envhealth 1.0.0

Environment health checker that validates Python runtime, OS, dependencies, variables and system readiness

envhealth

EnvHealth is a powerful Python utility to check system environment health.

Features

• Operating System details
• CPU usage and core stats
• RAM usage
• Disk usage
• CUDA GPU availability + performance benchmark
• Internet connection diagnostics
• Proxy configuration detection
• Package version drift detection (major / minor / patch)
• Deprecated & insecure package flags
• CI-friendly exit codes

Supports multiple report formats:

• Pretty terminal output (Default)
• JSON

---

Installation

You can install envhealth via pip:

pip install envhealth

After installation, the CLI command will be available as:

envhealth

Usage

CLI Usage

• Run the environment checker in the console:

      envhealth
  

• Generate HTML, JSON, or Markdown reports:

      envhealth --html
      envhealth --json
      envhealth --pdf
  

• Save reports to a custom path:

  envhealth --json --path /custom/output/dir
  envhealth --html --path C:\reports
  envhealth --pdf --path ./reports
  

• CI / automation usage:

  envhealth --fail-on minor
  envhealth --fail-on major
  

  • Exit codes:
    • 0 → No failure
    • 1 → Minor version drift
    • 2 → Major version drift

CLI Flags Reference

Flag	Description
--json	Save report as JSON
--html	Save report as HTML
--pdf	Save report as PDF
--path	Custom directory to save reports
--fail-on minor	Exit with code 1 if minor drift detected
--fail-on major	Exit with code 2 if major drift detected
--help	Show all CLI options

Default Save Location

If bash --json, bash --html, or bash --pdf is used without bash --path, the report is saved to:

• Windows → Desktop
• macOS → Desktop
• Linux → Desktop (fallback: home directory) Each run prints the exact saved file path.

Programatic Usage

• Use envhealth in your Python scripts:

  from envhealth import Checker, Reporter
  
  checker = Checker()
  data = checker.full_report()
  
  reporter = Reporter(data)
  
  print(reporter.pretty_text())
  
  # Save reports
  reporter.save_json()
  reporter.save_html()
  reporter.save_pdf()
  

You may also pass a custom path:

    from pathlib import Path

    reporter.save_json(Path("./reports"))

PDF Output

Saved as bash envhealth_report.pdf Generated using reportlab, suitable for audits and sharing.

CI Failure – JSON Example

When bash envhealth is used in CI mode with bash --fail-on, it still produces a valid JSON report, but the process exits with a non-zero code. Command:

    envhealth --json --fail-on major

Condition	Exit Code
No drift	0
Minor drift	1
Major drift	2

This allows GitHub Actions, GitLab CI, Jenkins, etc. to fail the pipeline.

--help Command

EnvHealth provides a built-in help command using Python’s standard CLI interface.

To view all available commands and options:

    envhealth --help

The help output includes:

• A short description of the tool
• All supported CLI flags
• Accepted values for each flag
• Usage examples

Example

    usage: envhealth [-h] [--json] [--html] [--pdf] [--path PATH]
                 [--fail-on {minor,major}]

    Environment Health Checker

    options:
    -h, --help            show this help message and exit
    --json                Save report as JSON
    --html                Save report as HTML
    --pdf                 Save report as PDF
    --path PATH           Directory to save generated reports
    --fail-on {minor,major}
                            Fail CI if version drift reaches this level

[!NOTE]

• --help is available on all platforms (Windows, Linux, macOS)
• It is automatically provided and always up-to-date with the CLI
