Event Properties ReferenceProvides a reference for start and end events.Leave FeedbackIntroductionA start event defines how a process starts and an end event defines how a process completes. The types of start events:Signal start eventTimer start eventSignal start eventA signal start event runs processes when a specific event is triggered. For example, a signal start event occurs when an alert is created from a certain metric with a critical state. The symbol for a signal is a circle with a triangle:Signal start event propertiesThe following table describes how to configure a signal start event:Signal Start Event PropertiesPropertyDescriptionNameRefers to name of the event.IdRefers to a unique identifier of the event. The ID is system generated and any manual modification to the ID is not allowed.ConfigurationRefers to a specific platform event for the start event to run. For example, if an alert is created from a particular resource, then the start event becomes active and starts the process.Filter CriteriaRefers to a condition that enables a signal start event to run.Setting conditions for signal start eventsThe filter criteria uses a nested set of alert/resource attributes to define a condition that enables a signal start event to run.To add a conditional expression for a signal start event:From the Filter Criteria box, type $ followed by an alert or resource attribute.For example, select Alert in the Configuration section, then its alert attributes appear in the drop-down.Provide a space after the attribute and select a relational operator to define the relationship between the left and right items.Provide a value.For example, a completed sample condition can be: $currentState = "CRITICAL" AND $repeatCount > 5NotesFor strings, enclose it with double-quotes ("<string>"). Example: "Critical". A green color tick mark appears if the logical expression is in the right format.For Alert Created or Resource Created options, there are no relational operator restrictions. If Alert Updated option is selected, the conditional expression must contain one of these relational operators: IS, WAS, or CHANGED.Timer start eventA timer start event runs processes based on a schedule that includes start time with a recurrence schedule. For example, a process can run every on the first Monday of every month at 9 AM.

Supported end types are:Never: Refers to never ending the event.After Occurrences: Refers to ending the event after occurring for a certain number of times.On: Refers to ending an event on a certain date.Recurrence Pattern: Recurrence of the event can occur by Minute, Hourly, Daily, Weekly, and Monthly.Repeat Every: Refers to how often the event must repeat.Example: A start event can run for every 2 daysEnd eventAn end event indicates the completion of a workflow with these characteristics:A workflow must end with an end eventThe end event does not contain any outgoing sequence flowsThe symbol for an end event is a circle with a bold border:What to do nextSee Gateway Overview.See Managing Process Definitions.
