Agent uses a HTTP check if the service listen on port 3128.

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 Squid running outside a container
  - type: "squid"
    address: "127.0.0.1"
    port: 3128
    http_path: "/"   # This is the path used for availability check, not metrics gathering.
    http_host: "127.0.0.1:80"   # Host header sent. Like other option, you can omit them and default value will be used.

  # For an additional Squid running outside a container
  - type: "squid"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 3129
    http_path: "/"   # This is the path used for availability check, not metrics gathering.
    http_host: "127.0.0.1:81"   # Host header sent. Like other option, you can omit them and default value will be used.

  # For a Squid running in a Docker container
  - type: "squid"
    instance: "CONTAINER_NAME"
    address: "172.17.0.2"
    port: 3128
    http_path: "/"   # This is the path used for availability check, not metrics gathering.
    http_host: "127.0.0.1:80"   # Host header sent. Like other option, you can omit them and default value will be used.

When using Docker, you may use Docker labels to set http_path and http_host:

docker run --label glouton.http_path="/readiness" --label glouton.http_host="my-host" [...]

Only the metric from service check is produced:
