HAProxy Log Analyzer
HAProxy Log Analyzer is built for operations, engineering, and incident review. Open a log file locally to inspect status codes, traffic patterns, abnormal paths, crawler activity, and noisy clients.
Why local haproxy log analyzer matters
Production logs often contain client IPs, request paths, query strings, and internal endpoints. Local parsing keeps sensitive log data inside the browser while still giving you charts, filters, and threat signals.
Core Capabilities
- Drag and drop large access logs for fast local parsing and visualization.
- Filter by status class, request method, time range, and full-text search.
- Spot heavy paths, suspicious scans, crawler traffic, and traffic spikes quickly.
FAQ
Does HAProxy Log Analyzer upload my logs?
No. Parsing, aggregation, and filtering happen locally in the browser and your raw logs are not sent to a remote server.
What can HAProxy Log Analyzer measure?
It can surface traffic timelines, status distributions, PV and UV, top paths, slow requests, bandwidth, referers, user agents, and threat signals.
What investigations is HAProxy Log Analyzer useful for?
It is useful for reviewing crawler requests, 404 pages, 5xx failures, hot URLs, and suspicious scan paths so you can find traffic and reliability issues faster.
