LogLens

Log file analyzer with anomaly detection. Auto-detects 5 timestamp formats (ISO 8601, syslog, Apache, datetime, compact). Extracts log levels and source modules. Finds error spikes (5+ errors in 1-minute windows), suspicious time gaps (10+ minutes silence), and repeated message spam. Filter by level or regex pattern. Slice through massive log files in seconds. HTML reports with bar charts, JSON output for pipelines. CI/CD ready. Zero dependencies. Single Python file.
