The current operational status of the system as a whole. A
value 'unknown(1)' indicates that the current state of the
system could not be determined. The value 'running(2)'
indicates that the system is up and running and that no
unusual error conditions are known. The 'warning(3)' state
indicates that agent has been informed of an unusual error
condition by the operational software (e.g., a device driver)
but that the system is still 'operational'. (The
xsysBootDiagsCode object may provide more information.) A
value of 'testing(4)', indicates that the system is not
available for use because it is in the testing state. The
state of 'down(5)' is used only when the agent has been
informed that the system is not available for any use. (How it
can tell you it's down is an interesting question.)
