## Installation
### Binary
Download one of the compiled [releases](https://github.com/bvaisvil/zenith/releases).
### Debian/Ubuntu based Linux distributions (64-bit)
The latest 64-bit deb packages are available [here](https://github.com/bvaisvil/zenith/releases) and require distributions based on Debian >= 9 or Ubuntu >= 16.04
You can also install and update the `.deb` packages we publish in our GitHub releases page using [deb-get](https://github.com/wimpysworld/deb-get).
First install `deb-get` using these commands in a terminal:
```bash
sudo apt install curl
curl -sL https://raw.githubusercontent.com/wimpysworld/deb-get/main/deb-get | sudo -E bash -s install deb-get
```
Then install zenith using the following command in terminal:
```bash
deb-get install zenith
```
Once zenith is installed it can be kept upto date using:
```bash
deb-get update
deb-get upgrade
```
### Arch Linux
zenith is available in the [extra repository](https://archlinux.org/packages/extra/x86_64/zenith/) and can be installed with [pacman](https://wiki.archlinux.org/title/Pacman):
```bash
pacman -S zenith
```
There are also packages available in the AUR: 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:
```bash
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 preferred AUR package: ```yay -S zenith-git``` (will track the latest git revision)
### Homebrew
```bash
brew install zenith
```
### Cargo
```
cargo install --git https://github.com/bvaisvil/zenith.git
```
For NVIDIA GPU support, install with feature `nvidia`:
```
cargo install --features nvidia --git https://github.com/bvaisvil/zenith.git
```
## Building
### Prerequisites
Building requires rust version >= 1.40 and libclang development packages.
#### Rust:
Install from your preferred package manager or preferrably use [rustup.rs](https://rustup.rs/)
#### [Clang](https://clang.llvm.org/) development packages:
- Ubuntu/Debian:
`sudo apt-get install libclang-dev`
- CentOS/RHL/Fedora
`sudo [yum/dnf] install clang`
Zenith builds under rustc version >= 1.40.0.
```
cd zenith
cargo build --release
```
For NVIDIA GPU support, build with feature `nvidia`:
```cargo build --release --features nvidia```
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 Min Percent Height of CPU/Memory visualization. [default: 17]
--db Database to use, if any. [default: ~/.zenith]
-d, --disk-height Min Percent Height of Disk visualization. [default: 17]
-n, --net-height Min Percent Height of Network visualization. [default: 17]
-p, --process-height Min Percent Height of Process Table. [default: 32]
-r, --refresh-rate Refresh rate in milliseconds. [default: 2000]
-g, --graphics-height 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.
For example: ```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:
