Statist

The simple way to share MTProto proxy stats from the original container.

Problem

You can not expose the port with stats outside from official docker-container.

The MTProto proxy server exports internal statistics as tab-separated values over the http://localhost:2398/stats endpoint. Please note that this endpoint is available only from localhost: depending on your configuration, you may need to collect the statistics with docker exec MTProto proxy curl http://localhost:2398/stats.

This project solves this problem.

Solution

Run separate container that can run docker exec ... command on MTProto proxy container. It's not the best solution, but it's the easiest way, if You do not want to rebuild original MTProto proxy container.

Usage

The simple docker-compose file must look like this:

version: '3'

services:
  proxy:
    image: telegrammessenger/proxy:latest
    container_name: "${CONTAINER_NAME}"
    ports:
      - "443:443"
    volumes:
      - "proxy-config:/data"
    restart: unless-stopped
    environment:
    - TAG="${TAG}"
    - SECRET="${SECRET}"
  statist:
    image: kanaglic/statist:latest
    container_name: statist
    restart: unless-stopped
    ports:
      - "8080:8080" #if You want to share stats on this port
    command: "${CONTAINER_NAME}" #important to set correct container name of  MTProto proxy container.
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock #important to share origin docker socks
volumes:
  proxy-config:

Now you can see some stats on some port like this: curl localhost:8080. Just for now output format is influxDB line format, but it's easy to make another formats - feel free to add issue or PR.

Why influxDB

I use this output with telegraf and influxDB, so, just because.

Develop

1. git clone
2. dep ensure
3. env GOOS=linux GOARCH=amd64 go build .
4. docker build -t YOUR_REGISTRY/statist .
5. docker push YOUR_REGISTRY/statist

or use Makefile make REGISTRY=YOUR_REGISTRY

Docker image

Yes, of course, You can use the image from docker hub docker pull kanaglic/statist
