logpeek

View, tail, filter, search, and analyze log files from the command line. Think tail -f meets grep with stats and JSON output.

Install

pip install logpeek-cli

Features

• Auto-detect log formats: syslog, nginx, Apache, JSON lines, generic timestamped
• Log level detection: ERROR, WARNING, INFO, DEBUG with colorized output
• Regex search: with context lines (-A, -B, -C) like grep
• Time range filtering: parse timestamps from any common format
• Statistics: level distribution, lines per hour, error rate
• Field extraction: IPs, URLs, emails, HTTP status codes
• Top N analysis: most frequent values for any extractable field
• JSON output: --json flag on every command
• Stdin support: pipe logs from other commands
• No heavy deps: just Python + Click

Stdin / Pipelines

cat /var/log/syslog | logpeek filter --level error
kubectl logs pod-name | logpeek stats
docker logs container | logpeek search "timeout" -C 2
journalctl -u nginx | logpeek top --field ip -n 20
