Aggregate and free-space monitoring did not work on NetApp ASA r2 systems.
These systems use Storage Availability Zones instead of classic aggregates and do not accept the "uuid" field on the REST API CLI passthrough (/api/private/cli/aggr) that Checkmk uses to enumerate all aggregates including root aggregates (see Werk #18010). On ASA r2 that request returned no records, so no aggregate services were discovered at all.
Checkmk now additionally enumerates aggregates through the standard /api/storage/aggregates endpoint and combines the result with the CLI passthrough. On ASA r2 this discovers the data aggregates, which hold the relevant capacity. On classic ONTAP systems the behaviour is unchanged, since the CLI passthrough already returns a superset of those aggregates.
A re-discovery is required to start monitoring the affected aggregates.
