An event clearinghouse engine is used with a data storage system to modify event disposition associated with components. A separate component disposition table is provided for each component. The component disposition table specifies different sets of disposition modifications for different types of events as indicated by event ID. A global disposition rule mapping table includes disposition modifications which are applied to all events. Per-vendor and per-tenant tables may be used to specify disposition modifications for particular vendors and tenants. Mode-specific tables such as a rescue/recovery mode table may be used to specify disposition modifications when the storage system is in a particular mode. The tables may be implemented in stages, including parallel and serial application.
