func GetMetrics

func GetMetrics() *PrometheusMetrics

func (*PrometheusMetrics) DeleteClass

func (pm *PrometheusMetrics) DeleteClass(className string) error

DeleteClass deletes all metrics that match the class name, but do not have a shard-specific label. See [DeleteShard] for more information.

func (*PrometheusMetrics) DeleteShard

func (pm *PrometheusMetrics) DeleteShard(className, shardName string) error

Delete Shard deletes existing label combinations that match both the shard and class name. If a metric is not collected at the shard level it is unaffected. This is to make sure that deleting a single shard (e.g. multi-tenancy) does not affect metrics for existing shards.

In addition, there are some metrics that we explicitly keep, such as vector_dimensions_sum as they can be used in billing decisions.
