Appearance

Monitor ​

The monitor module is used to record and view server performance data, including CPU, memory, disk I/O, and network traffic.

Monitor Settings ​

Enable Monitoring ​

After turning on the Enable Monitoring switch, the system will periodically collect performance data.

Retention Days ​

Set the retention time for monitoring data, default is 30 days. Data exceeding the retention time will be automatically cleaned up.

Clear Monitor Records ​

Click the Clear Monitor Records button to manually clear all historical monitoring data.

Monitoring Metrics ​

Load Average ​

System load reflects the busyness of the CPU:

  • 1-minute load: Average load over the last 1 minute
  • 5-minute load: Average load over the last 5 minutes
  • 15-minute load: Average load over the last 15 minutes

Load value reference:

  • Load < CPU cores: System running smoothly
  • Load = CPU cores: System running at full capacity
  • Load > CPU cores: System overloaded, may experience lag

CPU Usage ​

Displays CPU usage percentage, including:

  • User mode usage
  • System mode usage
  • Idle rate

Memory Usage ​

Displays memory usage:

  • Used memory
  • Available memory
  • Cache/Buffer

Disk I/O ​

Displays disk read/write speed:

  • Read speed (KB/s or MB/s)
  • Write speed (KB/s or MB/s)

You can select the disk device to monitor.

Network Traffic ​

Displays network interface traffic:

  • Send speed
  • Receive speed

You can select the network interface to monitor.

Time Range ​

Each monitoring chart supports selecting a time range:

  • Yesterday: View yesterday's data
  • Today: View today's data
  • Last 7 days: View data from the last week
  • Custom: Select any time range

Use Cases ​

Performance Analysis ​

Analyze server performance bottlenecks through monitoring data:

  • Sustained high CPU load: Consider optimizing programs or upgrading CPU
  • Insufficient memory: Consider adding memory or optimizing memory usage
  • High disk I/O: Consider using SSD or optimizing database queries
  • Insufficient network bandwidth: Consider upgrading bandwidth

Troubleshooting ​

When problems occur, view historical monitoring data to locate the time and cause of the problem.

Capacity Planning ​

Based on historical data trends, predict future resource needs and plan for expansion in advance.

Notes ​

  • Monitoring data will occupy some disk space
  • The longer the retention days, the more space it occupies
  • It is recommended to set appropriate retention days based on actual needs
