## 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`

### 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:

`osmon`

#### Continuous Monitoring

If you want to continuously monitor your system's status with a specific refresh interval, use the `-i` flag with your desired interval in seconds:

```bash
osmon -i 5
```

### Binary Release Installation (Optional)

If you release a binary version of **osmon**, users can follow these steps:

1. Download the binary from the "Releases" section of your GitHub repository.

2. Move the binary to a directory in your PATH, for example, `/usr/local/bin`:

1. `mv osmon /usr/local/bin/osmon chmod +x /usr/local/bin/osmon`

## Compatibility

- **osmon** is compatible with Linux and macOS systems.
