# NGINX Prometheus Exporter with systemd-activated socket
|
|
|
|
This example shows how to run NGINX Prometheus Exporter with systemd-activated socket.
|
|
|
|
## Prerequisites
|
|
|
|
- Linux machine with [systemd](https://www.freedesktop.org/wiki/Software/systemd/).
|
|
- NGINX Prometheus Exporter binary in `/usr/local/bin/nginx-prometheus-exporter` or a location of your choice. See the
|
|
[main README](../../README.md) for installation instructions.
|
|
- NGINX or NGINX Plus running on the same machine.
|
|
|
|
## Customization
|
|
|
|
Modify `nginx_exporter.service` and `nginx_exporter.socket` to match your environment.
|
|
|
|
The default configuration assumes that NGINX Prometheus Exporter binary is located in
|
|
`/usr/local/bin/nginx-prometheus-exporter`.
|
|
|
|
The `ExecStart` directive has the flag `--web.systemd-socket` which tells the exporter to listen on the socket specified
|
|
in the `nginx_exporter.socket` file.
|
|
|
|
The `ListenStream` directive in `nginx_exporter.socket` specifies the socket to listen on. The default configuration
|
|
uses `9113` port, but the address can be written in various formats, for example `/run/nginx_exporter.sock`. To see the
|
|
full list of supported formats, run `man systemd.socket`.
|
|
|
|
## Installation
|
|
|
|
1. Copy `nginx_exporter.service` and `nginx_exporter.socket` to `/etc/systemd/system/`
|
|
2. Run `systemctl daemon-reload`
|
|
3. Run `systemctl start nginx_exporter`
|
|
4. Run `systemctl status nginx_exporter` to check the status of the service
|
|
|
|
## Verification
|
|
|
|
1. Run `curl http://localhost:9113/metrics` to see the metrics exposed by the exporter.
