Why SYS_ADMIN is required?

[Yvanll]

Recently, I found dcgm-exporter will enconter a runtime error: FATA[0000] Failed to watch metrics: Error watching fields: Host engine is running as non-root. And adding --cap-add=SYS_ADMIN with docker run or SYS_ADMIN in yaml can step over the error. I wonder what specific operation causes the issue?

The error was found in below scenarios with dcgm-exporter 3.6.0 without SYS_ADMIN

Device	Driver Version	CUDA Version
NVIDIA A30	535.54.03	12.2
NVIDIA L2	535.154.05	12.2
