A timestamp, such as [05/Jan/2009:02:27:22 -0500], although the format varies depending
on the platform. The ending four digits, -0500, indicate the time difference in relation to GMT.
The plug-in being called, for internal operations.
Functions called by the plug-in, for internal operations.
Messages returned by the plug-in or operation, which may include LDAP error codes, connection
information, or entry information.

Frequently, the messages for an operation appear on multiple lines of the log, but these are not
identified with a connection number or operation number.

Example 5.3, “Error Log Excerpt”

shows excerpts from an error log at the default logging level, which

includes some task information, critical errors, and server startup messages.

5.2.3. Error Log Content for Other Log Levels

The different log levels return not only different levels of detail, but also information about different types
of server operations. Some of these are summarized here, but there are many more combinations of
logging levels possible.

Replication logging is one of the most important diagnostic levels to implement. This logging level
records all operations related to replication and Windows synchronization, including processing
modifications on a supplier and writing them to the changelog, sending updates, and changing replication
agreements.

Whenever a replication update is prepared or sent, the error log identifies the replication or
synchronization agreement being specified, the consumer host and port, and the current replication task.

[timestamp] NSMMReplicationPlugin - agmt="name" (consumer_host:consumer_port):
current_task

For example:

[09/Jan/2009:13:44:48 -0500] NSMMReplicationPlugin - agmt="cn=example2"
(alt:13864): {replicageneration} 4949df6e000000010000

{replicageneration} means that the new information is being sent, and
4 94 9df6e000000010000 is the change sequence number of the entry being replicated.

Example 5.4, “Replication Error Log Entry”

shows the complete process of sending a single entry to a

consumer, from adding the entry to the changelog to releasing the consumer after replication is
complete.
