Observability & Monitoring Community Slack

Come hang out with all your fellow Monitoring Weekly readers. I mean, I’m also there, but I’m sure everyone else is way cooler.

We hear about the sidecar pattern all the time, but rarely with an explanation of what it is or why we should care. Here you go.

Kubernetes HPA optimization based on any metric

How to autoscale your Kubernetes systems using any custom metric. Yes please and thank you.

Getting started with eBPF and Cilium on GKE

Although this article isn’t specifically about monitoring, it provides a broader explanation of eBPF and Cilium. I’m starting to see both of technologies used a lot among monitoring and observability teams.

Cilium TLS inspection

Speaking of Cilium, here’s one very specific use case for leveraging it to inspect TLS certs. This is an excellent technical walkthrough, with tons of accurate code examples and helpful diagrams.

What is KUTTL?

Good monitoring and testing goes hand in hand. Here’s an interesting tool I first learned about this week for testing Kubernetes operators.

Autonomous Monitoring and Self-Healing Networks

I don’t hear much these days about self-remediation (outside of Kubernetes), so this one piqued my interest. Good read about how Salesforce’s CDN integrates monitoring with autonomous interventions.

Who is the winner — Comparing Vector, Fluent Bit, Fluentd performance

A comparison of three popular log aggregators. I’d like to see more dimensions covered (e.g. transforms, metrics exporting, etc) but it’s still a useful look at how each performs at basic log collection duties.

5 open source APM tools compared

Ever wonder why we don’t hear more about open source APM tooling (i.e. is it even a thing?). Wonder no more, this article has you covered.

Securing Your OpenTelemetry Collector (updated)

According to this author, most of the existing documents out there for setting up an OpenTelemetry deployment either gloss over – or provide outdated details – for setting up encryption and authentication. This article aims to fill those gaps with current and relevant examples.

Production issues: the owl effect

Some questions raised and lessons learned about observability in a production environment.

Establish an on-call program

One CTO’s reflection on the importance of an on-call program. Probably obvious to most of us, but possibly helpful to share (or not) with your favorite CxO.



KUbernetes Test TooL (KUTTL) provides a declarative approach to test Kubernetes Operators.
