Analyzing Hardware Bottlenecks

The CPU, memory, I/O, and network resource usage of each node in openGauss are obtained to check whether these resources are fully used and whether any bottleneck exists.

  • CPU
    You can run the top command to check the CPU usage of each node in openGauss and analyze whether performance bottleneck caused by heavy CPU load exists.
  • Memory
    Run the top command to check the memory usage of each node in openGauss and analyze whether a performance bottleneck occurs due to high memory usage.
  • I/O
    You can run the iostat or pidstat command, or use openGauss health check tools to check the I/O usage and throughput on each node in openGauss and analyze whether performance bottleneck caused by I/O exists.
  • Network
    You can run the sar or ifconfig command to check the network status on each node in openGauss and analyze whether performance bottlenecks caused by network faults occur.
