Hi , regarding the function tsapiGetNvLinkLinkStatus, in a deeper level, how is the NvLink status obtained? Is it obtained from the GPU via nvidia driver ?

DCGM uses the NSCQ library, which must be installed separately from DCGM and is bound to the driver version.

Thanks @nikkon-dev , got 1 more, How about the pulse test plugin, https://github.com/NVIDIA/DCGM/blob/7e1012302679e4bb7496483b32dcffb56e528c92/dcgmi/Diag.cpp#L642

what is the actual dependent library that provides the pulse test?
