Recent changes and improvements to Dash0

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.

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.

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.

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.

Dash0’s Website monitoring gives you complete visibility into your application's performance from frontend to backend. By correlating web vitals with backend API calls, you can easily identify customer issues and understand the full user journey.

OpenTelemetry provides well-defined interfaces for end-to-end tracing from client to the backend up until the database using context propagation headers. However, some key AWS services do not make use of this out of the box because of implementation details, specifically the format they use for trace context propagation (see our guide on distributed tracing for more details). Amazon API Gateway, Application Load Balancer and others don't use the W3C TraceContext specification, which OpenTelemetry uses by default: instead, the trace data they generate, which you can get into Dash0 using the Amazon CloudWatch Transaction Search integration, relies on you perform tracing via the AWS X-Ray headers. The outcome is that you may not get the full picture of your application's performance.

To prevent these issues, we've added X-Ray propagation support to our Web SDK, automatically bridging the gap between your frontend and AWS backend services. Now you can trace user interactions seamlessly through your entire AWS-powered application stack, giving you the complete observability you need to deliver exceptional user experiences.

Audit logs are essential for security, compliance, accountability, and cyber forensics. They help in detecting unauthorized activities and providing accountability for personnel. They track user actions, system changes, and events, which is crucial for identifying anomalous behavior, ensuring regulatory compliance, and providing actionable insights for investigations.

Key Benefits

• Enhanced Visibility: It provides a chronological record of activities. This helps in understanding the intent behind activities.
• Security and Compliance: Audit logs are essential for security, compliance, accountability, and cyber forensics. They help in detecting unauthorized activities and providing accountability for personnel. They track user actions, system changes, and events, which is crucial for identifying anomalous behavior, ensuring regulatory compliance and providing actionable insights for investigations.

You can find the new Audit Logs feature in your organization settings.

What’s New

• 👥 Team Management: Maintaining Teams within your organization.
• ➕ User Management: Add or remove users from Teams.
• 📊 Asset Sharing: Share Dashboards and Views with entire Teams, roles or individual users.
• 🔎 Visibility Controls: Check which assets are shared with Teams and Users directly in the sharing sidebar.

🔑 Simplified Collaboration: Manage access once per Team instead of assigning permissions user by user.

This is the first step in bringing granular Access Control to Dash0, with more granular permissions coming soon.

In terms of feature support, it is 100% equivalent to the AWS-based regions.

By the way, you can also onboard to this GCP region directly from the GCP Marketplace.

What’s New

• 🇬🇧 London (UK) – monitor performance closer to your users in the United Kingdom.
• 🇩🇪 Frankfurt (DE) – gain insight into response times within central Europe.
• 🇺🇸 North Virginia (US) – measure latency from one of the key internet hubs in the United States.

Why This Matters

Synthetic monitoring from more regions helps you better understand your application’s performance where your users are. With these additions, you can pinpoint regional bottlenecks, improve reliability, and deliver faster digital experiences.

The latest version of the Dash0 Terraform Provider introduces the ability to manage check rules and views directly through Terraform, enabling you to deploy monitoring resources as code. You can now define alerting rules and custom views declaratively within your Terraform configurations. The provider automatically synchronizes these resources with your Dash0 organization, simplifying setup and maintenance of observability resources through infrastructure as code. This enhancement streamlines monitoring workflows and improves automation for users managing multiple environments.
