Specifies the health level at which a
ciscoHealthMonitorHealthLevel notification will be
generated for the specified subsystem and entity.
A notification will only be generated if the health
level had previously reached the low threshold level
prior to reaching this high threshold level.
Health levels oscillating within the high and the low
threshold levels do not generate notifications.
A health level going from low threshold (or below)
to high threshold (or above) represents a return
to normal health for the specified subsystem.
Set your optimal health level to this threshold.
