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. |
