When to use this skill
Use this skill when the user wants to:
- Run system diagnostics or health checks
- Manage Docker containers (status, logs, health, compose)
- Inspect running processes, ports, or resource hogs
- Analyze log files for errors, patterns, or frequency
- Check HTTP endpoint availability or port status
- Get a quick one-command system overview
Commands
Quick Diagnostics (start here)
# Full system health report — CPU, memory, disk, Docker, ports, errors, top processes
python3 skills/agentic-devops/devops.py diag
Docker Operations
# Container status overview
python3 skills/agentic-devops/devops.py docker status
# Tail container logs with pattern filtering
python3 skills/agentic-devops/devops.py docker logs <container> --tail 100 --grep "error|warn"
# Docker health summary (running, stopped, unhealthy)
python3 skills/agentic-devops/devops.py docker health
# Docker Compose service status
python3 skills/agentic-devops/devops.py docker compose-status --file docker-compose.yml
Process Management
# List processes sorted by resource usage
python3 skills/agentic-devops/devops.py proc list --sort cpu
# Show ports in use
python3 skills/agentic-devops/devops.py proc ports
# Detect zombie processes
python3 skills/agentic-devops/devops.py proc zombies
Log Analysis
# Analyze log file for error patterns
python3 skills/agentic-devops/devops.py logs analyze /var/log/syslog --pattern "error|fail|critical"
# Tail log file with highlighted patterns
python3 skills/agentic-devops/devops.py logs tail /var/log/app.log --highlight "ERROR|WARN"
# Frequency analysis of log patterns
python3 skills/agentic-devops/devops.py logs frequency /var/log/app.log --top 20
Health Checks
# Check HTTP endpoint health
python3 skills/agentic-devops/devops.py health check https://myapp.com/healthz
# Scan specific ports
python3 skills/agentic-devops/devops.py health ports 80,443,8080,5432
# System resource health (CPU, memory, disk)
python3 skills/agentic-devops/devops.py health system
Requirements
- Python 3.8+ (stdlib only, no external dependencies)
- Docker CLI (optional — Docker sections degrade gracefully if not installed)
- Standard Unix utilities (ps, ss/netstat)
