Parameter	Description	Mandatory
[-i, --items]	Specifies the stress test item. EDP: Estimated Design Power TDP: Thermal Design Power	Yes
[-st, --st, --stress-time]	Specifies the time for the EDP and TDP stress tests. The value ranges from 60 to 604800, in seconds. This parameter must be used together with [-s, --stress] in the scenario where EDP and TDP stress test items are included.	No
[--skip-check]	Reports overtemperature alarms. This parameter is available only when items is set to edp or tdp.	No

Example

Example of setting the EDP stress test duration to 300s:

[***@***]# ascend-dmi -dg -i edp -s -st 300 -q
