If there’s one thing developers can’t get enough of, it’s tools. Azure, the cloud computing platform from Microsoft, offers over 100 services and tools for building infrastructure and running software apps. Each of these services produces log files in various formats, containing a slew of important details such as service health and status, performance metrics, and resource access requests—everything developers need to monitor Azure and keep their apps running smoothly.
Life would be much simpler if applications running inside containers always behaved correctly. Unfortunately, as every sysadmin and developer knows, that is never the case. When things inevitably start going wrong you need diagnostic information to figure out how and why. Being able to gather useful information from your Docker container logs can mean the difference between a minor issue and a critical outage.
