Log Pattern Extractor

A log pattern extractor: paste raw log lines and cluster them into templates by masking variable tokens (timestamps, IPs, UUIDs, numbers, durations, hex, ids and key=value values), then see each template with its frequency, percentage and an example — sorted by count with a min-count filter.
