Metrics

Logs

To enable metrics gathering, you need to enable the slapd monitoring backend, and to set a bind CN and password in the agent configuration so it can access the metrics.

If some auto-detected parameters are wrong or you want to configure metric gathering, you can add the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]
  # For an OpenLDAP running outside a container
  - type: "openldap"
    address: "127.0.0.1"
    port: 389
    # dn/password to bind with. If username is empty, an anonymous bind is performed.
    username: "cn=admin,dc=example,dc=org"
    password: "adminpassword"
    # Use ldaps, note that port will likely need to be changed to 636.
    ssl: true
    # Use StartTLS (note that you can't enable both ssl and starttls at the same time).
    starttls: true
    # Don't verify host certificate.
    ssl_insecure: true
    # Path to PEM-encoded Root certificate to use to verify the server certificate.
    ca_file: "/myca"

  # For an additional OpenLDAP running outside a container
  - type: "openldap"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 390
    username: "cn=admin,dc=example,dc=org"
    password: "adminpassword"

  # For an OpenLdap running in a Docker container
  - type: "openldap"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 389
    username: "cn=admin,dc=example,dc=org"
    password: "adminpassword"
