Stanislav Laznicka b67bd722a9 rootcacertpublisher: drop the namespace label from metrics to reduce its cardinality ... The `root_ca_cert_publisher_sync_duration_seconds` metric tracks the sync duration in the root CA cert publisher per code and namespace. In clusters with a high namespace turnover (like CI clusters), this may cause the kube-controller-manager to expose over 100k series to Prometheus, which may cause degradation of that service. Drop the `namespace` label to remove the metrics' cardinality, tracking this metric by namespace does not justify the impact of keeping it.		2021-09-16 14:05:32 +02:00
