HAProxy 和 Datadog 集成

[[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

[[outputs.datadog]]
  ## Datadog API key
  apikey = "my-secret-key"

  ## Connection timeout.
  # timeout = "5s"

  ## Write URL override; useful for debugging.
  ## This plugin only supports the v1 API currently due to the authentication
  ## method used.
  # url = "https://app.datadoghq.com/api/v1/series"

  ## Set http_proxy
  # use_system_proxy = false
  # http_proxy_url = "http://localhost:8888"

  ## Override the default (none) compression used to send data.
  ## Supports: "zlib", "none"
  # compression = "none"

  ## When non-zero, converts count metrics submitted by inputs.statsd
  ## into rate, while dividing the metric value by this number.
  ## Note that in order for metrics to be submitted simultaenously alongside
  ## a Datadog agent, rate_interval has to match the interval used by the
  ## agent - which defaults to 10s
  # rate_interval = 0s
