Openldap Input Plugin

This plugin gathers metrics from OpenLDAP's cn=Monitor backend.

Configuration:

To use this plugin you must enable the monitoring backend.

[[inputs.openldap]]
  host = "localhost"
  port = 389

  # ldaps, starttls, or no encryption. default is an empty string, disabling all encryption.
  # note that port will likely need to be changed to 636 for ldaps
  # valid options: "" | "starttls" | "ldaps"
  ssl = ""

  # skip peer certificate verification. Default is false.
  insecure_skip_verify = false

  # Path to PEM-encoded Root certificate to use to verify server certificate
  ssl_ca = "/etc/ssl/certs.pem"

  # dn/password to bind with. If bind_dn is empty, an anonymous bind is performed.
  bind_dn = ""
  bind_password = ""

Measurements & Fields:

All monitorCounter, monitorOpInitiated, and monitorOpCompleted attributes are gathered based on this LDAP query:

(|(objectClass=monitorCounterObject)(objectClass=monitorOperation))

Metric names are based on their entry DN.

Metrics for the monitorOp* attributes have _initiated and _completed added to the base name.

An OpenLDAP 2.4 server will provide these metrics:

• openldap
  • max_file_descriptors_connections
  • current_connections
  • total_connections
  • abandon_operations_completed
  • abandon_operations_initiated
  • add_operations_completed
  • add_operations_initiated
  • bind_operations_completed
  • bind_operations_initiated
  • compare_operations_completed
  • compare_operations_initiated
  • delete_operations_completed
  • delete_operations_initiated
  • extended_operations_completed
  • extended_operations_initiated
  • modify_operations_completed
  • modify_operations_initiated
  • modrdn_operations_completed
  • modrdn_operations_initiated
  • search_operations_completed
  • search_operations_initiated
  • unbind_operations_completed
  • unbind_operations_initiated
  • bytes_statistics
  • entries_statistics
  • pdu_statistics
  • referrals_statistics
  • read_waiters
  • write_waiters

Tags:

• server= # value from config
• port= # value from config
