Dash0 acquires Polar Signals

Dash0 updates from October 2025

8 updates shipped to Dash0 in October 2025: Dashboard variable bindings for all query types, Ability to hide explorer charts, Sorting for dashboard chart types and more.

Dashboard variable bindings for all query types

Tired of having to switch to PromQL mode just to be able to use dashboard variables? Today, we change that.

You can now bind any dashboard variable to any kind of filter in your queries, supercharging your custom dashboards and bringing a new level of dynamic control to all your observability views.

This update removes the previous limitation of variable usage only within specific query languages. We've introduced a flexible binding mechanism that allows you to map any existing dashboard variable to filters across all supported data sources. Be it logs, metrics, or traces.

Ability to hide explorer charts

Added the ability to hide charts in explorers, web monitoring sessions and resources, for increased usability of the tables, triage and grouping capabilities.

We've introduced the ability to hide the main (top-most) chart in various explorers. Hiding these charts gives you more screen real estate to display more entries (e.g., more logs in the logs explorer).

Sorting for dashboard chart types

Dashboard charts now support saving sorting configuration across multiple chart types. Sorting controls have also been unified into one location in the sidebar, along with the ability to simply click and sort on the charts themselves.

​​What’s New

We’ve added the ability to sort list and table legends for various chart types in dashboards.Additionally, we’ve also added the ability to sort the grids of both gauge and stats charts, along with the ability to also sort the slices of the pie chart.

Sorting is available for the following chart types:

  • Time series chart

  • Stat charts

  • Gauge charts

  • Time series table

  • Pie chart

  • Logs table

  • Geographical map

In addition to the above, we’ve also taken the chance of streamlining where the sorting controls live: they now appear consistently in the right sidebar of the Panel Edit screen.

It is also possible to directly sort a table by directly clicking on the column header whilst editing the panel

Auto-Instrumentation for .NET workloads

That latest releases of the Dash0 operator for Kubernetes adds zero-touch auto-instrumentation for .NET workloads.

Having to set up OpenTelemetry SDKs in your applications is a hassle. Wouldn't it be so much nicer if telemetry collection just worked automatically for your production workloads? Enter the Dash0 operator: Not only does it take care of setting up and configuring the OpenTelemetry collector for you, it also makes sure your applications send telemetry to the collector (and thus to Dash0), so you have end-to-end visibility into what is going on in your Kubernetes clusters.

The operator already supports automatic instrumentation for a few other runtimes, and now .NET joins the party. Starting with release 0.83.0 of the Dash0 operator, it will instrument .NET workloads for sending traces, metrics and logs automatically to Dash0.

Exponential Histograms

Dash0 now supports OpenTelemetry Exponential Histograms for a more accurate, high-resolution metric visualization.

We are excited to announce that Dash0 now supports Exponential Histograms — the next-generation histogram format introduced by OpenTelemetry.

Dash0 has already been ingesting and storing exponential histograms from OpenTelemetry sources, but until now these metrics could only be listed in the UI. With this update, exponential histograms can be queried and visualized, allowing you to explore, graph, and analyze these metrics alongside regular histograms.

Unlike regular histograms with fixed bucket boundaries, exponential histograms use dynamically scaled buckets that automatically adjust to the magnitude of recorded values. This allows Dash0 to:

  • Efficiently represent metrics with** high dynamic ranges** (for example, latency from microseconds to seconds).

  • Maintain higher precision without excessive memory usage.

  • Provide smoother and more accurate visualization for metrics such as latency, request duration, or payload sizes.

Dash0 ingests and stores OpenTelemetry exponential histograms in their native form, translating them into native histogram representation for querying and visualization in the UI. This ensures full compatibility with OpenTelemetry data while preserving the precision and scale of the original metrics.

This update allows you to **use any of the standard **Prometheus histogram functions — such as histogram_quantile() — with full precision and scale preserved from the original OpenTelemetry data.

Access Control - Share Check Rules and Synthetics Checks

With this release, Access Control in Dash0 is now complete: all observability assets - including dashboards, views, check rules, and synthetic checks can be shared with Teams and individual users.

What’s New

✅ Synthetic Check Sharing: Synthetic Checks can now be shared just like dashboards, views, and check rules - with edit permissions.

✅ Check Rule Sharing: Check Rules, previously unsharable, can now be granted to Teams or individual users with edit permissions.

👥 Consistent Collaboration: Every observability asset now follows the same model. Share once with a Team, and everyone gets the right access level.

🔎 Visibility Built-In: See exactly which assets are shared with which Teams and users, directly from Team and User settings.

Why It Matters

This release closes the loop on Access Control in Dash0. You can now manage sharing across all key observability assets with the same, simple model - giving teams the flexibility to collaborate while keeping management clear and oversight consistent.

Introducing log tables in dashboards

Bring your logs directly into your dashboards for unified observability

Many Dash0 users have asked for the ability to show lists of logs in Dashboards. And now you can:

The Log Table widget allows you to visualize, filter and analyze your logs along all the other data in a Dashboard.

TV Mode for dashboard panels

TV Mode now supports opening and viewing dashboard panels, enabling teams to inspect detailed metrics and queries while maintaining the distraction-free full-screen experience.

What’s New

Panels can now be opened and viewed directly in TV mode (sometimes referred to "kiosk" mode) similarly to what is possible already with entire dashboards.

Also, we took the chance to make it clearer when you're in TV Mode, and how you can get out of it.
