Siebel Business Applications Event Logging

Configure event logging for the Siebel Server and server components to monitor the internal operation of Siebel Business Applications. You can specify the type and extent of the information logged for a specific Siebel Server or component event by choosing a log level for the event, for example, you can choose to only log error messages or to log detailed information relating to an event.

Table 7-1 shows Siebel Server and component event log levels. The log level determines the amount of information that is written to the log file and the severity of the event logged. For example, if you set the log level to a low number, then only information relating to the most severe events is logged. If you set the log level to a high number, then less severe events are also logged and more information is written to the log for each event.

Table 7-1 Event Log Levels

Event Log Level	Description
0	Fatal events are logged.
1	Error messages and fatal events are logged.
2	Warning messages are logged in addition to error messages and fatal events.
3	Informational messages are written to the log files in addition to all the messages logged for log levels 0-2.
4	Detailed information is written to the log files for all items logged for log levels 1-3.
5	Diagnostic information is written to the log files as well as all the information logged for log levels 1-4.

Implement the following recommendations when configuring event logging:

• Verify that Siebel Business Applications do not log excessive or sensitive information by default, for example, session IDs.

• In a production environment, do not set event log levels for Siebel Server components to verbose levels; the recommended log levels are 2 (Warnings) or 3 (Informational). Do not log sensitive information at the maximum logging settings.

Event logging is configured using the Siebel Administration - Server Configuration screens or the srvrmgr command-line interface. For detailed information on setting event logging for Siebel Server and server component events, see Siebel System Monitoring and Diagnostics Guide.
