Description

Bind Time (ms)

Time (in milliseconds) taken for the last successful LDAP bind.

Successful Binds

Number of LDAP binds since last reboot.

Writes

The rate that LDAP clients perform write operations, per second.

UDP Operations

The number of UDP operations the LDAP server is processing.

Active Threads

The current number of threads in use by the LDAP subsystem of the local directory service.

Client Sessions

The number of connected LDAP client sessions.

Inbound Updates in Packet

The number of object updates received in the current directory replication updates packets that have not yet been applied to the local server. This counter tells you if the monitored server is receiving changes, and is taking too long to apply them to the database.

Pending Replication Syncs

The number of directory synchronizations that are in queue for this server. This counter identifies replication backlog - the larger the number, the larger the backlog.
