Queues
In order to store all the logged messages, two queues, #REPLAY_LOG_<replay-log-name> and #REPLAY_TOPICS_<replay-log-name>, are created on every Message VPN that has a replay log.
#REPLAY_LOG_<replay-log-name>- Holds all the logged messages.
-
Messages in this queue are counted towards the Message VPN quota.
#REPLAY_TOPICS_<replay-log-name>- Holds metadata about the logged messages (message ID, time spooled, topic string).
-
Its contents are counted towards the Message VPN quota.
These queues can't be configured through the usual CLI commands associated with queue configuration.
show replay-log
For the replay logs identified in the show replay-log command you can display: the number of messages logged, the space consumed by those messages, the value set for max-spool-usage, and the ingress and egress states.
