Apache access-log analysis
Common and Combined Log Format records provide request paths, client addresses, status codes, and byte counts. Combined logs can also supply referrers and user agents.
Apache error-log investigation
Recognized error records expose their timestamp, severity, client, and message. Mixed malformed lines are skipped without stopping the rest of the analysis.
Private, local log analysis
Files are sliced and processed by a Web Worker in your browser. ToolsWeave does not upload log content, filenames, IP addresses, URLs, messages, or stack traces. Exports are also generated locally.
Apache Log Analyzer FAQ
Which Apache formats work?
Common Log Format, Combined Log Format, and recognizable Apache error-log entries are supported.
Can Apache logs show response time?
Only when a compatible custom access format records duration; standard Common and Combined formats do not.
Are log files uploaded?
No. Analysis runs in a browser Web Worker and the selected file is read in local chunks.
Can I analyze a large log file?
Yes. File input is chunked and aggregate counters are built incrementally. Full-file searches return 100 records per page and rescan the source when filters or pages change. Actual limits depend on the browser, individual entry size, and device.
