Elasticsearch

The system plugin gathers general stats on Elasticsearch nodes.

Configuration:

  [[inputs.elasticsearch]]
  #   ## specify a list of one or more Elasticsearch servers
  #   # 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 elastic search 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 = true
  #
  #   ## Set cluster_health to true when you want to also obtain cluster health stats
  cluster_health = true
  #
  #   ## Adjust cluster_health_level when you want to also obtain detailed health stats
  #   ## The options are
  #   ##  - indices (default)
  #   ##  - cluster
  cluster_health_level = "cluster"
  #
  #   ## Set cluster_stats to true when you want to also obtain cluster stats from the
  #   ## Master node.
  cluster_stats = false
  #
  #   ## node_stats is a list of sub-stats that you want to have gathered. Valid options
  #   ## are "indices", "os", "process", "jvm", "thread_pool", "fs", "transport", "http",
  #   ## "breaker". Per default, all stats are gathered.
  node_stats = ["http", "os", "process", "jvm", "fs", "transport"]
  #
  #   ## Optional TLS Config
  #   # tls_ca = "/etc/njams/ca.pem"
  #   # tls_cert = "/etc/njams/cert.pem"
  #   # tls_key = "/etc/njams/key.pem"
  #   ## Use TLS but skip chain & host verification
  #   # insecure_skip_verify = false
