User Flow:

• The user starts by running zerver.py with one of the following commands: start, stop, setup, or show.
• If the user chooses setup, they're prompted to enter a host name, which is then stored in MongoDB.
• If the user chooses start, the system runs as an admin and initiates various monitoring and logging processes.
• The user then waits while the system continuously monitors and logs data.

Execution Environment and Use Case:

• This system is designed to run on the server side, specifically on Windows servers running MySQL, Nginx, or both.
• It's a comprehensive monitoring and logging solution for server administrators. The practical use case is to provide real-time monitoring, security analysis, and performance tracking for web servers and databases.

• System uses several dependencies including pymongo, psutil, boto3, pandas, prophet, and others. It primarily focuses on:
  • Logging Nginx and MySQL activities - onto MongoDB
    • [format]: log_msg
  • Monitoring system resources (CPU, memory) & system Analysis
    • [using]: Wesng Windows assessment tool
  • Forecasting usage and costs
    • [how]: 1) stores access logs (2) Predict usage over next 100 days
  • Sending notifications for critical events
    • [using]: smtplib for threshold exceed/alert mailing
  • Store logs to AWS S3
