Hello @bilbo-the-hobbit

This is because you define the base and not with the good value. Don't define the base, or set the correct entry (like cn=Current,cn=Connections,cn=Monitor for currentconnections). By defaut the script selects the correct base.

But we should indeed return an error code in this case.

Fixed. You should now have this error message:

perl check_ldap_monitor.pl -H ldap://localhost -b cn=monitor -T currentconnections -m greater -w 10 -c 15 -f -vvv           
VERBOSE 3 ===> Enter &get_ldapconn
VERBOSE 2 ===> Connected to ldap://localhost

VERBOSE 3 ===> Leave &get_ldapconn
VERBOSE 3 ===> Enter &get_value
VERBOSE 1 ===> Attribute monitorCounter not found in cn=Monitor
LDAP search failed: Attribute monitorCounter not found.
