Hynek Schlawack - Beyond grep: Practical Logging and Metrics [EuroPython 2015] [21 July 2015] [Bilbao, Euskadi, Spain] Knowing that your application is up and running is great. However in order to make informed decisions about the future, you also need to know in what state your application currently is and how its state is developing over time. This talk combines two topics that are usually discussed separately. However I do believe that they have a lot of overlap and ultimately a similar goal: giving you vital insights about your system in production. We'll have a look at their commonalities, differences, popular tools, and how to apply everything in your own systems while avoiding some common pitfalls. **Slides & Notes**: [https://hynek.me/talks/beyond- grep/](https://hynek.me/talks/beyond-grep/)
