How do I get session replay for a production bug?

To get a useful session replay for a production bug, you usually need three things in place:

1. A session replay tool
2. A way to identify the affected user/session
3. A way to capture enough context around the bug

1) Use a session replay product

Common options:

• LogRocket
• Datadog Session Replay
• FullStory
• Sentry Replay
• OpenReplay
• PostHog Session Replay

These tools record user interactions in the browser and let you inspect the timeline around the bug.

2) Make sure replay is enabled in production

In your frontend app, install and initialize the tool in production builds only if needed, or in a sampled way. Typical setup includes:

• recording DOM interactions
• capturing console errors
• capturing network requests
• masking sensitive inputs

Important:

• Do not record passwords, credit card fields, or secrets
• Enable PII masking/redaction
• Check legal/privacy requirements and get user consent if required

3) Correlate the bug with a session

When the bug happens, you need a way to find the exact replay. Useful identifiers:

• user ID
• session ID
• request ID / trace ID
• timestamp
• browser / device info
• error message
• route/page name

Best practice:

• When an error occurs, log it with a session ID
• Include the same session ID in your backend logs and error tracking
• Add a “Report a problem” button that sends the current session/user context

4) Capture the bug trigger

To make the replay easy to find:

• log frontend errors to your error tracker
• tag events before and after key actions
• capture breadcrumbs
• include route changes and API failures

For example, in Sentry/Datadog/LogRocket you can often attach a replay to an exception automatically.

5) Reproduce and inspect

Once you have the session:

• open the replay
• jump to the timestamp where the error occurred
• inspect network calls and console errors
• check what the user clicked/typed before the issue
• compare with backend logs

6) If you don’t already have replay enabled

Then you can’t retroactively get a replay for past users unless your platform already recorded it. In that case:

• enable replay now
• ask affected users to reproduce the issue
• rely on logs, traces, and analytics until you have a captured replay

Quick recommendation

If you want the fastest path:

• use Sentry Replay if you already use Sentry
• use Datadog Session Replay if you already use Datadog APM/logs
• use LogRocket if you want a dedicated frontend debugging workflow

If you want, I can also give you:

• a setup guide for your framework (React, Next.js, Vue, Angular)
• a privacy-safe replay configuration
• or a troubleshooting checklist for production bugs
