This level designates information messages only.

Debug

This level designates detailed event information that Cisco TAC engineers use for debugging.


Viewing Alarm Information

You view alarm information to determine whether Cisco Unified CallManager problems exist. Use the Event Viewer program to view alarm information that is sent to the Event Log. You can view alarm information that is sent to the SDI or SDL trace log file in text or XML format. Use Trace to view the SDI or SDL log files in XML format or use a text editor to view the SDI or SDL log files in text format. (Trace supports text format as well.) Use CiscoWorks2000 report viewer to view Syslog messages.

Microsoft Windows 2000 documentation provides detailed information about Event Viewer and Microsoft text editors.

Alarm Definitions

Cisco Unified CallManager stores alarm definitions and recommended actions in a standard query language (SQL) server database. The system administrator can search the database for definitions of all the alarms. The definitions include the alarm name, description, explanation, recommended action, severity, parameters, and monitors. This information aids the administrator in troubleshooting problems that Cisco Unified CallManager encounters. See Table 7-3 for a description of alarm catalogs.

JavaApplications

All Cisco Unified CallManager Java Applications alarm definitions

Note You cannot configure JavaApplications alarms by using the alarm configuration windows. These alarms generally get configured to go to the Event Logs and to generate SNMP traps to integrate with CiscoWorks2000. Use the registry editor that is provided with your operating system to view or change alarm definitions and parameters. If you change your registry entry, you need to restart JavaApplications for the configuration to take effect.

Tip Cisco recommends that you do not change SNMP traps and Catalog configurations.

Applications Using Registry-Based Alarm Interfaces

Editing an Alarm Definition

Alarm Definition Example

Applications Using Registry-Based Alarm Interfaces

The alarm interface library uses the database to get configuration information. A user changes and views configuration parameters and alarm definitions via Cisco Unified CallManager Administration configuration; therefore, only applications that have database access use the alarm interface library to generate alarms. However, applications that use registry-based alarm interfaces, such as all Java-based applications, do not require a separate user interface to allow the user to change the configuration parameters and to view alarm definitions. Instead, users can use the standard XML registry editor that is provided with their operating system to view and change the registry entries. Refer to your online OS documentation for more information on using the registry editor.

Editing an Alarm Definition

Serviceability Alarm Definitions allow administrators to add additional explanation or recommendations for an alarm. All administrators have access to the added information. Administrators directly enter information into the User Defined Text box that displays in the Alarm Details window. Standard horizontal and vertical scroll bars support scrolling. Cisco Unified CallManager Serviceability adds the information to the database.
