# Elasticsearch Input Plugin

The [elasticsearch](https://www.elastic.co/) plugin queries endpoints to obtain
[Node Stats][1] and optionally [Cluster-Health][2] metrics.

In addition, the following optional queries are only made by the master node:
 [Cluster Stats][3] [Indices Stats][4] [Shard Stats][5]

Specific Elasticsearch endpoints that are queried:

- Node: either /_nodes/stats or /_nodes/_local/stats depending on 'local'
  configuration setting
- Cluster Heath: /_cluster/health?level=indices
- Cluster Stats: /_cluster/stats
- Indices Stats: /_all/_stats
- Shard Stats: /_all/_stats?level=shards

Note that specific statistics information can change between Elasticsearch
versions. In general, this plugin attempts to stay as version-generic as
possible by tagging high-level categories only and using a generic json parser
to make unique field names of whatever statistics names are provided at the
mid-low level.

## Configuration

```toml @sample.conf
# Read stats from one or more Elasticsearch servers or clusters
[[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 obtain cluster health stats
  cluster_health = false

  ## 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 = false

  ## Only gather cluster_stats from the master node.
  ## To work this require local = true
  cluster_stats_only_from_master = true

  ## Indices to collect; can be one or more indices names or _all
  ## Use of wildcards is allowed. Use a wildcard at the end to retrieve index
  ## names that end with a changing value, like a date.
  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 have gathered.
  ## Valid options are "indices", "os", "process", "jvm", "thread_pool",
  ## "fs", "transport", "http", "breaker". Per 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

  ## Sets the number of most recent indices to return for indices that are
  ## configured with a date-stamped suffix. Each 'indices_include' entry
  ## ending with a wildcard (*) or glob matching pattern will group together
  ## all indices that match it, and  sort them by the date or number after
  ## the wildcard. Metrics then are gathered for only the
  ## 'num_most_recent_indices' amount of most  recent indices.
  # num_most_recent_indices = 0
```
