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)
