check_weather.py

Deterministic Weather Monitoring & Condition Validation

check_weather.py is a deterministic weather‑monitoring tool designed for NMS environments, automation pipelines, and operators who require reproducible, audit‑transparent condition checks.
It performs lightweight API requests, validates response integrity, normalizes weather conditions, and produces structured output suitable for monitoring systems.

Overview

check_weather.py provides a reproducible inspection pipeline for weather APIs.
It validates API availability, response structure, temperature ranges, condition codes, and precipitation indicators using deterministic logic consistent across environments.
The tool is built around three principles:

  1. Determinism — same conditions → same output
  2. Reproducibility — no environment‑dependent behavior
  3. Audit Transparency — explicit, structured, operator‑grade output

Key Features

  1. Deterministic weather API request handling
  2. Temperature, humidity, and wind validation
  3. Condition‑code normalization (clear, cloudy, rain, snow, etc.)
  4. Precipitation detection and severity classification
  5. Structured JSON and Nagios output modes
  6. API response integrity and schema validation

Architecture Overview

1. Request Layer

Performs a deterministic API request with strict timeout and explicit error classification.
Connection failures return UNKNOWN/CRITICAL states with clear diagnostic messages.

2. Response Parsing Layer

Extracts temperature, humidity, wind speed, condition codes, and precipitation indicators.
All fields are normalized for reproducibility.

3. Validation Layer

4. Output Layer

Produces deterministic JSON, verbose, or Nagios output.
All fields are explicit and audit‑transparent.

Why check_weather.py Exists

Traditional weather checkers often produce inconsistent output, rely on provider‑specific quirks, or provide limited visibility into condition codes and precipitation data.
check_weather.py solves this by applying deterministic engineering principles:

  1. explicit validation
  2. reproducible output
  3. audit‑transparent reporting
  4. no hidden behavior or implicit assumptions
It’s not just a weather checker — it’s a deterministic condition‑validation engine.
