# Elasticsearch plugin

#### Plugin arguments:
- **servers** []string: list of one or more Elasticsearch servers
- **local** boolean: If false, it will read the indices stats from all nodes
- **cluster_health** boolean: If true, it will also obtain cluster level stats

#### Description

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](https://www.elastic.co/guide/en/elasticsearch/reference/current/cluster-health.html) stats.

Example:

```
    [elasticsearch]

    servers = ["http://localhost:9200"]

    local = true

    cluster_health = true
```

# Measurements
#### cluster measurements (utilizes fields instead of single values):

contains `status`, `timed_out`, `number_of_nodes`, `number_of_data_nodes`,
`active_primary_shards`, `active_shards`, `relocating_shards`,
`initializing_shards`, `unassigned_shards` fields
- elasticsearch_cluster_health

contains `status`, `number_of_shards`, `number_of_replicas`,
`active_primary_shards`, `active_shards`, `relocating_shards`,
`initializing_shards`, `unassigned_shards` fields
