Log Line Extractor
Paste a large log file and get just the ERROR, WARN and INFO lines isolated — a fast way to triage what actually matters in thousands of lines of routine DEBUG/TRACE noise without writing a grep command.
The Log Line Extractor module is already switched on below, with a sample loaded — paste your own text to replace it.
Frequently asked questions
Which log levels does it recognize?
Lines containing ERROR, WARN or INFO level markers (case-insensitive) are matched; DEBUG/TRACE-only lines are left out.
Does it work on very large logs?
Yes, extraction runs on a background Web Worker so pasting tens of thousands of lines doesn’t freeze the page.
Can I combine it with the IP or hash extractor?
Yes — turn those on alongside Log Lines to pull structured IOCs out of the same paste in one pass.
