Elasticsearch Exporter Build Status

Docker Pulls Go Report Card

Prometheus exporter for various metrics about ElasticSearch, written in Go.


For pre-built binaries please take a look at the releases.

docker pull justwatch/elasticsearch_exporter:1.0.2
docker run --rm -p 9108:9108 justwatch/elasticsearch_exporter:1.0.2

Example docker-compose.yml:

    image: justwatch/elasticsearch_exporter:1.0.2
     - '-es.uri=http://elasticsearch:9200'
    restart: always
    - ""

NOTE: The exporter fetches information from Elasticsearch cluster on every scrape, therefore having too tight scrape interval can impose load on ES master nodes, particularly if you run with -es.all and -es.indices. We suggest you to measure how long does it take to fetch /_nodes/stats and /_all/_stats for your ES cluster and consider whether your scrapping interval is too tight. As a last resort, you can scrape this exporter through a dedicated job with its own scraping interval.

Below is the command line options summary:

elasticsearch_exporter --help
Argument Description
es.uri Address (host and port) of the Elasticsearch node we should connect to. This could be a local node (localhost:9200, for instance), or the address of a remote Elasticsearch server. When basic auth is needed, specify as: <proto>://<user>:<password>@<host>:<port>. E.G., http://admin:pass@localhost:9200.
es.all If true, query stats for all nodes in the cluster, rather than just the node we connect to.
es.indices If true, query stats for all indices in the cluster.
es.timeout Timeout for trying to get stats from Elasticsearch. (ex: 20s)
es.ca Path to PEM file that contains trusted CAs for the Elasticsearch connection.
es.client-private-key Path to PEM file that contains the private key for client auth when connecting to Elasticsearch.
es.client-cert Path to PEM file that contains the corresponding cert for the private key to connect to Elasticsearch.
web.listen-address Address to listen on for web interface and telemetry.
web.telemetry-path Path under which to expose metrics.
version Show version info on stdout and exit.

Alerts & Recording Rules

We provide examples for Prometheus alerts and recording rules as well as an Grafana Dashboard and a Kubernetes Deployment.

The example dashboard needs the node_exporter installed. In order to select the nodes that belong to the elastsearch cluster, we rely on a label cluster. Depending on your setup, it can derived from the plattform metadata:

For example on GCE

- source_labels: [__meta_gce_metadata_Cluster]
  separator: ;
  regex: (.*)
  target_label: cluster
  replacement: ${1}
  action: replace

Please refer to the Prometheus SD documentation to see which metadata labels can be used to create the cluster label.
