Very useful for practitioners, check out OpenTelemetry Filelog Receiver: A Guide to Ingesting Log Files by the good folks from Dash0.

If you missed Embrace's Pumpkin spice and OpenTelemetry for mobile panel, now you can read up on the findings in all details. Thanks for sharing!
OTel updates¶
Two exciting things I stumbled upon in OpenTelemetry land:
- OTel Map is a really cool visualization tool that generates a topology based on OTel spans. Also available as open source, for DIY setups.
- Another example of this awesome community in action: have a look at the first alpha release of OpenTelemetry for Zig. Massive congrats!
