would this record as many NodePools as we have in a platform? e.g in a management cluster with 80 HC and 3 NodePools each that would be 240 time series.
Do we know what's our cardinality budget for telemetry? cc @csrwng

[muraee]

right, other alternative is to use sum by (platform) which would yield the total number of nodes across all clusters/nodepools, but I am not sure if that would be useful.
