Elasticsearch Exporter

grafana-agent内置了elasticsearch_exporter，可以采集Elasticsearch的运行指标。

目前grafana-agent不支持配置多个elasticsearch的地址，只能配置一个ElasticSearch地址对其进行metrics的采集。

我们强烈推荐您使用独立的账号运行grafana-agent，并做好访问elasticsearch实例的最小化授权，避免过度授权带来的安全隐患，更多可以参考official documentation。

配置并启用elasticsearch_exporter

  1. elasticsearch_exporter:
  2.   enabled: true
  3.   address: "http://localhost:9200"
