For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU. There also is a list of compute processes and few more options but my graphic card (GeForce 9600 GT) is not fully supported.

For linux, use nvidia-smi -l 1 will continually give you the gpu usage info, with in refresh interval of 1 second.
For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU.
For Intel GPU's you can use the intel-gpu-tools.
AMD has two options
fglrx (closed source drivers):
aticonfig --odgc --odgtAnd for mesa (open source drivers), you can use RadeonTop
sudo apt install radeontop radeontop
Source:GPU usage monitoring
You can use gpustat, which is a simple command-line script (wrapper for nvidia-smi) for querying and monitoring GPU status:
One small aspect where Linux is really lacking is GPU resource monitoring
Check NVIDIA GPU Usage
I didn't know how to find the GPU monitor on system monitor. Now I found mission center, that you can download from flathub, which gives you a simple performance + the GPU monitoring that I wanted. (Maybe system monitor has it, I'm just too dumb to find it.)
Simple tool to show GPU / CPU usage and temp?

Resource monitoring in general is not really a big deal for us in Tux-land. From great CLI tools, like all of the *tops (top, htop, bpytop, gotop, etc.) to great GUI tools (with KDE's newer resource monitor particularly REALLY great when it comes to presenting resource usage in a clean way to the user). But those really miss one essential aspect of resource monitoring, specially for desktop users. GPU usage.
Want to check how hard your $1000 graphics card is being stressed by that shiny new AAA game on Windows or in some sick benchmark or workflow? Just open Task Manager and check it, easy as that. Wanna do it on Linux? Well... get ready for a ride. Figure out what CLI tool works best for your GPU brand and go get'em at the terminal, champ! What, you want GUI tools? All you get is some small text in NVIDIA Settings for those that use NVIDIA.
It can get worse depending on what specific aspect of the GPU is being used. Want to check if your computer is properly using hardware encoding/decoding? Well, you're in luck (with CLI tools), nvidia-smi dmon and intel_gpu_top are really good. Unless you use AMD that is, since radeontop still doesn't have a way to expose GPU encoding/decoding.
I'm quite aware that developers are scarce and that this is definitely not a priority (and do I wish I knew enough code-fu to be able to do it myself), but it's kind of baffling that an integration with our DE's system resource monitoring tools doesn't exist for that particular aspect of the system. It's one of those many small papercuts you only realize hurts when you really need it.
EDIT: Yeah, I used a bad example for my point. Mangoud (specially with GOverlay) works great for monitoring your system during gaming or benchmarks. I meant more in the regular desktop usage sense of monitoring then in the gaming sense. Video editing or 3D modeling would be a better example of workflows where Mangohud wouldn't be the obvious answer for monitoring the resource usage.

+-----------------------------------------------------------------------------+I noticed high GPU usage on my GPU from nvidia-smi, but I saw that there are so many tasks utilizing GPU, I don't know who is causing it to be that high. I searched online for GPU profilers, but all I saw was nvidia-smi.
Does anyone know if there is a way to break down the % utilization of each task?
