This object indicates the state (not to be confused with
severity) of the event and potentially the current status of
the functional component that generated the event. The
possible states are:
'raise': A raise state identifies an event received as a
result of a health-impacting condition, such as a
process failure. A subsequent clear state event
will follow when the error condition is resolved.
A node which generates a 'raise' state event may
be impaired and likely requires the attention of
an administrator.
'clear': The clear state indicates that the condition
which generated a previous raise notification has
been resolved. This may occur automatically with
fault-tolerant deployments or may be the result
of administrator intervention.
