      Monitoring

      TKE currently provides monitoring metrics of the following dimensions. All metrics are average values within the granularity.

      Monitoring Metrics for Clusters

      Monitoring Metric Unit Description
      CPU Utilization % CPU utilization rate of entire cluster
      MEM Utilization % Memory utilization rate of entire cluster

      Monitoring Metrics for Master & Etcd and Ordinary Nodes

      Monitoring Metric Unit Description
      Re-startup of Pods restarts Sum of the number of restarts of all pods on the node
      Exception - Node status: normal or exceptional
      CPU Utilization % CPU usage of all pods on the node to the total CPU of the node
      MEM Utilization % Memory usage of all pods on the node to the total memory of the node
      Private bandwidth in bps Total private network inbound bandwidth of all pods on the node
      Private bandwidth out bps Total for private network outbound bandwidth of all pods on the node
      Public bandwidth in bps Total public network inbound bandwidth of all pods on the node
      Public bandwidth out bps Total public network outbound bandwidth of all pods on the node
      TCP Connections Count connections Number of TCP connections maintained on the node

      For more information on monitoring metrics for cluster nodes, please see Get Monitoring Statistics.

      For more information on monitoring metrics for cluster node data disks, please see Monitoring Cloud Disks.

      Monitoring Metrics for Workloads

      Monitoring Metric Unit Description
      Re-startup of Pods restarts Total for the number of restarts of all pods in the workload
      CPU Usage cores CPU usage of all pods in the workload
      CPU Utilization (% cluster) % CPU usage of all pods in the workload to the total CPU of the cluster
      MEM Usage B Memory usage of all pods in the workload
      MEM Utilization (% cluster) % Memory usage of all pods in the workload to the total memory of the cluster
      Network Inbound Bandwidth bps Total inbound bandwidth of all pods in the workload
      Network Outbound Bandwidth bps Total for outbound bandwidth of all pods in the workload
      Network Inbound Traffic B Total inbound traffic of all pods in the workload
      Network Traffic Out B Total outbound traffic of all pods in the workload
      Network Inbound Traffic packets/sec Total inbound packets of all pods in the workload

      If the workload provides services outside the cluster, please see Obtaining Monitoring Data for more information on network monitoring metrics for bound services.

      Alarms

      TKE currently provides alarm metrics of the following dimensions. All metrics are average values within the statistical period.

      Alarm Metrics for Clusters

      Monitoring Metric Unit Description
      CPU Utilization % CPU utilization rate of entire cluster
      MEM Utilization % Memory utilization rate of entire cluster

      MEM Allocation % Ratio of the sum of the set Requests from all containers in the cluster to the cluster’s total allocable memory resources
      Apiserver Normal - Apiserver status. By default, alarms when status value is False. Only self-deployed clusters support this metric.
      Etcd Normal - Etcd status. By default, alarms when status value is False. Only self-deployed clusters support this metric.
      Scheduler Normal - Scheduler status. By default, alarms when status value is False. Only self-deployed clusters support this metric.
      Control Manager Normal - Control Manager status. By default, alarms when status value is False. Only self-deployed clusters support this metric.

      Alarm Metrics for Nodes

      Monitoring Metric Unit Description
