What DescribeDeviceCPUMemoryUsage does on Ioacloud
AI agents call DescribeDeviceCPUMemoryUsage to retrieve information from Ioacloud without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
Mid | string | Yes | 设备唯一标识符; |
DomainInstanceId | string | — | 管理域实例ID，用于CAM管理域权限分配。若企业未进行管理域的划分，可直接传入根域"1"，此时表示针对当前企业的全部设备和账号进行接口CRUD，具体CRUD的影响范围限制于相应接口的入参。 |
Parameters from the server's own tool schema.
Why DescribeDeviceCPUMemoryUsage is rated Low
Even though DescribeDeviceCPUMemoryUsage only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
