Version-Release number of selected component (if applicable): 4.8 Additional info: This can be verified by a before and after query: count({metrics_path="/metrics/cadvisor"}) --- Additional comment from Junqi Zhao on 2021-08-30 08:49:53 UTC --- tested with 4.9.0-0.nightly-2021-08-29-010334 with the fix, the count of the cadvisor metrics is less than that without the fix count({metrics_path="/metrics/cadvisor"}) {} 46166 without the fix count({metrics_path="/metrics/cadvisor"}) {} 56388
