Elasticsearch Search Exporter

This is an exporter that allows you to execute queries against an Elasticsearch cluster and return the number of documents found for use by the Prometheus monitoring system.

Installation

pip install es_search_exporter

ES Search Exporter Configuration

You will need to add your Elasticsearch query to the searches hash in es_search.yml. This could also be a JSON file as well if that would make it easier (JSON is valid YAML, and most tools like Kibana can produce a JSON version of your query).
