VM Performance Monitor & Controller

A cross-platform desktop application for monitoring and managing virtual machines over SSH.

Overview

VM Performance Monitor & Controller provides a modern GUI for administrators and developers to connect to a VM, view live system metrics, inspect running processes, execute shell commands, and manage processes remotely.

The application is built with:

• Python
• CustomTkinter for the desktop interface
• Paramiko for SSH communication
• psutil for local dependency support

Features

Real-Time Monitoring

• Live CPU usage monitoring
• Live memory usage monitoring
• Color-coded resource indicators
• Periodic refresh of remote system data

Process Management

• View remote process list
• Sort processes by CPU usage
• Kill processes gracefully
• Force kill processes when needed
• Protection against terminating critical system processes

Remote Command Execution

• Execute shell commands on the VM
• Support for sudo commands with password prompt
• Background execution for long-running commands
• Output and error logging in the GUI

Connection Management

• SSH connection dialog
• Save connection settings locally
• Reconnect and disconnect controls
• Connection status indicator

System Details

• VM OS information
• Kernel version
• Uptime
• CPU details
• Disk usage
• Network address information

Architecture

The application uses a secure client-server model over SSH:

• VMConnection handles SSH connectivity and command execution
• VMMonitor builds the main interface and orchestrates updates
• CommandPanel provides a terminal-like interface for remote commands
• Background threads keep the UI responsive during remote operations

Requirements

• Python 3.10+ recommended
• SSH access to a Linux-based VM
• The following Python packages:
  • paramiko
  • psutil
  • customtkinter

Installation

pip install paramiko psutil customtkinter

Usage

1. Run the application:

python main.py

2. Enter the VM host/IP, SSH port, username, and password.
3. Connect to the VM.
4. Monitor system metrics, manage processes, or run commands from the dashboard.

Security Notes

• The app uses SSH for encrypted remote communication.
• Do not store credentials on shared systems unless you trust the environment.
• Be careful when using force kill or remote command execution.
