I installed docker-logion according instructions from README:

docker run -d --name logio -p 28777:28777 -p 28778:28778 temal/logio-server
docker run -d --privileged --link logio:logio -v /var/run/docker.sock:/var/run/docker.sock gerchardon/docker-logio -n `uname -n` -h logio

Now at http://localhost:28778 I see streams from all docker containers, but no messages (I knew that new messages are generating, because I see new messages in docker logs some-container).

Environment: Ubuntu 14.04 with Docker 1.8.2, all images pulled just now.

# docker logs logio

How can I debug why it's not working?

gerchardon commented

It's a warning for memory leak but it's work see https://nodejs.org/api/events.html#events_emitter_setmaxlisteners_n

Docker 1.8 need newer dependencies to see log (I will commit package.json with update dependencies)

If you want to debug it or run in standalone mode :

git clone https://github.com/gerchardon/docker-logio.git
cd docker-logio
npm install
node index.js

New Version with fix v0.3.0 (npm ready , docker hub soon)

rutsky commented

I tested 0.3.0 --- it works, thanks for such quick response, @gerchardon!

rutsky commented

By the way: it doesn't work on Docker version 1.7.1.
Fails with:

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: connect ECONNREFUSED
    at errnoException (net.js:905:11)
    at Object.afterConnect [as oncomplete] (net.js:896:19)

Not sure if you should support older Docker versions.

I had error in my configuration, looks like it should work, sorry for the noise.
