Prometheus nginx socket exporter

stand-alone version of k8s/ingress-nginx' prometheus exporter

based on openresty/lua-nginx-module

how it works

exporter opens socket (/tmp/prometheus-nginx.socket) and waits for Nginx workers to send logs every second

Nginx config should have monitor.lua and monitor.conf from this repo

user config may be instrumented with service_name and location_path that go as labels, see example default.conf

server {
    set $service_name  "app8080";
    listen       8080;
    location / {
        set $location_path  "/backend";
        proxy_pass http://backend;
    }

how to run

docker build . -t r
docker run -it -p8080:8080 -p10254:10254 r

nginx -- http://localhost:8080/debian/doc/

metrics -- http://localhost:10254/metrics

this exporter metric list

curl -s 127.0.0.1:10254/metrics |grep -v ^# | cut -d'{' -f1|cut -d' ' -f1 | sort | uniq
