This process is used for testing discrete data for a monitor item. The sample data is tested against a maximum limit, Max, and a minimum limit, Min.<\/p>\n

The process can be specified to test against Max and Min limits, just against a Max limit, or just against a Min limit. Any periods where no data is found will cause a No Data event.<\/p>\n

State Transition Rules<\/h2>\n

The Discrete Min Max process has clearly defined state transition logic paths. Transition from one state to another is equally dependent on the current evaluation of data, and on the current state.<\/p>\n

State transitions cause events to be raised, allowing for the escalation of actions via the Sentinel framework. Different actions can be assigned to different state outcomes.<\/p>\n

Default to Other States:<\/strong> A Default State can transition to a Min Exceeded State or a Max Exceeded State. If no data is found, the Default State will transition to the No Data State.<\/p>\n

Min Exceeded to Other States: <\/strong>A Min Exceeded State can transition to a Max Exceeded State, or to a Default State. If no data is found, the Min Exceeded State will transition to the No Data State.<\/p>\n

Max Exceeded to Other States:<\/strong> A Max Exceeded State can transition to a Min Exceeded State, or to a Default State. If no data is found, the Max Exceeded State will transition to the No Data State.<\/p>\n

No Data to Other States:<\/strong> As soon as data is found again, the No Data State will transition to another state: this could be Default State, Min Exceeded State or Max Exceeded State.<\/p>\n

\n

Test Outcomes<\/h2>\n

A number of outcomes are possible when the Discrete Min Max process is executed:<\/p>\n\n\n\n\n\n\n\n
Default State<\/strong><\/td>\nData is not in an erroneous state (i.e. the data item is between the minimum and maximum limits).<\/td>\n<\/tr>\n
No Data State<\/strong><\/td>\nNo data found in the trigger interval.<\/td>\n<\/tr>\n
Max Exceeded State<\/strong><\/td>\nData is greater than the maximum limit.<\/td>\n<\/tr>\n
Min Exceeded State<\/strong><\/td>\nData is less than the minimum limit.<\/td>\n<\/tr>\n
Suppressed State<\/strong><\/td>\nThe monitor has been suppressed. For example, if the precondition has not been met.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
\n

Conditional Logic<\/h2>\n

The Discrete Min Max process provides the following conditional logic.<\/p>\n

Min Limit Monitoring<\/h3>\n

The monitor item is monitored for a minimum limit only.<\/p>\n

If the item value exceeds the value defined in Min, a min exceeded event occurs and a min exceeded state is reached.<\/p>\n

The Min limit must be defined as a fixed numerical value.<\/p>\n\n\n\n
<\/td>\n\u00a0Data Item
\n\u00a0Min Limit
\n\u00a0Trigger Interval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The following events are depicted in the graph:<\/p>\n\n\n\n\n\n\n
<\/td>\nThe data value is now below the min limit and a min exceeded state is reached. A min exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nAt the next trigger interval, the data is no longer lower than the min limit. It has returned to the default state. A new default<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the same trigger interval, the data item value is lower than the min limit again. A min exceeded state is reached, and a min exceeded <\/strong>event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next trigger interval, the data value is no longer lower than the min limit. A default state is reached, and a default <\/strong>event is raised.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Max Limit Monitoring<\/h3>\n

The monitor item is monitored for a maximum limit only.<\/p>\n

If the item value exceeds the value defined in Max, a max exceeded event occurs and a max exceeded state is reached.<\/p>\n

The Max limit must be defined as a fixed numerical value.<\/p>\n\n\n\n
<\/td>\n\u00a0Data Item
\n\u00a0Max Limit
\n\u00a0Trigger Interval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The following events are depicted in the graph:<\/p>\n\n\n\n\n\n\n\n
<\/td>\nIn this interval, the data item value is greater than the max limit. A max exceeded state is reached, and a max exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next interval, the data item value is no longer greater than the max limit. A default state is reached, and a default<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next interval, the data item value is greater than the max limit. A max exceeded state is reached, and a max exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the same trigger interval, the data value is no longer lower than the min limit. A default state is reached, and a default <\/strong>event is raised.<\/td>\n<\/tr>\n
<\/td>\nNo data found in the trigger interval. A no data<\/strong> event is raised.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Min and Max Limit Monitoring<\/h3>\n

Here the item is monitored for minimum and for maximum limits on entities.<\/p>\n

If the item value exceeds Max, then a max exceeded state is reached. If the value is lower than min, then a min exceeded state is reached.<\/p>\n

In the following example, Discrete Minimum and Maximum Monitoring is used to detect when a discrete value is greater than the maximum limit, and when a discrete value is less than the minimum limit.<\/p>\n

The Min and Max limits must be defined as fixed numerical values.<\/p>\n\n\n\n
<\/td>\n\u00a0Data Item
\n\u00a0Max Limit
\n\u00a0Min Limit
\n\u00a0Trigger Interval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The following events are depicted in the graph:<\/p>\n\n\n\n\n\n\n\n
<\/td>\nIn this interval, the data item value is greater than the max limit. A max exceeded state is reached, and a max exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next interval, the data item value is no longer greater than the max limit. A default state is reached, and a default <\/strong>event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next interval, the data item value is less than the min limit. A min exceeded state is reached, and a min exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the same trigger interval, the data value is no longer lower than the min limit. A default state is reached, and a default <\/strong>event is raised.<\/td>\n<\/tr>\n
<\/td>\nNo data found in the trigger interval. A no data<\/strong> event is raised.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

No Data Events<\/h3>\n

The Discrete Min Max process tests discrete data. Sometimes there is no data at all during a trigger interval. This causes a No Data<\/strong> event.<\/p>\n

In this example, the data is monitored for a maximum limit only.<\/p>\n\n\n\n
<\/td>\n\u00a0Data Item
\n\u00a0Max Limit
\n\u00a0Trigger Interval<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The following events are depicted in the graph:<\/p>\n\n\n\n\n\n
<\/td>\nIn this interval, the data item value is greater than the max limit. A max exceeded state is reached, and a max exceeded<\/strong> event is raised.<\/td>\n<\/tr>\n
<\/td>\nIn the next interval, the data item value is no longer greater than the max limit. A default state is reached, and a default <\/strong>event is raised.<\/td>\n<\/tr>\n
<\/td>\nNo data found in the trigger interval. A no data<\/strong> event is raised.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
