Unfortunately, at this moment GPU publishers are not supported for linux. I just want to make it clear that it’s a publisher limitation and not a metrics framework limitation. We don’t own support of or testing for GPA publishers.
GPU publishers team suggested this option:
Publishers will provide metrics on the systems where Metrics Discovery API is available. Mesa driver that is normally used on Linux systems does not support this API.Metrics Discovery API is supported by VPG gfx driver. In theory if customer install VPG gfx driver on Linux system then publishers should work.
