Download one of the compiled releases.
The latest 64-bit deb packages are hosted on bintray and require distributions based on Debian >= 9 or Ubuntu >= 16.04
Import the bintray public key:
wget 'https://bintray.com/user/downloadSubjectPublicKey?username=bintray' -q -O- | sudo apt-key add -
Add the following line to /etc/apt/sources.list.d/zenith.list:
deb [arch=amd64] https://dl.bintray.com/bvaisvil/debian stable main
Then you can install/update the 'zenith' package:
sudo apt-get update sudo apt-get install zenith
Three packages for zenith are available in AUR: zenith, zenith-git and zenith-bin
The zenith-bin package uses the deb package mentioned in previous section and can be used to avoid building the package from source. The first two depend on rust/cargo and it is recommended to install the rustup package from AUR instead of the rust package from official repositories. This allows for easy installation of rust components as per what rust officially documents. You will need to install a toolchain separately with rustup so use something like:
yay -S rustup rustup toolchain install stable rustup default stable
Change the 'stable' toolchain above to beta/nightly/... if you have some specific preference. After this install the zenith or zenith-git package (latter will track the latest git revision):
yay -S zenith
brew install zenith
This builds under rustc version >= 1.40.0.
cd zenith cargo build --release
For NVIDIA GPU support, build with feature
The minimum supported NVIDIA driver version is 418.56 There is also a Makefile that detects the presence of NVIDIA driver on the current system and builds the appropriate flavor on Linux. ```make && sudo make install``` If for some reason the Makefile incorrectly detects NVIDIA driver installation or in case of a broken installation (e.g. libnvidia-ml.so.1 present but no libnvidia-ml.so) then explicitly skip it using the `base` target: ```make base && sudo make install``` The default installation path is `/usr/local` so `make install` requires root privileges above. To install in a custom location use PREFIX like below: ```make && make install PREFIX=$HOME/zenith``` There is also an 'all' target in the Makefile that will build both the flavors on Linux, if NVIDIA driver is detected, and 'make install' will then copy a wrapper 'zenith' script that chooses the appropriate binary at runtime. ### Static build The make file provides for building fully static versions on Linux against the musl C library. It requires musl-gcc to be installed on the system. Install "musl-tools" package on debian/ubuntu derivatives, "musl-gcc" on fedora and equivalent on other distributions from their standard repos. Use the target "linux-static" to build it. This will create a tarball containing the executable accompanied with file containing sha256 sum. NVIDIA drivers normally do not ship with static versions of the libraries, so the static build skips that configuration. However, if you somehow get hold of static NVIDIA libraries or are okay for dynamic linking for that executable, then you can explicitly set the BUILD_NVIDIA flag to true: ```make linux-static BUILD_NVIDIA=true``` ### Building with NVIDIA support in a virtual environment If one needs to build with NVIDIA support in a virtual environment, then it requires some more setup since typically the VM software is unable to directly expose NVIDIA GPU. Unlike the runtime zenith script, the Makefile has been setup to detect only the presence of required NVIDIA libraries, so it is possible to build with NVIDIA support even when without NVIDIA GPU. Install the nvidia driver package as per the distribution recommended way. For example in Ubuntu < 18.04 add the NVIDIA PPA (https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa) and install the nvidia-430 package. For newer versions install nvidia-driver-440/450 package. After that disable the actual use of the driver using "sudo prime-select intel". Then while building with Makefile you will need to explicitly add the NVIDIA library path to LD_LIBRARY_PATH. For instance on Ubuntu and derivatives, something like:
export LD_LIBRARY_PATH=/usr/lib/nvidia-430 make && sudo make install
### Building deb package Debian package support is present in the source tree. Install devscripts package and use standard options like "debuild -b -uc -us" to build an unsigned deb package in the directory above. In a virtual environment build, LD_LIBRARY_PATH can be explicitly set like: ```debuild -eLD_LIBRARY_PATH=/usr/lib/nvidia-430 -b -uc -us``` Cargo can be installed from the repositories or the standard rustup way. Latter would be normally recommended if one needs to do anything more than just building in a virtual environment. For that case $HOME/.cargo/bin should be in PATH and mark PATH so that debuild does not sanitize it: ```debuild -ePATH -eLD_LIBRARY_PATH=/usr/lib/nvidia-430 -b -uc -us``` Clean up using "./debian/rules clean" rather than "make clean" to clear debian build files too. ## Usage Running with no arguments starts zenith with the default visualizations for CPU, Disk, and Network and a refresh rate of 2000 ms (2 seconds). These can be changed with command line parameters: ```USAGE: zenith [FLAGS] [OPTIONS] FLAGS: --disable-history Disables history when flag is present -h, --help Prints help information -V, --version Prints version information OPTIONS: -c, --cpu-height <INT> Min Percent Height of CPU/Memory visualization. [default: 17] --db <STRING> Database to use, if any. [default: ~/.zenith] -d, --disk-height <INT> Min Percent Height of Disk visualization. [default: 17] -n, --net-height <INT> Min Percent Height of Network visualization. [default: 17] -p, --process-height <INT> Min Percent Height of Process Table. [default: 32] -r, --refresh-rate <INT> Refresh rate in milliseconds. [default: 2000] -g, --graphics-height <INT> Min Percent Height of Graphics Card visualization. [default: 17]
The graphics-height option only applies when NVIDIA GPU support has been enabled.
Don't want a section? Remove it by setting the height to 0.
zenith -c 0 removes the CPU chart.
Up/down arrow keys move around the process table. Return (enter) will focus on a process. Tab switches the active section. Active sections can be expanded (e) and minimized (m). +/- (or =/-) will zoom in / out all of the charts. Arrow keys (←/→) move forward/backward in time. Back tick (`) resets the chart to current time and max zoom. Using these options you can create the layout you want.
In zenith 'h' key will show this help:
