About the default health checks

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=alerts branch of the PingDirectory server. When the PingDirectoryProxy server is notified by the PingDirectory server of a new alert, it immediately retrieves the base cn=monitor entry of the PingDirectory server. If this entry has a value for the unavailable-alert-type attribute, then the PingDirectoryProxy server will consider it unavailable. If this entry has a value for the degraded-alert-type attribute, 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.
