VENT MONITORING
ADU Event Monitoring
This chapter describes the events that are sent by the ADU Server. This chapter also explains how
to assign a request on behalf of a client and how to establish monitoring criteria. The ADU Server
continuously monitors the contents of ADUs for changes, and reports those changes to interested
clients through event messages.
Clients register their interest in ADUs by assigning to the ADU Server with a monitoring criteria,
which is a specification describing the condition that should generate an event notice. For
example, a client might request notification when an agent enters wrapup state, or when an ADU is
terminated. The client receives event messages about ADUs that match the specification, and
continues to receive all events generated for those ADUs for as long as they match the client's
monitoring criteria.
The ADU Server generates seven types of events that describe changes to existing ADUs. The
following table lists the events and the contents of the event messages written in the ADU and sent
to monitoring clients.
Event Description Message
ADU.change A modification has occurred in a monitored
ADU.
All affected {name, value}
couples and the ADUID.
ADU.delete Values have been deleted from the ADU. All deleted values.
ADU.drop The ADU has changed and no longer
matches the assign criteria. It will no
longer be monitored. If the ADU later
changes so that it again meets the assign
criteria, the client gets an ADU.watch
event.
The ADUID.
