How HAD deletes messages

The VCS engine, HAD, stores messages to be sent to notifier. HAD deletes messages under the following conditions:

• The message has been in the queue for one hour and notifier is unable to deliver the message to the recipient. (This behavior means that until notifier connects to HAD, messages are stored permanently in the queue until one of the following conditions are met.)

  or

• The message queue is full and to make room for the latest message, the earliest message is deleted.

  or

• VCS receives a message acknowledgement from notifier when notifier has delivered the message to at least one designated recipient.

  Example: two SNMP consoles and two email recipients are designated. Notifier sends an acknowledgement to VCS, even if the message reached only one of the four recipients. Error messages are also printed to the log files when delivery errors occur.
