kube-controller-manager输出metrics问题

[Simon-special]

文档版本 K8s V1.18 说明你查看的是哪个 branch 的文档，即 K8S 版本，如 v1.8、v1.12。

现象描述 部署完成kube-controller-manager后在获取metrics时取到的值是

HELP apiserver_audit_event_total [ALPHA] Counter of audit events generated and sent to the audit backend.

TYPE apiserver_audit_event_total counter

apiserver_audit_event_total 0

HELP apiserver_audit_requests_rejected_total [ALPHA] Counter of apiserver requests rejected due to an error in audit logging backend.

TYPE apiserver_audit_requests_rejected_total counter

apiserver_audit_requests_rejected_total 0

HELP apiserver_client_certificate_expiration_seconds [ALPHA] Distribution of the remaining lifetime on the certificate used to authenticate a request.

TYPE apiserver_client_certificate_expiration_seconds histogram

apiserver_client_certificate_expiration_seconds_bucket{le="0"} 0 apiserver_client_certificate_expiration_seconds_bucket{le="1800"} 0

但是文档中的值是 curl -s --cacert /opt/k8s/work/ca.pem --cert /opt/k8s/work/admin.pem --key /opt/k8s/work/admin-key.pem https://172.27.138.251:10252/metrics |head

HELP ClusterRoleAggregator_adds (Deprecated) Total number of adds handled by workqueue: ClusterRoleAggregator

TYPE ClusterRoleAggregator_adds counter

ClusterRoleAggregator_adds 3

HELP ClusterRoleAggregator_depth (Deprecated) Current depth of workqueue: ClusterRoleAggregator

TYPE ClusterRoleAggregator_depth gauge

ClusterRoleAggregator_depth 0

HELP ClusterRoleAggregator_longest_running_processor_microseconds (Deprecated) How many microseconds has the longest running processor for ClusterRoleAggregator been running.

TYPE ClusterRoleAggregator_longest_running_processor_microseconds gauge

ClusterRoleAggregator_longest_running_processor_microseconds 0

HELP ClusterRoleAggregator_queue_latency (Deprecated) How long an item stays in workqueueClusterRoleAggregator before being requested.

请问这俩个值都是正常的嘛，如果都是正常的分别代表什么意思呢，还请大神指点一二
