Kapacitor Plugin

The Kapacitor plugin will collect metrics from the given Kapacitor instances.

Configuration:

[[inputs.kapacitor]]
  ## Multiple URLs from which to read Kapacitor-formatted JSON
  ## Default is "http://localhost:9092/kapacitor/v1/debug/vars".
  urls = [
    "http://localhost:9092/kapacitor/v1/debug/vars"
  ]

  ## Time limit for http requests
  timeout = "5s"

  ## 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
