This table contains NVMF Namespace-level counters. These counters are available for every mapped namespace.

Classic Object: namespace

Table Row IDs

ID Format Aggregation Type Comment

{instance_name}:{instance_uuid}

(not applicable)

This represents the construction of the row ID field, which is a single unique string that identifies a row.

{node.name}:{instance_name}:{instance_uuid}

constituent

This represents the construction of a row ID field for a row from a single node.
