Calling All Docker Fanatics: How Are You Using Docker Stats (via Sumo Logic)?

    At our company Fugro Roames, we use Docker and Sumo Logic as a part of our deployment automation. We use Ansible scripts to automatically deploy our developer's applications onto Amazon EC2 instances inside Docker containers as part of our cloud infrastructure. These applications are automatically configured to send tagged logs to Sumo Logic using Fluentd, which our developers use to identify their running instances for debugging and troubleshooting. Not only are the application logs sent directly to Sumo Logic, but the Docker container logs are also configured using Docker's built in Fluentd logging driver. This forwards logs to another Docker container on the same host running a Fluentd server, which then seamlessly ships logs over to Sumo Logic. The result is developers easily access their application and container OS logs that their app is running in just by opening a browser tab. Roames uses remote sensing laser (LIDAR) technology to create interactive 3D asset models for powerline networks for energy companies in our home country of Australia, and also internationally in the United Kingdom. Part of our development has also been trialling drones for asset inspection, and we also have a few drone fanatics in our office. Winning a drone would also be beneficial as it would give us something to shoot at with our Nerf guns, improving office morale.

    @Brandon Milsom Great post and visual - thanks for sharing! Seems like there's already quite a drone culture there :) Inasmuch as you can share, do you have an example of something interesting / unique that you've found in in either your application logs or container logs, which you've been able to troubleshoot and take action on? I'm sure there are lots of examples every day -- but is there anything that stands out that you can share publicly (please anonymize / obfuscate specifics)?

    Hi @Maria Ogneva, I think one of the best things that we've gained from this setup is that it allows us to keep users from connecting (SSH) in to our instances. Given our CD setup, we don't want users connecting in to hosts where their applications are deployed (it's bad practice). However, we had no answer to the question of how they get their application/OS logs. Thanks to SumoLogic (and the Docker logging driver!), we're able to get these logs out to a centralized location, and keep the users out of the instances. We're fairly new to the world of SumoLogic, so we haven't even begun looking at event correlation, anomaly detection, etc. But we're looking forward to seeing what we can learn from all the information we are gathering. Cheers, Adrian Fugro Roames

    Well, we didn't get a lot of feedback on this, but one well-told story is all it takes. I'd like to congratulate @Brandon Milsom for sharing how Fugro Roames uses the FluentD log driver to send tagged logs to Sumo Logic. As his colleague @Adrian Howchin points out, Sumo Logic allows their developers to access Docker logs without having to SSH into host instances. I doubt nurf bullets will do much to dissuade the flight path. I hope everyone in the office has fun shooting Please send photos. @Maria Ogneva will be in touch to make arrangements to deliver your new DJI Phantom 3 Drone! Kind Regards, -- Michael

    Huge congrats @Brandon Milsom !!! I will be in touch via email to get your address to ship the drone to your office. I hope you let @Adrian Howchin play with it too :) We must get photos of you with the drone when you get it!

    Thank you all for putting this together! Don't worry, we'll send you all plenty of photos, both of the drone, and from it! @Adrian Howchin can have a go too :D
