System event log
The system event log contains messages of three types:
Information
Information messages do not require action; they record significant
system-level events, such as when the server is started.
Warning
Warning messages do not require immediate action; they indicate possible
problems, such as when the recommended maximum ambient temperature
is exceeded.
Error Error messages might require action; they indicate system errors, such as
when a fan is not detected.
Each message contains date and time information, and it indicates the source of
the message (POST or the IMM).
