How to Use Log Level Filter — Real-Time Log Parser & Severity Analyzer
How to Use the Log Level Filter
Step 1: Paste Your Log Output
Paste raw log text into the input box — one entry per line works best, though multi-line stack traces are preserved as-is.
Step 2: Detect Level Tokens
The tool scans each line for a severity token — ERROR, WARN/WARNING, INFO, DEBUG, or TRACE (including common aliases like FATAL, ERR, and VERBOSE) — and tags the line accordingly.
Step 3: Toggle Levels On or Off
Click the level chips to show or hide lines of that severity. The "No Level" chip controls whether lines without a recognizable level token (like plain status messages) are included.
Step 4: Copy or Download the Result
Use Copy or Download to export the filtered log, which preserves line counts so you can see exactly how many lines matched out of the total.
