An engineer at tb.lx talks about their adoption of observability practices and tooling, and how it’s leading to better outcomes for not just their internal teams and business outcomes, but for better understanding customer issues.

Ensuring the Successful Launch of Ads on Netflix

IMHO you can’t do proper monitoring without some manner of baseline performance testing before going to production. I love this post from Netflix on how they leveraged replay traffic to ensure the smooth rollout of a major new feature.

A fine-grained network traffic analysis with Millisampler

You can always count on Facebook to deliver some unique tooling around very challenging technical domains. Their 2022 paper on “microscopic traffic bursts” in the datacenter is a fascinating read. This has recently been followed up with a video and blog post detailing their Millisampler tool designed specifically for inspecting traffic dynamics at sub-second granularity.

A comparison of eBPF Observability vs Agents and Sidecars

I don’t believe that traditional instrumentation approaches are going anywhere, but eBPF is making a strong case for less intrusive metrics collection.

OpenTelemetry Dynamic Integrations

OpenTelemetry already has a strong reputation for portability but this example really underscores just how easy it is to switch your final destination(s) using OTel collectors.
