Elasticsearch Integration

  ## Specify a list of one or more Elasticsearch server(s)
  ## you can add username and password to your url to use basic authentication:
  ## servers = ["http://user:pass@localhost:9200"]
  servers = ["http://localhost:9200"]

  ## Timeout for HTTP requests to the Elasticsearch server(s)
  http_timeout = "5s"

  ## When local is true (the default), the node will read only its own stats.
  ## Set local to false when you want to read the node stats from all nodes
  ## of the cluster.
  local = false

  ## Set cluster_health to true when you want to obtain cluster health stats
  cluster_health = true

  ## Adjust cluster_health_level when you want to obtain detailed health stats
  ## The options are
  ##  - indices (default)
  ##  - cluster
  # cluster_health_level = "indices"

  ## Set cluster_stats to true when you want to obtain cluster stats.
  cluster_stats = true

  ## If you set cluster_stats_only_from_master to true, you must also set local to true.
  # cluster_stats_only_from_master = false

  ## Indices to collect; can be one or more index names or _all
  # indices_include = ["_all"]

  ## One of "shards", "cluster", "indices"
  ## Currently only "shards" is implemented
  # indices_level = "shards"

  ## node_stats is a list of sub-stats that you want to collect. Valid options
  ## are "indices", "os", "process", "jvm", "thread_pool", "fs", "transport", "http",
  ## "breaker". By default, all stats are gathered.
  # node_stats = ["jvm", "http"]

  ## HTTP Basic Authentication username and password.
  # username = ""
  # password = ""

  ## 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

  ## Destination field to be used for the mapped value.  By default the source
  ## field is used, overwriting the original value.

  ## Default value to be used for all values not contained in the mapping

  ## match is found.
