Not sure why that API’s slow? Or where that crash came from? With connected context—from the first user action through every service, system, and line of code—Sentry gets you to the fix fast, without digging through five different tools.
Debug with Tracing
More questions answered
How can I catch slowdowns before users do?
Set metric alerts on latency, error rate, or throughput for key spans like payment.stripe.charge. For dynamic patterns, use anomaly alerts to detect spikes or regressions without thresholds. Then jump into trace waterfalls to find the exact cause.
Why is this endpoint slower after the last deploy?
Sentry surfaces performance issues like N+1 queries, slow database calls, and uncompressed assets. Each issue includes example traces, spans, and stack traces to show where time is spent. Quickly identify root causes—whether it’s inefficient code, blocking I/O, or frontend bottlenecks.
Is this database call getting slower over time?
Use span metrics to track latency, throughput, and failure rate for specific operations like db.query.user_by_id. Analyze trends over time, broken down by service, operation, or environment. Use filters to investigate performance regressions and set alerts on critical spans.
How to debug errors in background jobs?
With Sentry tracing, background jobs are part of the full request flow—so you can see what triggered them, how long they ran, and where they failed. Spans show job timing, retries, and related service calls. When a job errors, trace context connects it to user actions or upstream issues
What’s causing errors in my agent runs?
Monitor and debug AI agents like OpenAI and Vercel with full visibility into how they interact with your app. See prompt flows, model responses, and tool calls. Catch failures in tools, malformed outputs, or high token usage. Link issues to triggering frontend/backend requests to understand impact.
Monitoring a production environment is always a challenge, with regular deployments, third party integrations, and the cloud resources we depend on - the number of issues that can fire from any one system increases the complexity of figuring out which service or team owns what.

And yes, it really is monthly. Ok, maybe the occasional twice a month, but for sure not like one of those daily ones that you just tune out after a while.
