# Elasticsearch input plugin
The [elasticsearch](https://www.elastic.co/) plugin queries endpoints to obtain
[node](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-nodes-stats.html)
and optionally [cluster-health](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-health.html)
or [cluster-stats](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-stats.html) metrics.
### Configuration:
```
[[inputs.elasticsearch]]
## specify a list of one or more Elasticsearch servers
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 = false
## Adjust cluster_health_level when you want to also obtain detailed health stats
## The options are
## - indices (default)
## - cluster
# cluster_health_level = "indices"
## Set cluster_stats to true when you want to also 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
## 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"]
## 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
```
### Status mappings
When reporting health (green/yellow/red), additional field `status_code`
is reported. Field contains mapping from status:string to status_code:int
with following rules:
* `green` - 1
* `yellow` - 2
* `red` - 3
* `unknown` - 0
