About MAAS events

Errors or typos? Topics missing? Hard to read? Let us know.

Understanding MAAS events is crucial for debugging and verifying system functionality. These events represent changes in MAAS components like controllers, networks, or machines, triggered internally, by external factors, or through user actions such as machine commissioning.

Viewing events

  1. MAAS Logs: Offer raw, detailed data, accessible directly from the file system.
  2. UI Event Log: Provides a summarised view through a user-friendly interface.
  3. CLI events query Command: Quick, text-based overview of events.

Each source varies in detail and perspective. Here’s an example related to a node named “fun-zebra”.
