When an event occurs, the severity level of the event (as defined by the event subtype) is compared with the log level of the event type. If the numerical value of the event severity level is equal to or lower than the numerical value of the event type log level, then the event is written to the log file. If the numerical value of the event severity level is higher than the numerical value of the event type log level, then the event is ignored.
NOTE: Event subtypes with a lower numeric value have a higher severity. For example a value of 0 indicates the event subtype is more severe than one with a value of 5. By setting the event log level to a low number such as 1, only the most severe events are logged, but if the event log level is set to a higher number such as 5, more information is captured including less severe event subtypes.
For example, the Siebel Server components in the Enterprise Application Integration component group (alias EAI) have an event type called EAI Siebel Wizard. Several event subtypes belong to the EAI Siebel Wizard event type, including:
While the EAI component group is running, the process encounters a multi-value group (MVG). This encounter creates an event of the EAI Siebel Wizard MVG subtype. If the MVG is invalid, a second event of the EAI Siebel Wizard Invalid MVG subtype is created. If the log level of the EAI Siebel Wizard event type is set to 1, both events are ignored. If the log level is set to 3, both events are written to the log file.
Events are logged at the Siebel Server level and the component level. See Configuring Siebel Server Logging for details on Siebel Server events; see Configuring Siebel Server Component Logging for information on component events.
