LDAP response time


This Cacti script measures LDAP response times on 3 operations:

  • A bind

  • A search on the RootDSE

  • A search on a naming context

Here is a generated graph example:

This plugin, along with all other Nagios plugins from this site, can be downloaded in a single archive.


You have to copy the perl script in Cacti scripts directory (for example /usr/share/cacti/site/scripts/ on Debian):

$ cp ldap_response_time.pl /usr/share/cacti/site/scripts/

Then go on Cacti administration panel and choose “Import template”. Select the XML local file shipped with the script and “save”.


You can edit the values of command line parameters by modifying the Data source template.

Choose “Data Templates” and click on “LDAP - response time”. You can see at the bottom the “Custom Data” table. Parameters are:

  • Host or IP

  • Port

  • Connection account: anonymous bind if not defined

  • Connection password

  • Timeout

  • LDAP protocol version

  • Suffix: “auto” means the script will discover the naming context from the rootDSE. You can also specify one naming context here (for example “dc=example,dc=com”), or use “none” to disable searching on the suffix (useful for LDAP proxies).
