Express Monitoring & Error Tracking
See every error, slow request, and failing dependency in your Express API — in real time, on one platform.
Production-grade Express monitoring without the sprawl
Express runs lean, which means failures surface as raw stack traces in your logs or as a 500 your user already saw. Express monitoring closes that gap: it captures unhandled errors with full context, times every route and database call, and tells you which deploy introduced a regression — so you fix issues before they spread instead of grepping logs after the fact.
AllStak ships a first-class Express SDK that plugs into the request lifecycle: add the request handler before your routes and the error handler after them, and error tracking, request monitoring, and distributed tracing start automatically. Everything lands in one platform alongside your logs, infrastructure, uptime, and alerts — one bill, SAR pricing, and a free tier to start.
Everything you need to monitor Express
From the first uncaught exception to the slow query behind a timeout, AllStak gives Express teams the full picture in one place.
Real-time error tracking
The Express error handler captures unhandled exceptions automatically, with stack trace, request context, and release — grouped so duplicates collapse into one issue.
Performance & tracing
Distributed tracing follows a request across services with W3C traceparent headers, so you can see exactly where a slow Express endpoint spends its time.
Requests & queries
The request handler records every inbound route with status, latency, and method, and traces outbound HTTP and database calls — find the query behind the slow response.
Releases & regressions
Tag each deploy with a release so new errors are attributed to the exact version that shipped them — spot a regression the moment it goes live.
Infrastructure monitoring
A lightweight host agent reports CPU, memory, disk, network, processes, and Docker for the servers your Express app runs on — correlate spikes with errors.
Smart alerts & incidents
Alert on new errors, error-rate spikes, or latency thresholds, then route incidents to your team — so you hear about a problem before your users do.

What you see in AllStak
Error detail with full context
Open an issue to see the exception, full stack trace, the request that triggered it, environment and release, and how often it has occurred — everything needed to reproduce and fix.
Traces & slow requests
Follow a single request as a waterfall of spans across routes, outbound calls, and database queries, so the slowest segment of an Express endpoint is obvious at a glance.
One real-time dashboard
Errors, request throughput, traces, logs, infrastructure health, and uptime live on one real-time dashboard — no tab-switching between separate monitoring tools.

Express monitoring FAQ
How do I add monitoring to my Express app?
Install the AllStak SDK, add the request handler before your routes and the error handler after them, and set your project API key. Error tracking, request monitoring, and tracing start automatically — the setup guide in our docs has the exact snippet.
Is Express monitoring free?
Yes — AllStak has a free tier you can start on with no card required. Paid plans use predictable SAR pricing as your traffic grows, with one bill across every capability.
Does it capture errors and performance, or just errors?
Both. The error handler captures unhandled exceptions, while the request handler records inbound routes and distributed tracing follows requests across services and database calls — so you get error tracking and performance monitoring together.
Will it slow down my Express server?
No. The SDK runs as lightweight middleware and sends telemetry asynchronously, so it stays out of your request hot path. You control sampling rates and whether request and response bodies are captured.
Does it work with TypeScript and existing middleware?
Yes. The SDK ships type definitions and works alongside your existing Express middleware — register the request handler early and the error handler last, after your routes and other error handlers.
Can I monitor my whole stack, not just Express?
Yes. AllStak is an all-in-one platform: alongside Express it monitors logs, infrastructure, websites and uptime, SSL certificates, security and CVE scanning, and more — with drop-in SDKs for many other languages and frameworks.
