LDAP service monitoring
The NetScaler appliance has one built-in monitor that can be used to monitor LDAP services: the LDAP monitor. It periodically checks the LDAP service to which it is bound by authenticating and sending a search query to it. If the search is successful, the service is marked UP. If the LDAP server does not locate the entry, a failure message is sent to the LDAP monitor, and the service is marked DOWN.
Configure the LDAP monitor to define the search that it must perform when sending a query. You can use the Base DN parameter to specify a location in the directory hierarchy where the LDAP server must start the test query. You can use the Attribute parameter to specify an attribute of the target entity.
Note: Monitor probes originate from the NSIP address.
| Parameter | Specifies |
|---|---|
| baseDN | Base name for the LDAP monitor from where the LDAP search must start. If the LDAP server is running locally, the default value of base is dc=netscaler, dc=com. |
| bindDN | BDN name for the LDAP monitor. |
| filter | Filter for the LDAP monitor. Use the filter parameter in a query to limit the number of results. If you do not specify this parameter in the query, the filter applies for the entire object class, which might be a costly operation, such as a high CPU usage. |
| password | Password used in monitoring LDAP servers. |
| attribute | Attribute for the LDAP monitor. |
To configure the built-in LDAP monitor, see Configuring Monitors in a Load Balancing Setup.
