Lambda Cloud GPU Instance Monitor

A lightweight command-line tool that continuously monitors Lambda Cloud for GPU instance availability and sends real-time notifications when instances become available.

Lambda's GPU instances (A100, H100, etc.) are often sold out. This script polls the Lambda API at a configurable interval and alerts you the moment a spot opens up — so you can grab it before it's gone.

Features

• Polls the Lambda Cloud API for all GPU instance types on a configurable interval (default: 60s)
• Detects newly available instances and highlights them in the terminal
• Sends native OS notifications (macOS, Linux, Windows) with a terminal bell when new instances appear
• Notification cooldown prevents spam for the same instance type (default: 5 min)
• Displays pricing, GPU count, RAM, storage, and available regions for each instance
• Color-coded terminal output for easy scanning
• Validates your API key on startup

Requirements

• Python 3.7+
• requests library

git clone http://github.com/Linqizhe07/Instance_monitor.git
cd Instance_monitor
pip install requests

Quick Start

1. Get an API key from Lambda Cloud → API Keys.

2. Run the script:

   python3 lambda_monitor.py

3. Enter your API key when prompted (or set it as an environment variable):

   export LAMBDA_API_KEY="your-api-key-here"
   python3 lambda_monitor.py

4. Press Ctrl+C to stop.

Configuration

Edit the constants near the top of lambda_monitor.py:

Variable	Default	Description
CHECK_INTERVAL	60	Seconds between each API poll
NOTIFY_COOLDOWN	300	Seconds before re-notifying for the same instance type

System Notifications

The script sends native desktop notifications via:

• macOS — osascript (with Glass sound)
• Linux — notify-send
• Windows — PowerShell toast notifications

If the notification subsystem is unavailable, the script falls back silently to terminal bell only.
