• Optional CPU, Memory, Network, and Disk usage histograms
• Quick glances at Disk free space, NIC IP addresses, CPU frequency
• A top like process table that includes per process disk usage
• Different histogram views (5 minutes, 1 hour, etc)
• Managing processes (signals, nice, etc)
• Saving performance data

• Sensor Temperature histograms
• Per process network usage (Linux)
• Messaging about adverse system events, like errors in kernel ring buffer (Linux)
• Docker support

• Linux
• MacOS

• Other BSD systems may work, I have not tested.
• Perhaps Redox OS.

Download one of the compiled releases.

This builds under rustc version 1.39.0.

cd zenith
cargo build --release

Running with no arguments starts zenith with the default visualizations for CPU, Disk, and Netowrk and a refresh rate of 2000 ms (2 seconds). These can be changed with command line parameters:

    zenith [OPTIONS]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

OPTIONS:
    -c, --cpu-height <INT>        Height of CPU/Memory visualization. [default: 10]
    -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 Will remove the CPU histogram.

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 histograms. Arrow keys (←/→) move forward/backward in time. Back tick (`) resets the histogram to current time and max zoom. Using this you can create the layout you want.
