If you think logging is boring, stop yawning and think again!

Designed for the ages of monolithic synchronous applications running in data centers or on the desktop, traditional text-file-oriented logging frameworks such as log4net or nlog are becoming obsolete. New tools, best-practices and standards are emerging to make sense out of massively distributed and asynchronous applications that run in the cloud, in containers, or in mobile devices. Solutions for a world where storage and computing power are cheap and can be provisioned within minutes.
Starting with the question “what do we want to log and why?”, this talk gives a bird’s eye overview of the new logging landscape. It introduces open-source solutions like Elasticsearch, Fluentd or OpenTracing, and commercial services like Application Insights. On a code level, it shows how PostSharp can help to generate highly detailed logs with minimal efforts.
The key takeaway of this talk is a broad understanding of the business of logging and application instrumentation, so you’re ready to make choices on your own.
