Dash0 acquires Polar Signals
Monitor Vercel log drain events and link them to tracing data for comprehensive system visibility and troubleshooting.
Vercel's powerful front-end cloud accelerates and improves UI development. Projects hosted on Vercel natively generate logs and can generate tracing data through Vercel's @vercel/otel NPM package. You can fully leverage this data through Dash0.
Insights into Vercel project's HTTP requests and logging activity.
Vercel deployment is experiencing errors
Alert triggers when Vercel deployments show elevated 5xx error rates above 5%.

Alert triggers when request rate changes significantly compared to previous hour.
Vercel preview deployment health issues
Alert triggers when preview deployments show elevated error rates above 10%.
Vercel's frontend cloud supports two types of telemetry: logs and traces. This guide will describe how to set up both, starting with logs, which is very easy thanks to Dash0's native Vercel integration.
In short, click the button below and follow the dialog.
Vercel has its own distribution of the OpenTelemetry SDK called @vercel/sdk. It is fully compatible with the official
OpenTelemetry SDK, and adds helpful extensions.
If you are using a Next.js version <15, you need to enable the Next.js instrumentation hook. Modify the file next.config.js with the following settings:
Now you can initialize Vercel's OpenTelemetry SDK via a file called instrumentation.ts (see documentation, located directly in your src/ folder). Add the following content:
As the last step, we need to tell the Next.js OpenTelemetry SDK where to send its data to, and how to authenticate. This can be achieved using the standardized OpenTelemetry headers and Vercel's environment variable support.
Distributed tracing data will now arrive from Vercel within Dash0!
