What Can I Do If the CPU Usage Is High?

What Can I Do If the CPU Usage Is High?

If the CPU usage is high, perform the following operations:
  1. Check whether the CPU usage keeps increasing or increases instantly. An instant increase in the CPU usage may indicate that an operation has just been performed, for example, a card has just been started, information about all optical modules has been queried, or the volume of traffic has increased instantly. This situation does not affect the device operation.
  2. Check which task processes consume the most CPU resources and analyze the tasks.
  3. Check log information and alarm information to determine whether a hardware fault alarm is generated.
  4. Analyze log information and alarm information to determine whether an interface frequently alternates between Up and Down states. If so, check whether the optical module of the interface is faulty or a non-Huawei-certified optical module is used. Additionally, analyze the configuration and traffic volume of the interface.
  5. Check whether network management operations are frequently performed on the device.
  6. Check whether flapping occurs with STP or routing protocols.
  7. Check whether the network topology changes and whether a loop exists on the network.
  8. Check whether malicious attacks are in progress.
