Since the @Prometheus 3.0 beta with the new UI got released at #PromCon yesterday, I wrote a blog post going into my motivations for creating the new UI and showcasing some of the cool new features in it:

https://promlabs.com/blog/2024/09/11/a-look-at-the-new-prometheus-3-0-ui/

PromLabs | Blog - A Look at the New Prometheus 3.0 UI

PromLabs - We teach Prometheus-based monitoring and observability

The goal of this new UI is not to be radically different with a ton of new features, but:

* Rewrite with a more modern stack (+Mantine)
* Make menus & pages cleaner, more consistent, and less cluttered
* Rethink a few minor things along the way
* More new features later

For anyone who wants to try out the new
@Prometheus UI (>90% done) that I'm currently building for Prometheus 3.0:

⬇️ git clone [email protected]:prometheus/prometheus
➑️ git checkout mantine-ui
πŸ” make build
▢️ ./prometheus --enable-feature=new-ui

Happy to hear feedback :)

I created a short follow-up video to my last video about @Prometheus histograms, this time explaining how to show histograms as a heatmap panel in Grafana:

Version 2.54 of @Prometheus comes with a nice new PromQL usability feature that allows you to use duration and number literals interchangeably, so you can write queries like this:

πŸ” time() - my_timestamp_seconds > 30d

I wrote a blog post explaining this new feature:

Wrote a blog post: Why you want to avoid large, multi-target exporters in
@Prometheus monitoring, and why many fine-grained scrape endpoints are much better! πŸš€
