  version: 10.20.0
  description: 'Raise, query, acknowledge, clear, and bulk-update alarms with four severity levels (CRITICAL, MAJOR,

    MINOR, WARNING) and four statuses (ACTIVE, ACKNOWLEDGED, CLEARED). Cumulocity auto-deduplicates alarms

    by source + type so repeated raises increment the count rather than creating duplicates.
