Description

i believe this is a bug
offline partitions is a metric that indicates an error condition - lack of kafka availability.
as an artifact of how deletion is implemented the partitions for a topic undergoing deletion will show up as offline, which just creates false-positive alerts.

if needed, maybe there should exist a separate "partitions to be deleted" sensor.
