The PingDirectoryProxy Server exposes a majority of its information under the cn=monitor entry. You can access these entries over LDAP using the ldapsearch tool.
$ bin/ldapsearch --hostname server1.example.com --port 1389 \ 
  --bindDN "uid=admin,dc=example,dc=com" --bindPassword secret \ 
  --baseDN "cn=monitor" "(objectclass=*)"
