Event queue controls contain information about each event queue. Each user's event queue has its own set of event queue controls. The IXLLIST REQUEST=READ_EQCONTROLS request allows you to read your event queue's controls. Event queue control information includes the following:

• Vector index associated with the monitored event queue
• Number of event monitor controls that are currently queued to the event queue
• Approximate number of empty to nonempty event queue transitions that have occurred
• Indicator as to whether the user wants the list transition exit (identified by the LISTTRANEXIT keyword on IXLCONN) given control when the event queue transitions from empty to nonempty
• Indicator as to whether the user is currently monitoring the event queue
