+# Enable GPU monitoring
+
+GPU monitoring is a new feature implemented in Nezha Monitoring v0.17.x. Before using the feature, please check you Dashboard version is higher than v0.17.2 and Agent version is higher than v0.17.0.
+
+## Enable
+
+### From Command-Line Flag
+
+Append the `--gpu` flag to the Agent argument. For example:
+
+```bash
+/opt/nezha/agent/nezha-agent -s example.com:5555 -p example --gpu
+```
+
+### From configuration file
+
+Execute the following command to modify Agent configuration to enable GPU monitoring.
+
+```bash
+/opt/nezha/agent/nezha-agent edit
+```
+
+In the returned interactive menu, choose to enable GPU monitoring.
+
+## Enable GPU utilization monitoring
+
+GPU model and GPU utilization are two different monitor items, which uses different approaches to obtain their value.
+
+Windows and macOS supports getting GPU utilization without extra dependencies, and support multiple graphics card brands.
+
+Linux distros support only NVIDIA and AMD cards and need to install extra dependencies.
+
+Below are the instructions on how to enable GPU utilization monitoring on Linux for NVIDIA / AMD graphics cards.
+
+### NVIDIA
+
+NVIDIA cards need the `nvidia-smi` utility to get GPU utilization. This utility is included in the official driver by default.
+
+If you use unofficial drivers like `nouveau`, then it's not possible to get GPU utilization.
+
+### AMD
+
+AMD cards need to install the official `amdgpu` driver and the `rocm-smi` utility.
+
+Mainstream distros have already packaged `rocm-smi`, below are commands to install the utility on these distros:
+
+```bash
+# Arch Linux
+pacman -Sy rocm-smi-lib
+
+# Debian / Ubuntu
+apt install rocm-smi
+
+# Fedora / RHEL 8+
+dnf install rocm-smi
+```
+
+If your distro doesn't have the package, then you will need to compile `rocm_smi_lib` manually.
+
+Required dependencies：`git` `cmake` `gcc`
+
+First, clone the git repository of `rocm_smi_lib`:
+
+```bash
+git clone https://github.com/ROCm/rocm_smi_lib
+```
+
+Then compile the libraries and install them on your system.
+
+```bash
+cd rocm_smi_lib
+mkdir -p build
+cd build
+cmake ..
+make -j $(nproc)
+# Install library file and header; default location is /opt/rocm
+make install
+```
