System event log

There are three types of the system event log.

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).
