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/debek/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
