Frequently Asked Questions
How do I find the real error?
Group by message signature: 10,000 lines collapse to 20 unique errors ranked by count. Fix the top one — cascades often share a root cause.
Time clustering?
Errors bucketed per minute reveal onsets (deploy at 3:04 → errors at 3:05). Correlate spikes with deploys and cron schedules.
Large log files?
Hundreds of thousands of lines parse locally; gigabyte archives need sampling or CLI tools. Filter by level first to shrink noise.
Are logs uploaded?
No — parsing runs locally in your browser. Logs never leave your device — still sanitize secrets before sharing exports.
