How do i get the fields using golang?

[vickyvikas7988]

Team,

there is no samples available in the repository to retrieve the information of fields.

Lets say I want to extract DCGM_FI_DEV_PCIE_LINK_WIDTH for all the GPUs on the server.

Can someone help me how to extract this value?

It might be simple but I am struggling to retrieve it using go-lang

go-dcgm/pkg/dcgm/const.go

Line 132 in 6d8fa5f

DCGM_FI_DEV_PCIE_LINK_WIDTH = 238

@vickyvikas7988,

You could see an example here:

go-dcgm/pkg/dcgm/device_status.go

Line 73 in 6d8fa5f

func latestValuesForDevice(gpuId uint) (status DeviceStatus, err error) {

In general, to get any field value you first need to:

1. Initialize dcgm client
2. Create group
3. Add devices to the group
4. Create fields group
5. Add fields to the group
6. Enable watch for the field group and device group
7. Get the latest values for the field group and the device group

I am unable to see below fields in https://github.com/NVIDIA/go-dcgm/blob/6d8fa5f863f805dd92c66a94ce5e5b037a24959c/pkg/dcgm/const.go file

DCGM_CLOCKS_THROTTLE_REASON_HW_SLOWDOWN
DCGM_CLOCKS_THROTTLE_REASON_SW_THERMAL
DCGM_CLOCKS_THROTTLE_REASON_HW_THERMAL
DCGM_CLOCKS_THROTTLE_REASON_HW_POWER_BRAKE

How do I use it?

go-dcgm/pkg/dcgm/dcgm_fields.h

Line 123 in 6d8fa5f

#define DCGM_CLOCKS_THROTTLE_REASON_HW_SLOWDOWN 0x0000000000000008LL
