By default, the Directory Proxy Server has two health check instances enabled for use on all servers:
  • Consume Admin Alerts. This health check detects administrative alerts from the Directory Server, as soon as they are issued, by maintaining an LDAP persistent search for changes within the cn=alerts branch of the Directory Server. When the Directory Proxy Server is notified by the Directory Server of a new alert, it immediately retrieves the base cn=monitor entry of the Directory Server. If this entry has a value for the unavailable-alert-type attribute, then the Directory Proxy Server will consider it unavailable. If this entry has a value for the degraded-alert-type attribute, then the Directory Proxy Server will consider it degraded.

  • Get Root DSE. This health check detects if the root DSE entry exists on the LDAP external server. As this entry always exists on a PingDirectory Server, the absence of the entry suggests that the LDAP external server may be degraded or unavailable.
