The tracing UI is amazing. When we switched to Dash0, it significantly cut down the amount of time from a bug being reported to figuring out why it happened and fixing it. Filtering on attributes is extremely intuitive, and the tracing tree UI is awesome.

Catch slow queries and memory leaks before they burn through your Puma workers

Process memory, GC stats, thread counts, and Sidekiq queue depth for Ruby in production.

Runtime Metrics

Find the runtime bottleneck behind "Ruby is slow"

Track process RSS, GC.stat heap slots and object allocations, active thread count, and CPU time. Spot memory leaks and heap growth in long-running Puma workers before they force a restart.

Concurrency Context

See the full picture across Sidekiq jobs, Puma threads, and HTTP calls

Distributed traces that follow context through Puma's threaded request handling, Sidekiq job queues, and Rails middleware. You see the full flow from web request to background job, not just the Rack request.

Connect the signal to the incident

Logs, traces, metrics, and alerts in one connected view. Click from one to any other.

Trace any log line back to its originating request
Signal Correlation

Trace any log line back to its originating request

Navigate directly from a log line to the trace that generated it, then drill from any span into the associated metrics. Supports Ruby’s standard Logger and Rails tagged logging out of the box. OpenTelemetry trace-context correlation and Dash0’s resource-centric architecture handle the linking automatically—no manual instrumentation or custom correlation logic required

Alerting

Detect issues before they impact users

Define alerts for Ruby process memory, Sidekiq queue depth, and Rails request latency using PromQL or the visual query builder. Reuse community-maintained rules from Awesome Prometheus Alerts, then route notifications to email, Slack, or any webhook endpoint.

Start seeing telemetry in minutes, not days

dd the OpenTelemetry gems to your Gemfile, configure the SDK at boot, and your app starts exporting traces. No code changes required.

Setup

bundle add, configure an initializer, done

Add opentelemetry-sdk, opentelemetry-exporter-otlp, and opentelemetry-instrumentation-all to your Gemfile, then configure OpenTelemetry::SDK.configure in a Rails initializer or boot file. Works with Puma, Unicorn, or Passenger.

Kubernetes

Zero-code instrumentation via the Dash0 Operator

The Dash0 Operator auto-instruments Ruby pods on Kubernetes with zero code changes — Rails apps, Bundler-managed services, and plain Ruby scripts on Ruby 3.3 or later.

Agent Skills

Teach your coding agent OpenTelemetry

Open-source skills for Claude Code, Cursor, Windsurf, and 38+ other AI coding agents. Correct resource attributes, span status codes, and Collector patterns from the first commit.

Keep your observability stack portable

Use standard OpenTelemetry across instrumentation, export, and querying without proprietary agents or vendor-specific code in your repository.

OpenTelemetry

Build on OpenTelemetry, not vendor lock-in

Dash0 is OpenTelemetry-native by design. Instrument with the official OpenTelemetry Ruby SDK while preserving semantic conventions and resource attributes end to end, so telemetry remains standardized and portable across distributed systems.
