Is your feature request related to a problem? Please describe.
Cortex provides a MaxLabelsSizeBytes
limit for the max combined size in bytes of all labels and label values for a given metric name, but does not emit the metric this is compared to. Exposing such a metric would help users to know how close they are to hitting the limit in case they intend to add more labels to a metric name.
Describe the solution you'd like
Expose the labelSizeBytes
as a native histogram metric that tenants can monitor.
