Sentinel raises an event when a monitor item exceeds a predefined outcome (as defined in the process for a test), or when a monitor item reaches a digital state (as defined in the process for a test), during processing.
Depending on the process used by a test, different limit evaluators need to be set up.
For example:
Events for a Digital State Process
A Primary limit is defined. When the monitor item is in the Primary Limit state of the selected state pair, a Primary event is raised, and a Primary state is reached.
An optional Secondary alarm is defined. If the Primary state extends beyond the duration specified for the secondary limit, a Secondary event is raised, and a Secondary state is reached.
An optional Tertiary alarm is defined. If the Secondary state extends beyond the duration specified for the tertiary limit, a Tertiary event is raised, and a Tertiary state is reached.
Events for a Min Max Process
A Max value is defined. When the Max (maximum) is exceeded, a Max Exceeded event is raised, and a Max Exceeded state is reached.
A Min value is defined. When the input value is lower than the Min (minimum) value, a Min Exceeded event is raised, and a Min Exceeded state is reached.
Events for an Alarm Process
A High value is defined. When the High value is exceeded, then a High High Exceeded event is raised, and a High High Exceeded state is reached.
A High value is defined. When the High value is exceeded, a High Exceeded event is raised.
A Low value is defined. When the Low value is exceeded (where the input value is lower than Low value), a Low Exceeded event is raised.
A Low Low value is defined. When the Low Low value is exceeded (where the input value is lower than Low Low value), a Low Low Exceeded event is raised.
If there is no sample data available as an input to the test, a Suppressed event is raised.
Events for a Discrete Min Max Process
A High value is defined. When the High value is exceeded, a High Exceeded event is raised.
A Low value is defined. When the Low value is exceeded (where the input value is lower than Low value), a Low Exceeded event is raised.
Sometimes there is no data at all during a trigger interval. This causes a No Data event.
Events for other Sentinel Processes
Sentinel has a number of plug-in processes available. The events depend on the process used, and are described in the separate Appendix section for that process (for example: Appendix B. Min Max Process contains a section that describes states and events for the Min Max process).
Event Comments
Wherever an event has been raised, it is possible to add an event comment.
Multiple comments can be added to a single event, with the latest one displayed in the main event grid, along with a tally of comments.
Each comment is saved with a time stamp, and the logon identity of the person who added the comment. You can view all of these comments.
Note: In Sentinel, you cannot delete or edit comments.
Editing an Event
Privileges: To edit events, you need a security role that has the Sentinel Events Edit privilege.
Sentinel events can be partially edited. Users with privileges to edit an event can update the state and severity of any Sentinel event. These updates require a comment.
Event Status
An event becomes Invalid if the related case is investigated and then rejected, as part of Case Management. The event status is Valid if the related case is confirmed. For all other case statuses, the event status is Unknown.
Note: An event is only given a status (Unknown, Valid, and Invalid) if Case Management is enabled in Sentinel.
Cases
When an event is raised in Sentinel, a case will also be raised if the test’s states have been configured for Case Management, and if the configured conditions are met.
The Events Grid shows a status for each event, based on the related case (or an Unknown status if there is no related case). If an event has a related case, the event status is Unknown until the case has been investigated. If the case is rejected (case status Rejected) the status becomes Invalid; if the case is confirmed (case status Confirmed), the event status is Valid. Cases are also displayed on the Event Timeline, in the Asset Reports. Cases details can be located using the Case Icon along the bottom of the timeline chart.
