큰 로그를 끌어다 놓으면 언제 몰렸는지 보여 주고, 급·정규식으로 좁혀 봅니다. 파일은 브라우저를 벗어나지 않습니다

Narrows a large log by time, level and regex, and shows you when the spikes happened first. Lines it cannot parse are kept, not dropped.
How to use it
- Paste the log or drop the file in
- Look at when it spiked first (bars per time bucket)
- Narrow by level (error/warn/info) and regex
- Copy just the lines that are left
Common questions
- Do I have to tell it the format?
- No. Each line is recognised on its own — ISO timestamps, syslog, nginx and JSON lines can be mixed together.
- Are unparsed lines dropped?
- Never. They stay as "time unknown" — the line a log tool throws away is usually the culprit.
- Is my log uploaded anywhere?
- No. Reading and filtering both finish inside your browser, so logs you could never upload elsewhere can be read here.
