Event Triggers
This defines a list of Event Triggers.
Field Description | Field Name | |
Context Mask. This mask is resolved during trigger processing. If the event specified by the Event parameter is fired in any context matching this mask, the trigger activates an alert. In most cases, this context mask points to one explicit context, being a context path, rather than a mask. | mask | |
Event. Name of the event to be monitored. | event | |
Filter Expression. An Iotellect Expression which must evaluate to TRUE to activate the trigger. May contain references to the cells in the Data Table associated with the Event. | filter | |
Record Key Expression. Iotellect Expression used to define a key (usually it is a certain field of Event's data table) when Event's data table has several records and they must be checked row by row. | recordKeyExpression | |

Standard variables only. | ||
Level. Level of this alert event. In addition to the fixed values, may be set to Same As Event (this is a default setting). In this case level of alert event will be same as level of event that caused the alert. | level | |
Deactivation Event. Name of the deactivation event. Deactivation event firing will deactivate the trigger if an expression defined in the Deactivation Expression will be TRUE. | correlated | |
Deactivation Expression. An Iotellect Expression which must evaluate to TRUE to deactivate the trigger when event defined in the Deactivation Event occur. May contain references to the cells in the Data Table associated with the event defined in the Deactivation Event. | correlator | |
Count. Count of events which must occur during the Period to activate or deactivate trigger. By default, a single event will do that. | count | |
Period. Period of time within events must occur to activate or deactivate trigger. Applicable only if Count is greater than 1. | period | |
Trigger Message. Trigger message is usually used to indicate the root cause of alert. This is an expression so static messages should be quoted (e.g. | message | |
