The following table provides a description of the attributes in the cn=Replication Summary monitor entry, dn: cn=Replication Summary <baseDN>,cn=monitor.

Monitor Attribute Description

base-dn:<baseDN>

Base DN summary.

replica: replica-id, ldap-server connected-to, generation-id, replication-backlog, recent-update-rate, peak-update-rate, age-of-oldest- backlog-change

Summary information for each replica in the topology.

This entry appears for each replica in the topology with its own respective properties.

replication-server: server-id, server, generation-id, status, last-connected, last-failed, failed-attempts, attributes.

Summary information for each remote replication server only in the topology.

This entry appears for each Replication Server in the topology with its own respective serverID and server properties.

update-queue: id, max-count, current-count, max-size, current-size, polling-source, polling-source-changed

Summary information for each update queue on a server:

id

The ID of the receiving replica or replication server.

max-count

The maximum number of update messages that the sending replication server will keep in memory for the receiving replica or replication server. If the receiver cannot accept messages fast enough for any reason, such as high load and network latency, then this queue fills up.When that happens, the sending replication server reads update messages from the changelog backend and slows down the update processing considerably.

current-count

The number of update messages currently on the queue that have not been sent to the receiving replica or replication server. Every time the sending replication server sends an update to the receiving replica or replication server, this counter is decremented.

max-size

The maximum total size in bytes of update messages that can be in the queue.This queue is capped by both the max-count and the max-size setting, whichever is reached first.

current-size

The total size of update messages currently on the queue that have not been sent to the receiving replica or replication server. Every time the sending replication server sends an update to the receiving replica or replication server, this value is decremented by the size of the published update message.

polling-source

Set to either memory or db. If set to memory, the sending replication server relies only on the in-memory queue to push update messages to the receiving replica or replication server. If set to db, update messages are read and sorted from the changelog database, which is significantly slower than publishing updates from the in-memory queue.

polling-source-changed

The total number of times the polling-source attribute has changed value either from db to memory or from memory to db.

If this value changes frequently, the queue size setting is too low.
