Logs

To enable metrics gathering, Bleemeo agent needs access to HAProxy stats page and to know where it may find this page.

On HAProxy side, you will need to enable statistics page on a HTTP(S) frontend, for example:

frontend api-http
    bind 0.0.0.0:80
    stats enable
    stats uri     /statistics

On Bleemeo agent side, you need configure check by adding the following to /etc/glouton/conf.d/99-local.conf:

service:
  [...]

  # For a HAProxy running outside a container
  - type: "haproxy"
    address: "127.0.0.1"
    port: 80
    stats_url: "http://my-server/statistics"
    # For authenticated access, use
    # stats_url: "http://username:password@my-server/statistics"

  - type: "haproxy"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 81
    stats_url: "http://my-server:81/statistics"
    # For authenticated access, use
    # stats_url: "http://username:password@my-server:81/statistics"

  # For a HAProxy running in a Docker container
  - type: "haproxy"
    instance: "CONTAINER_NAME"
    address: "127.0.0.1"
    port: 80
    stats_url: "http://my-server/statistics"
    # For authenticated access, use
    # stats_url: "http://username:password@my-server/statistics"
