Event Properties ReferenceProvides a reference for start and end events.Leave FeedbackIntroductionStart events define how a process starts and end event define 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 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.Example: CriticalExample alert condition: $currentState = "critical"NotesFor strings, enclose it with double-quotes ("<string>")For example, "Critical". A green color tick mark appears to indicate the logical expression is in the right format. Example conditional expression: *$currentState = "CRITICAL" AND $repeatCount > 5*.For Alert Created or Resource Created options, there are no relational operator restrictions. But, 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.

The ID is system generated and any manual modification to the ID is not allowed.ConfigurationRefers to a schedule to start the event.Start Date: Refers to the start date of the event based on the customized Time zone settings.Ends: Refers to the end time of the event. 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 borderWhat to do nextSee Gateway Overview.See Managing Process Automation.
