osmon

osmon

osmon is a command-line tool written in Go that provides quick access to basic system information. With osmon, you can easily access details such as your host's IP address, system load, memory usage, logged-in users, and much more.

Features

• Displaying your host's name and IP address.
• Showing the current system load averages.
• Overview of memory usage statistics, including total memory, used memory, and available memory.
• Listing logged-in users and their respective terminals.

Applications

Monitoring After SSH Login

osmon is an ideal tool for a quick overview of a server's status upon SSH login. You can configure your shell to automatically run osmon every time you log in, providing an immediate snapshot of the server's status.

Example:

• Configure your .bashrc or .zshrc to run osmon upon every login, allowing you to immediately assess the state of the server.

Debugging

osmon can be an invaluable tool for debugging performance issues. By running osmon, you can quickly identify if high system load is caused by memory, CPU, or network activity.

Example:

• If you notice that your application is running slower than usual, you can use osmon to check if the system is under heavy load.

Installation

You can install osmon using the Go tool:

go install github.com/yourusername/osmon@latest

After installation, add the Go binary path to your system's PATH to access the osmon command from anywhere:

export PATH=$PATH:~/go/bin

Usage

osmon offers various command-line options for tailored usage. Below are the available flags and their descriptions:

• -h: Display help information. [...]
• -v: Display the version of the application. [...]
• -i or --interval: Set the interval for refreshing the display in seconds. [...]

Basic Usage

To simply display the system information, run the osmon command without any flags:
