By default, the PingDirectoryProxy server has two health check instances enabled for use on all servers:
- Consume Admin Alerts. This health check detects administrative alerts from the
PingDirectory server, as soon as they are issued, by
maintaining an LDAP persistent search for changes within the
cn=alertsbranch of the PingDirectory server. When the PingDirectoryProxy server is notified by the PingDirectory server of a new alert, it immediately retrieves the base
cn=monitorentry of the PingDirectory server. If this entry has a value for the
unavailable-alert-typeattribute, then the PingDirectoryProxy server will consider it unavailable. If this entry has a value for the
degraded-alert-typeattribute, then the PingDirectoryProxy server will consider it degraded.
- Get Root DSE. This health check detects if the root DSE entry exists on the LDAP external server. Since this entry always exists on a PingDirectory server, the absence of the entry suggests that the LDAP external server could be degraded or unavailable.
