Agent uses a Memcached check if the service listen on port 11211.

If some auto-detected parameters are wrong, you can manually override them by adding the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]

  # For a Memcached running outside a container
  - type: "memcached"
    address: "127.0.0.1"
    port: 11211

  # For a Memcached running outside a container
  - type: "memcached"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 11212

  # For a Memcached running in a Docker container
  - type: "memcached"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 11211
