ALM-1101320 The NPU Usage Exceeds the Threshold


FusionSphere OpenStack periodically (every 5 minutes by default) checks the NPU usage in a host group. This alarm is generated when the NPU usage reaches 85% in the hosts.

This alarm is cleared when the NPU usage in the hosts is reduced to 70%.


Alarm ID

Alarm Severity

Auto Clear







Fault Location Info

  • aggregate_id: specifies the ID of the host group where NPU is located.
  • npu_type: specifies the type of the NPU.

Additional Info

  • Service: specifies the service for which the alarm is generated.
  • MicroService: specifies the microservice for which the alarm is generated.
  • aggregate_name: specifies the name of the host group where NPU is located.
  • npu_total: specifies the total number of NPUs.
  • npu_used: specifies the number of used NPUs.
  • threshold: specifies the NPU threshold.

Impact on the System

VMs with NPU installed may fail to create due to insufficient resources of NPU resources.

Possible Causes

The NPU usage is too high in the host group.


  1. Obtain the NPU card type and host group information based on the alarm information. You are advised to add NPU cards of the same type to the host group for capacity expansion.
  2. After the NPU usage drops below 70%, check whether this alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 3.

  3. If any of the preceding operations fails, contact technical support for assistance.
