I don't know much about cn=monitor,cn=config, but I would first look at the format of your LDIF file.
You only use a dash (-) to separate multiple changes on the same previously defined DN (dn: cn=module,cn=config).
If you change the target of modifications to a different DN (dn: olcDatabase=monitor,cn=config) then you separate it by a blank line, not a dash.
You seem to be doing parts of both.Try removing the dash or remove the blank line, the "dn: olcDatabase=monitor,cn=config" and the "changetype: add" lines, depending on what you were trying to do.
An example of multiple DN targets within one LDIF file can be found in provider_sync.ldif listed in the LDAP Replication section of https://help.ubuntu.com/10.04/serverguide/C/openldap-server.html

The openldap guide suggests that the configuration for dynamic configuration is yet to be written and it seems it is probably easy to get configured from the start but not intuitive enough for me to add to an already running server.
(this is my consumer if that makes a difference)
# cat monitor-add.ldif # Load dynamic backend modules dn: cn=module,cn=config changetype: add add: module olcModuleload: back_monitor -
# http://www.openldap.org/doc/admin24/monitoringslapd.html dn: olcDatabase=monitor,cn=config #objectClass: olcDatabaseConfig changetype: add add: olcDatabase olcDatabase: {2}monitor
# ./monitor-add.sh Enter LDAP Password: adding new entry "cn=module,cn=config" ldapmodify: update failed: cn=module,cn=config ldap_add: Bad parameter to an ldap routine (-9)
I can't seem to find the right ldif combination to add monitor (Ubuntu Lucid / slapd 2.4.21-0ubuntu5.5)
# grep ModulePath /etc/ldap/slapd.d/cn=config/cn=module{0}.ldif olcModulePath: /usr/lib/ldap
