This exporter intented to expose metrics based on Elasticsearch queries. This exporter never run in production, so use it on your own risk :-)
Any modern Linux distro (Arch, Ubuntu, CentOS, Debian).
Following python2.7 libraries are required: pyyaml, requests, prometheus_client
Configuration file is in a yaml format with single configuration scope (metrics).
Each item in metrics scope define a metric and must have following attributes:
- metric_desc - description of a metric (what it does)
- metric_value - reference to value in Elasticsearch response (json data)
- metric_labels - inner scope with `metric_name: reference` for each metric:
- metric_name - name of label exposed by exporter
- reference - reference to value in Elasticsearch response (json data)
- es_url - url to Elasticsearch cluster (include index)
- es_query - query in json format - MUST be inclosed in single quotes - e.g. '{ "query": {...} }'
