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
