0.19.1: Message events
Message events are generated by IBM WebSphere Application Server
code in response to system events occurring in the application server
environment. They are always collected. The administrator can decide
whether to look at them.
Message events include, in order of increasing severity:
- Audit
- Indicates a significant event that must be recorded. Are shown when audit messages
are enabled.
- Terminate
- Indicates that a process has terminated normally (a 0 is returned to the shell).
- Warning
- Indicates that a problem has occurred that must be fixed to prevent a more serious
problem. Are shown when warning messages are enabled.
- Error
- Indicates that a severe error occurred, but did not cause processing to terminate
- Fatal
- Indicates that a process has encountered a fatal error and has terminated abnormally.
When a process terminates in this way, the trace service writes its internal
ring buffer to the Serious Error file and returns a -1 to the shell.
