exporter_proxy

Simple reverse proxy for prometheus exporters.

It is useful when it is difficult to open multiple ports on one server.

Install

Precompied binaries

Download from https://github.com/rrreeeyyy/exporter_proxy/releases

Docker

docker pull rrreeeyyy/exporter_proxy

go get

go get -u github.com/rrreeeyyy/exporter_proxy

Usage

$ exporter_proxy -config config.yml

If you make the following settings,

listen: "0.0.0.0:9099"

exporters:
  node_exporter:
    path: "/node_exporter/metrics"
    url: "http://localhost:9100/metrics"
  mysqld_exporter:
    path: "/mysqld_exporter/metrics"
    url: "http://localhost:9104/metrics"

When you access http://exporter_proxy_host:9099/node_exporter/metrics, returns the metrics collected by node_exporter.

And of course, http://exporter_proxy_host:9099/mysqld_exporter/metrics returns the metrics collected by mysqld_exporter.

The part of your prometheus.yml is probably as follows.

scrape_configs:
  - job_name: "node"
    metrics_path: /node_exporter/metrics
    static_configs:
      - targets: ["exporter_proxy_host:9099"]
  - job_name: "mysqld"
    metrics_path: /mysqld_exporter/metrics
    static_configs:
      - targets: ["exporter_proxy_host:9099"]
