Events are stored in the Prometheus database and are deleted after 90 days. Bare Metal Orchestrator can store up to 150 Mb of events (or approximately 150,000 events). When the limit is reached, any new events overwrite the oldest events.
You can access all events using the Bare Metal Orchestrator web interface or download events using the CLI. You do not need to subscribe to an event as all events are automatically displayed. For more information about viewing events, see Bare Metal Orchestrator Web User Interface Guide and the Bare Metal Orchestrator API Guide.
