Why Server Monitoring is Critical

Server monitoring is the foundation of maintaining a reliable and high-performing web infrastructure. Without proper monitoring, issues can go undetected until they cause significant downtime, data loss, or poor user experience. Effective monitoring helps identify problems before they impact users, optimize resource usage, and ensure your applications run smoothly 24/7.

Key Metrics to Monitor

Types of Server Monitoring

1. Infrastructure Monitoring

Focuses on hardware and system-level metrics.

• Hardware Health: Temperature, fan speeds, power supply
• System Resources: CPU, memory, disk, network
• Operating System: Process monitoring, log analysis
• Services: Critical service availability

2. Application Performance Monitoring (APM)

Monitors application-specific metrics and user experience.

• Response Times: Page load speeds
• Error Rates: Application failures and exceptions
• Throughput: Requests per second
• User Experience: Real user monitoring (RUM)

3. Network Monitoring

Tracks network performance and connectivity.

• Bandwidth Usage: Data transfer rates
• Latency: Network delays and ping times
• Packet Loss: Network reliability
• Security: Intrusion detection and prevention
