This is a quick way to get some basic System information that tells the story of your LDAP system usage. Just use the “ldapsearch” utility with the search base set to one of the below tree structures to get the statistical data.
GET ALL THE DATA (There is a lot!!)
> ldapsearch -h localhost -p 4444 -D "cn=dirmanager" -w 'youldapadminpassword' --useSSL -X -b cn=monitor "(objectclass=*)"
OR JUST GET WHAT YOU NEED!
> ldapsearch -h localhost -p 4444 -D "cn=dirmanager" -w 'youldapadminpassword' --useSSL -X -b "cn=LDAP Connection Handler 0.0.0.0 port 1389 Statistics,cn=monitor" "(objectclass=*)"
