ccvpEventState
Cisco Customer Voice Portal Event State
1.3.6.1.4.1.9.9.590.1.7.5
The event state object identifies the state (not to be confused with severity) of the notification and potentially the current state of the functional component that generated the notification. The possible states are: 'raise': A raise state identifies a notification received as a result of a health-impacting condition, such as a process failure. A subsequent clear state notification will follow when the error condition is resolved. 'clear': The clear state indicates that the condition which generated a previous raise notification has been resolved.
