Zen monitor

Zen monitor is monitoring software for AMD Zen-based CPUs.

It can monitor these values:

• CPU Temperature
• CPU Core (SVI2) Voltage, Current and Power
• SOC (SVI2) Voltage, Current and Power
• Package and Core Power (RAPL)
• Core Frequency (from OS)

Dependencies

• zenpower driver - For monitoring CPU temperature and SVI2 sensors
• MSR driver - For monitoring Package/Core Power (RAPL)

Follow zenpower README.md to install and activate zenpower module. Enter sudo modprobe msr to enable MSR driver.

Building

Make sure that GTK3 dev package and common build tools are installed.

make

Launching

You can launch app by sudo ./zenmonitor, or you can install it to your system and then launch it from your OS menu.

Note: Because superuser privileges are usually needed to access data from MSR driver, you need to launch zenmonitor as root for monitoring CPU power usage (RAPL). Alternatively, you can set capabilities to zenmonitor executable: sudo setcap cap_sys_rawio,cap_dac_read_search+ep ./zenmonitor

Command line arguments

--coreid - Display core_id instead of core index

Installing

By default, Zenmonitor will be installed to /usr/local.

sudo make install

To add menu item for launching zenpower as root (Polkit is required):

sudo make install-polkit

Uninstalling

sudo make uninstall

Setup on ubuntu

First follow installation instructions on zenpower Then:

sudo modprobe msr
sudo bash -c 'echo "msr" > /etc/modules-load.d/msr.conf'
sudo apt install build-essential libgtk-3-dev git
cd ~
git clone https://github.com/ocerman/zenmonitor
cd zenmonitor
make
sudo make install
sudo make install-polkit

Setup on Arch

You may use the AUR package zenmonitor-git to install via traditional method or using an AUR helper (like yay)
