Memory Monitor

A lightweight Python utility that monitors system memory usage and alerts when memory thresholds are exceeded.

Features

• Monitors system memory usage in real-time
• Alerts when memory usage exceeds configurable thresholds for extended periods
• Detects and reports swap memory usage
• Monitors for OOM (Out Of Memory) kill events
• Logs all events to a log file for later analysis

Requirements

• Python 3.6+
• psutil library

Installation

1. Clone this repository or download the script:

git clone https://github.com/asrul10/simple-memory-monitor.git
cd simple-memory-monitor

2. Install the required dependencies:

pip install psutil

Usage

Run the script with Python:

python main.py

The script will start monitoring your system memory and provide alerts when:

• Memory usage exceeds 80% for 2 minutes or more
• Any swap memory is being used
• OOM kill events are detected

All alerts are displayed in the console and also logged to memory_monitor.log.

Configuration

You can modify the following variables in the main() function to adjust monitoring thresholds:

• high_memory_threshold: Percentage of memory usage that triggers an alert (default: 80%)
• high_memory_min_duration: Minimum duration in seconds that memory must remain high to trigger an alert (default: 120 seconds)

Log File

The script creates a log file named memory_monitor.log in the same directory. This file contains all monitoring events with timestamps.
