URLWatch

A Python monitoring script that continuously checks website availability based on entries from sites.txt.
Each line in the file follows the format: URL IMPORTANCE, where IMPORTANCE ∈ {INFO, WARNING, CRITICAL}.
Output uses colors: green for reachable sites, blue/yellow/red for unreachable INFO/WARNING/CRITICAL, and white for any other messages.

Phase 1 – File parsing and basic site checking

Implement a Python script that loads sites.txt, parses URL–IMPORTANCE pairs, and checks accessibility in a loop with colored status output.

• Parse file and validate entries
• Ping URLs periodically
• Display color-coded availability

Functional result: Script correctly reads inputs and shows live colored status for all sites.

Phase 2 – Filtering and configurable intervals

Add support for command-line options to filter by IMPORTANCE level and set the check interval, applying both to the continuous monitoring loop.

• Add CLI arguments for interval
• Add CLI filtering by IMPORTANCE
• Apply settings to monitoring logic

Functional result: Script monitors only selected categories at the chosen interval.
