event traces. Cisco CallManager and CiscoWorks2000 provide this functionality
for unified message logging, display, and management. The following are the two
main components to the system logging mechanism:
• Syslog Collector, which resides on Cisco CallManager
• Syslog Receiver (The CiscoWorks2000 server can also function as a receiver,
as described in the “Syslog Administrative Interface” section on page 11-6.)
Syslog Collector
A Syslog Analyzer Collector (SAC) program runs as a Windows NT service on
the Cisco CallManager server or any processing node in the network. The SAC
program uses a configuration (.ini) file to set the environment variables such as
the CiscoWorks2000 hostname and other parameters. This configuration file,
SAenvProperties.ini, and its directory path are specified in the Windows NT
registry, and the Cisco CallManager installation program sets their values. During
startup time, the SAC tries to check in with the CiscoWorks2000 server to get
some configuration and message filter information using a Common Object
Request Broker Architecture (CORBA) method call. Then, it sends an
initialization message that consists of the SAC hostname, the name of the syslog
file, and other information for CiscoWorks2000 to keep track of it.
During normal operation, SAC reads messages from User Datagram Protocol
(UDP) port 514. When it receives new messages, SAC processes the messages
(for example, by performing filtering and time zone conversions) and then sends
them to the CiscoWorks2000 server for storage and analysis. SAC also sends a
status or statistic message periodically to the CiscoWorks2000 server. Figure 11-1
illustrates the interoperability of CiscoWorks2000 and Cisco CallManager.
