If you have ever studied mathematics at a post-soviet university, you're probably familiar with the Demidovich textbook containing various mathematical problems.

The interesting thing about that book is that it has an antipode: the Anti-Demidovich. It explains all the solutions, but with one little nuance: it's all in Chinese.

This VictoriaMetrics book gives me the same vibe: https://github.com/ahfuzhang/InsideVictoriaMetrics

The Observability Data Connector helps you export Puppet data for your existing observability tools like Prometheus and Grafana. This walkthrough video, featuring Margaret Lee and Tony Green from the Puppet team, will show you how to setup the module and start displaying dashboards of your Puppet-managed infrastructure directly in Grafana so you can monitor trends over time and look for anomalies.

New 🌩️ Thunder: Service Mesh and Observability ♫
When I ask observability folks about service mesh, they shrug.
When I ask mesh folks about observability, they light up.
So… where’s the disconnect? (・・？)

@boredabdel and I talk through what a mesh shows you, what it misses, and what that means for your setup.
