Simple reverse proxy for prometheus exporters.
It is useful when it is difficult to open multiple ports on one server.
Download from https://github.com/rrreeeyyy/exporter_proxy/releases
docker pull rrreeeyyy/exporter_proxy
go get -u github.com/rrreeeyyy/exporter_proxy
$ 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"]
