    TKE Serverless Cluster collects and displays metrics for clusters, workloads, pods, and containers.

    Prerequisites

    An TKE Serverless cluster has been created and is in the Running state. For more information, see Creating a Cluster.

    Procedure

    1. Log in to the TKE console and click Elastic Cluster in the left sidebar.
    2. On the Cluster Management page that appears, click the ID of the TKE Serverless cluster.
    3. On the cluster resource management page, view the metrics and configure alarms for them. For more information, see the following documents:

    Monitoring and Alarm Metrics

    Monitoring metrics

    TKE currently provides monitoring metrics in the following dimensions. All metrics are average values of the statistics collected within the statistical period.

    Note:

    Monitoring metrics for a cluster

    Metric Unit Description
    CPU Usage Core Total number of CPU cores used by the running pods in the cluster
    MEM Usage B Total amount of memory used by the running pods in the cluster

    Monitoring metrics for a workload

    Metric Unit Description
    Restart of Pods Times Total number of times the pods in the workload are restarted
    CPU Usage Core Total number of CPU cores used by the pods in the workload
    CPU Utilization (% of Pod Specification) % Percentage of the CPU cores allocated to the pods in the workload that is used by the pods
    MEM Usage B Total amount of memory used by the running pods in the workload
    MEM Utilization (% of Pod Specification) % Percentage of the memory capacity allocated to the pods in the workload that is used by the pods

    Monitoring metrics for a pod

    Metric Unit Description
    Exception - Status of the pod, which can be normal or abnormal
    CPU Usage Core Number of CPU cores used by the pod
    CPU Utilization (% of Request) % Percentage of the total number of CPU cores specified by Request that is used by the pod
    CPU Utilization (% of Limit) % Percentage of the total number of CPU cores specified by Limit that is used by the pod
    CPU Utilization (% of Pod Specification) % Percentage of the CPU cores allocated to the pod that is used by the pod
    MEM Usage B Amount of memory used by the pod, including the cache usage for the pod
    MEM Utilization (% of Request) % Percentage of the total amount of memory specified by Request that is used by the pod
    MEM Utilization (% of Limit) % Percentage of the total amount of memory specified by Limit that is used by the pod
    MEM Utilization (% of Pod Specification) % Percentage of the memory capacity allocated to the pod that is used by the pod

    Monitoring metrics for a container

    Metric Unit Description
    CPU Usage Core Number of CPU cores used by the container
    CPU Utilization (% of Request) % Percentage of the total number of CPU cores specified by Request that is used by the container
    CPU Utilization (% of Limit) % Percentage of the total number of CPU cores specified by Limit that is used by the container
    MEM Usage B Amount of memory used by the container, including the cache usage for the container
    MEM Utilization (% of Request) % Percentage of the total amount of memory specified by Request that is used by the container
    MEM Utilization (% of Limit) % Percentage of the total amount of memory specified by Limit that is used by the container

    Alarm Metrics

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

    Alarm metrics for a pod

    Metric Unit Description
    CPU Utilization (% of Pod Specification) % Percentage of the CPU cores allocated to the pod that is used by the pod
    MEM Utilization (% of Pod Specification) % Percentage of the memory capacity allocated to the pod that is used by the pod
    CPU Utilization (% of Request) % Percentage of the total number of CPU cores specified by Request that is used by the pod
    MEM Utilization (% of Request) % Percentage of the total amount of memory specified by Request that is used by the pod
    CPU Utilization (% of Limit) % Percentage of the total number of CPU cores specified by Limit that is used by the pod
    MEM Utilization (% of Limit) % Percentage of the total amount of memory specified by Limit that is used by the pod
    Restart of Pods Times Number of times the pod is restarted.
    Pod Ready - Status of the pod. By default, an alarm is generated when the value is False.
    CPU Usage Core Number of CPU cores used by the pod
    MEM Usage MB Amount of memory used by the pod, including the cache usage for the pod
