elasticsearch-exporter部署手册

来源

https://github.com/prometheus-community/elasticsearch_exporter

说明

用于 ElasticSearch 的各种指标的 Prometheus 导出器，由 Go 语言编写。
导出器在每次抓取时从 ElasticSearch 集群中获取信息，因此抓取间隔太短会给 ES 主节点带来负载，尤其是当您使用 --es.all 和 --es.indices 运行时。 我们建议您测量 ES 集群获取 /_nodes/stats 和 /_all/_stats 所需的时间，以确定您的抓取间隔是否太短。 作为最后的手段，您可以使用具有自己的抓取间隔的专用作业抓取此导出器。

部署方式:

docker部署

docker pull quay.io/prometheuscommunity/elasticsearch-exporter:latest
docker run --rm -p 9114:9114 quay.io/prometheuscommunity/elasticsearch-exporter:latest

    command:
     - '--es.uri=http://elasticsearch:9200'
    restart: always
    ports:
    - "127.0.0.1:9114:9114"
