Event Payloads in the Trace
The input that caused the failure
The extension captures the full event that triggered the invocation, an SQS message, an EventBridge event, a Kinesis record, and attaches it to the trace.
Serverless Monitoring
Serverless Monitoring That Goes All the Way to Root Cause
A Lambda function is gone by the time you start investigating. Dash0 captures what triggered the invocation, what it was processing, and what killed it, before the function disappears.

What I love most about Dash0 is that it's fully OpenTelemetry native which has significantly improved our software development process. The seamless navigation from logs to traces to metrics streamlines bug diagnosis and troubleshooting, enhancing our team's efficiency.
Elliot Dauber
Software Engineer - Vercel
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.

Dash0's foundation on open source standards ensures future-proof and next-gen observability. Their focus on ease of use empowers all of our developers to gain insights quickly.
See exactly why a function failed
The Dash0 Lambda Extension runs as a sidecar alongside your function. Add the layer, set three environment variables, no other code changes. Sensitive fields are masked by default, with custom masking rules available per payload type.
Synthetic Traces for Timeouts and OOM
Failures that never produce a trace, captured anyway
When a function times out or runs out of memory, the runtime kills it before any trace can be emitted. The extension detect the failure and generate a synthetic trace: duration, trigger source, batch size, failure type.
One connected trace
Full Event Chains Across Brokers
Trace context propagates across SQS, SNS, EventBridge, and Kinesis. Each hop carries its event source and batch record count, so a fan-out across multiple brokers stays traceable end to end.
Full traces with Lambda context built in
Every invocation produces a complete trace, enriched with the details your application code never sees.
Lambda Context on Every Span
Full Invocation Metadata
The root span carries invocation ID, event source, and batch record count using standard OTel semantic conventions.
Cold Start Analysis
faas.init_duration on every cold invocation
Cold starts get their own metric on the invocation span. Track trends, compare across runtimes and memory configurations, correlate spikes with latency.
Log-Trace Correlation
One click from a log line to its trace
Logs are linked to their invocation trace via a shared invocation ID. Jump from a log line straight to the full trace.
Turn it on without touching your code
Add the extension from the Lambda functions catalog, or bring your own OpenTelemetry setup.
One-Click From the Catalog
Instrument straight from Dash0
Select functions in the AWS Lambda catalog and Dash0 adds the extension for you.
Already on OpenTelemetry?
Keep your setup and add the enrichment
Point your existing OTLP exporters at the extension’s local endpoint and keep your instrumentation as-is. You get Lambda context, payload capture, and synthetic traces on top, without changing your code.
Serverless Framework
One flag per function
The serverless-dash0 plugin configures the extension automatically for any function marked in your serverless.yml.
