Over the past six weeks, we introduced a series of impactful updates aimed at making your observability workflows faster, more unified, and more collaborative. Here’s a snapshot of what we worked on.

Frontend development has evolved rapidly over the past decade, but one challenge remains constant: understanding what’s happening in real-time across diverse browsers, environments, and user interactions. This is where observability steps in—but how does it apply to the frontend world where user experience can break in countless, unexpected ways?

Real user monitoring (RUM) began as a straightforward approach to tracking basic web performance metrics. Focused on things like page load times and response rates, RUM relied on server-side logging and simple browser timings. While these tools captured Core Web Vitals (CWVs), they offered limited insights into how users actually interacted with pages, focused mainly on server-side performance.

Hint: Append them to your structured logs or spans.

Recently, we announced the launch of Honeycomb for Frontend Observability, our new solution that helps frontend developers move from traditional monitoring to observability. What this means in practice is that frontend developers are no longer limited to a metrics view of their app that can only be disaggregated in a few dimensions. Now, they can enjoy the full power of observability, where their app collects a broad set of data as traces to enable much richer analysis of the state of a web service.

Refinery is Honeycomb’s sampling proxy, which our largest customers use to improve the value they get from their telemetry. It has a variety of interesting samplers to choose from. One category of these is called dynamic sampling. It’s basically a technique for adjusting sample rates to account for the volume of incoming data—but doing so in a way that rare events get more priority than common events. Honeycomb’s query engine can compensate for sampling rates on a per-event basis.

We’ve posted before about how engineers on call at Honeycomb aren’t expected to do project work, and that whenever they’re not dealing with interruptions, they’re free to work on whatever will make the on-call experience better. However, all of our engineering rotations rely on hand-off meetings where they update the Slack groups with everyone who’s on call. During my last shift, a small problem kept causing friction for some of our incident management automation.

As our software complexity increases, so does our telemetry—and as our telemetry increases, it needs more and more tweaking en route to its final destination. You’ve likely needed to change an attribute, parse a log body, or touch up a metric before it landed in your backend of choice. At Honeycomb, we think the OpenTelemetry Collector is the perfect tool to handle data transformation in flight. The Collector can receive data, process it, and then export it wherever it needs to go.
