HAProxy Input Plugin

The HAProxy input plugin gathers statistics using the stats socket or HTTP statistics page of a HAProxy server.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read metrics of HAProxy, via stats socket or http endpoints
[[inputs.haproxy]]
  ## List of stats endpoints. Metrics can be collected from both http and socket
  ## endpoints. Examples of valid endpoints:
  ##   - http://myhaproxy.com:1936/haproxy?stats
  ##   - https://myhaproxy.com:8000/stats
  ##   - socket:/run/haproxy/admin.sock
  ##   - /run/haproxy/*.sock
  ##   - tcp://127.0.0.1:1936
  ##
  ## Server addresses not starting with 'http://', 'https://', 'tcp://' will be
  ## treated as possible sockets. When specifying local socket, glob patterns are
  ## supported.
  servers = ["http://myhaproxy.com:1936/haproxy?stats"]

  ## By default, some of the fields are renamed from what haproxy calls them.
  ## Setting this option to true results in the plugin keeping the original
  ## field names.
  # keep_field_names = false

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false
HAProxy Configuration

The following information may be useful when getting started, but please consult the HAProxy documentation for complete and up to date instructions.

The stats enable option can be used to add unauthenticated access over HTTP using the default settings. To enable the unix socket begin by reading about the stats socket option.

servers

Server addresses must explicitly start with 'http' if you wish to use HAProxy status page. Otherwise, addresses will be assumed to be an UNIX socket and any protocol (if present) will be discarded.

When using socket names, wildcard expansion is supported so plugin can gather stats from multiple sockets at once.

To use HTTP Basic Auth add the username and password in the userinfo section of the URL: http://user:password@1.2.3.4/haproxy?stats. The credentials are sent via the Authorization header and not using the request URL.

keep_field_names

By default, some of the fields are renamed from what haproxy calls them. Setting the keep_field_names parameter to true will result in the plugin keeping the original field names.

The following renames are made:

  • pxname -> proxy
  • svname -> sv
  • act -> active_servers
  • bck -> backup_servers
  • cli_abrt -> cli_abort
  • srv_abrt -> srv_abort
  • hrsp_1xx -> http_response.1xx
  • hrsp_2xx -> http_response.2xx
  • hrsp_3xx -> http_response.3xx
  • hrsp_4xx -> http_response.4xx
  • hrsp_5xx -> http_response.5xx
  • hrsp_other -> http_response.other
