i release a very small and ultra simple tool for monitoring NVIDIA GPUs across the network.
The network functionality is released today.
This very simple tool show you the main values from your GPU, like frequency, memory and so on. It can also display system values and finally - since today - you can use it in a network, by running a server with clients. This may be useful for render farms
Feel free for test and use
