Events Event are special records the system uses to log when certain conditions occur and to take some kind of action in response to the conditions. The system uses business rules to monitor for system conditions and to generate event records in the Event [sysevent] table, which is also known as the event log or event queue. Event-generating business rules typically use this script logic: If [some condition is true for the current record], then [add a specific event to the queue]. For example, here are some of the conditions in the incident event business rule: If a user adds a comment to an incident record, add an incident.commented event. If a user adds an incident record, add an incident.inserted event. If a user updates an incident record, add an incident.updated event. Event-generating business rules use the GlideSystem eventQueue method to insert event records, which typically contain this information:Table 1. Event fields Field Description Name The unique name of event. Baseline event names include the record effected and the triggering action such as incident.commented. Parm1 An event-specific parameter the system uses to pass record information to other parts of the system, such as a record Sys ID or a field value. Parm2 Another event-specific parameter the system uses to pass record information to other parts of the system, such as a record Sys ID or a field value. Table The table to which the event applies. This is the same table on which the business rule ran. Instance The Sys ID of the record to which this event applies. Scheduled jobs periodically read the event queue and forward them to the appropriate handler for processing. The handler uses information from event records to take some kind of action such as: Run a script action Schedule a job Send a notification Trigger a workflow activity Trigger an inactivity monitor By default, the system provides events covering a broad view of application activity. If existing events do not meet your needs, you can create your own events to watch for specific changes to records.
