Collection of high-performance CLI system tools written in Rust. Fast, safe, and production-ready utilities for system administration, monitoring, and analysis.
Powerful log file analyzer with pattern matching, statistics, and real-time monitoring.
Features:
- Parse multiple log formats (Common Log, JSON, custom patterns)
- Real-time log monitoring with
--follow - Statistical analysis (error rates, response times, traffic patterns)
- Filter by date range, log level, or regex patterns
- Generate reports in JSON, CSV, or Markdown
- Colorized output for better readability
Usage:
# Analyze access logs
loglyzer analyze /var/log/nginx/access.log
# Monitor logs in real-time
loglyzer follow /var/log/app.log --level ERROR
# Generate statistics
loglyzer stats /var/log/app.log --format json
# Filter by date range
loglyzer analyze app.log --from 2026-02-01 --to 2026-02-26System performance monitoring tool with resource tracking and alerting.
Features:
- Real-time CPU, memory, disk, and network monitoring
- Process-level resource tracking
- Historical data collection with configurable intervals
- Threshold-based alerting
- Export metrics to Prometheus format
- Beautiful TUI (Terminal UI) dashboard
Usage:
# Start monitoring with TUI dashboard
perfmon dashboard
# Monitor specific process
perfmon process --pid 1234
# Record metrics to file
perfmon record --interval 5s --output metrics.json
# Export to Prometheus
perfmon export --format prometheusAdvanced process management utility with batch operations.
Features:
- List processes with detailed information
- Filter by name, user, CPU, or memory usage
- Batch operations (kill, pause, resume)
- Process tree visualization
- Resource limits enforcement
- Generate process reports
Usage:
# List all processes
procman list
# Find processes by name
procman find nginx
# Kill processes using regex
procman kill --pattern "worker-.*"# Show process tree
procman tree --pid 1
# Monitor top consumers
procman top --by cpu --limit 10File system monitoring and security auditing tool.
Features:
- Monitor file changes in real-time
- Detect unauthorized modifications
- Calculate and verify file hashes
- Track file permissions and ownership changes
- Generate audit reports
- Integration with inotify (Linux) and FSEvents (macOS)
Usage:
# Watch directory for changes
fsaudit watch /var/www/html
# Verify file integrity
fsaudit verify --baseline baseline.json /etc
# Generate baseline snapshot
fsaudit snapshot /etc --output baseline.json
# Audit permissions
fsaudit audit /var --check-permissionsNetwork diagnostics and analysis toolkit.
Features:
- Port scanner with service detection
- TCP/UDP connectivity testing
- DNS lookup and reverse DNS
- HTTP/HTTPS endpoint testing
- SSL/TLS certificate information
- Bandwidth testing
- Network interface statistics
Usage:
# Scan ports
netutil scan localhost --ports 1-1000
# Test HTTP endpoint
netutil http https://api.example.com
# DNS lookup
netutil dns google.com
# SSL certificate info
netutil ssl https://example.com
# Interface statistics
netutil stats --interface eth0Disk space analysis and visualization tool.
Features:
- Recursive directory size calculation
- Find largest files and directories
- Duplicate file detection
- Interactive tree visualization
- Export reports in various formats
- Fast parallel scanning
Usage:
# Analyze directory
disklyzer analyze /home/user
# Find large files
disklyzer top /var --size 100MB
# Find duplicates
disklyzer duplicates /home --by hash# Visualize directory tree
disklyzer tree /var/log --depth 3# Clone repository
