lagraph

lagraph is a command-line utility that can be used to draw a ping graph over time.

Features

Bars drawn using Unicode or ASCII character, supporting "half characters" for increased precision
True-color output with configurable saturation
Setting ping interval and/or count
Optional short or long timestamp

Use cases

Monitoring your connection quality and stability over time.
- This is especially useful when using Wi-Fi or mobile connections such as 4G.

Installation

Using `cargo`

If you already have Rust installed, you can use Cargo to build and install lagraph:

bash cargo install lagraph

Usage

Use lagraph --help for a full list of command-line options.

Examples

Ping an host at the default interval (0.5 seconds):

bash lagraph <host>

Ping an host every 5 seconds, displaying a short timestamp on the left:

bash lagraph -i 5 -t short <host>

Ping an host with a maximum displayable ping value of 100 milliseconds and remove colors from the output:

bash lagraph -M 100 -C none <host>

Setting true-color output by default

To use true-color output by default, you need to set the environment variable COLORTERM to truecolor. You can make this permanent by adding the following line to your shell startup file (such as ~/.bashrc or ~/.zshrc):

bash export COLORTERM="truecolor"

On Windows, this can be done using the following commands depending on your shell:

bat :: cmd.exe (Batch) set COLORTERM=truecolor

```powershell

PowerShell

$env:COLORTERM="truecolor" ```

Note that not all terminals support true-color terminal output; see this gist for more information. Windows 10 supports true-color terminal output since the Creators Update (version 1703).
