Zenith

In terminal graphical metrics for your *nix system written in Rust

Features

• Optional CPU, Memory, Network, and Disk usage charts
• Quick glances at Disk free space, NIC IP addresses, CPU frequency
• Highlight top users of CPU, Memory, & Disk
• Battery percentage, time to charge or discharge, power used
• A top-like filterable process table that includes per process disk usage
• Change process priority
• Zoomable chart views (with support to scroll back in time)
• Managing processes with signals
• Performance data saved between runs
• GPU Utilization Metrics for NVIDIA GPUs (with --features nvidia)

Planned Features

• CPU steal percentage and general virtualization awareness
• Sensor Temperature charts
• Per process network usage (Linux)
• Messaging about adverse system events, like errors in kernel ring buffer (Linux)
• Docker support
• ZFS (pool status)
• GPU utilization metrics for AMD GPUS
• Disk metrics like IO ops / latency
• Support Memory pressure

Current Platforms

• Linux
• MacOS

Planned Platforms

• BSD (OpenBSD/FreeBSD)
• Perhaps Redox OS.

Installation

Binary

Download one of the compiled releases.

Homebrew

brew install zenith

Building

This 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

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:

    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>        Height of CPU/Memory visualization. [default: 10]
        --db <STRING>             Database to use, if any. [default: ~/.zenith]
    -d, --disk-height <INT>       Height of Disk visualization. [default: 10]
    -n, --net-height <INT>        Height of Network visualization. [default: 10]
    -p, --process-height <INT>    Min Height of Process Table. [default: 8]
    -r, --refresh-rate <INT>      Refresh rate in milliseconds. [default: 2000]

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:
