What access logs reveal
Access records can show requested paths, methods, response statuses, client addresses, byte counts, and timestamps. Combined layouts add referrers and user agents; custom timing-enabled layouts may add duration.
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.
Access Log Analyzer FAQ
Can it analyze both Nginx and Apache access logs?
Yes. Their common and combined layouts are compatible for the supported request fields.
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.
