Azure VM Issue Fixing

1. Optimize Application and Server Configuration

• Set Up Automatic Restart for Your Application: You can create a simple script to check if your application is running and restart it if it isn't. Use cron for periodic checks.

• Step 1: Identify the Main Python File

  1. Locate Your Python Application File:

     • Determine which Python file is the entry point for your application. Common names include:

       • app.py

       • main.py

       • Any specific filename your application uses.

  2. Navigate to Your Application Directory:

     • Use the terminal to go to the directory where your Python files are stored. For example:

       bashCopy codecd /home/soundarya/my_app  # Replace with your actual application directory

  3. List the Files:

     • Check which Python files you have by running:

       bashCopy codels *.py

  Step 2: Update the Check Script

  Once you've identified the main Python file, you can create a check script similar to the following example. Assume your main file is named app.py:

  1. Create or Edit the Check Script:

     • Open your check script (or create a new one) with your preferred text editor:

       bashCopy codenano check_app.sh

  2. Update the Script:

     • Use the following template, replacing app.py with the actual name of your Python file:

     bashCopy code#!/bin/bash
     
     # Check if the Python application is running
     if ! pgrep -f "python /home/soundarya/my_app/app.py" > /dev/null; then
         echo "Application not running, starting it..."
         nohup python /home/soundarya/my_app/app.py &  # Update with your actual app path
     fi

  Step 3: Make the Script Executable

  1. Change Permissions:

     • Make sure your script is executable:

       bashCopy codechmod +x check_app.sh

  Step 4: Set Up a Cron Job

  1. Schedule the Script:

     • Open your crontab configuration:

       bashCopy codecrontab -e

     • Add the following line to run the script every 5 minutes:

       bashCopy code*/5 * * * * /home/soundarya/check_app.sh  # Replace with your actual script path

  2. Save and Exit:

     • Save your changes and exit the editor.

  2.Scheduled Maintenance

  • Regularly Restart Your Applications: Use cron to schedule a regular restart of your applications during low traffic hours. This can help clear any memory leaks.

  Example Cron Job:

  bashCopy code0 2 * * * /path/to/restart_app.sh  # Restart at 2 AM every day
