[rafaelameijeiras]

Summary

Adds the documentation page for the Network bandwidth SNMP plugin, in English and Spanish.

Type of change

• New page
• New section / subcategory
• Edit to an existing page
• Image(s) only
• Repository/tooling change (workflows, config, template, ...)

Details

• Section affected: Plugins
• Languages:
  • English (docs/en/)
  • Spanish (docs/es/)
• Sidebar impact: none (no changes to mkdocs.yml or hooks.py)
• Files changed:
  • docs/en/plugins/snmp-bandwidth.md — new Network bandwidth SNMP plugin page
  • docs/es/plugins/snmp-bandwidth.md — Spanish version of the same page

Verification

• Validator tests pass: python3 -m unittest discover -s tests -p 'test_validate_docs.py'
• Blocking quality gates pass: python3 scripts/validate_docs.py --fail-on blocking (0 blocking findings)
• Strict build completed successfully (check one command): not run — .venv is not present locally and the docker compose run failed inside the container entrypoint (permission error), so this is left to CI/reviewer
  • .venv/bin/mkdocs build --strict
  • UID=$(id -u) GID=$(id -g) docker compose run --rm docs build --strict
• Images referenced with correct relative path and per-language fallback (n/a: the pages reference no images)
• Optional: preview checked at http://localhost:8000 (preview is not validation)
