Workflow: Health Check

Phase 1: Quick Overview

Step 1.1: System Overview

Use resource_overview to get:
- OS information
- Uptime
- Load averages
- Quick resource summary

Phase 2: Detailed Analysis

Step 2.1: CPU Analysis

Use resource_cpu to check:
- Core count
- Usage percentage
- Temperature
- Processes per core

Step 2.2: Memory Analysis

Use resource_memory to check:
- Total/used/free RAM
- Swap usage
- Memory pressure

Step 2.3: Disk Analysis

Use resource_disk to check:
- Partition usage
- Available space
- I/O statistics

Step 2.4: Network Analysis

Use resource_network to check:
- Interface status
- Bandwidth usage
- Active connections

Phase 3: Process Investigation

Step 3.1: Top Processes

Use resource_processes to identify:
- CPU-heavy processes
- Memory-heavy processes
- Zombie processes

Alert Thresholds

| Metric | Warning | Critical | |--------|---------|----------| | CPU Usage | >70% | >90% | | Memory Usage | >80% | >95% | | Disk Usage | >80% | >95% | | Load Average | >cores | >cores×2 |

Best Practices

✅ GOOD:

• Regular monitoring
• Set up alerts
• Track trends over time
• Document baseline metrics

❌ BAD:

• Ignore warnings
• No monitoring in production
• React only to outages
• No capacity planning

Checklist

• [ ] CPU usage normal (<70%)
• [ ] Memory available (>20% free)
• [ ] Disk space sufficient (>20% free)
• [ ] Network interfaces up
• [ ] No zombie processes
• [ ] Load average acceptable
