    Namespace = QCE/TKE2

    Monitoring Metrics

    Note:

    The following four metrics are not supported for managed clusters: K8sComponentApiserverReady, K8sComponentControllerManagerReady, K8sComponentEtcdReady, and K8sComponentSchedulerReady.

    Overview of Parameters in Each Dimension

    Parameter Name Type Dimension Name Description Format
    Conditions.N.Dimensions.N.Name Required tke_cluster_instance_id Dimension name of the cluster Enter a string-type dimension name, such as `tke_cluster_instance_id`
    Conditions.N.Dimensions.N.Value tke_cluster_instance_id Specific cluster ID Enter a specific cluster ID, such as cls-fvkxp123
    Conditions.N.Dimensions.N.Name workload_name Dimension name of the workload name Enter a string-type dimension name, such as `workload_name`
    Conditions.N.Dimensions.N.Value workload_name Specific workload name Enter a specific workload name, such as coredns
    Conditions.N.Dimensions.N.Name Optional (zero, one, or multiple of which can be passed in optionally) node Dimension name of the node name Enter a string-type dimension name, such as `node`
    Conditions.N.Dimensions.N.Value node Specific node name Enter a specific node name, such as node

    Conditions.N.Dimensions.N.Value un_instance_id Specific node ID Enter a specific node ID, such as ins-nwjhh123
    ## Statistical Granularity and Time Span

    The supported time span varies by statistical granularity. When pulling monitoring data, you should pay attention to the time span restrictions as detailed below:

    Statistical Granularity Maximum Time Span (End Time - Start Time)
    60s 12 hours
    300s 3 days
    3600s 30 days
    86400s 186 days

    Input Parameter Description

    In the cluster dimension, use the following input parameters:
    &Namespace=QCE/TKE2
    &Conditions.N.Dimensions.0.Name=tke_cluster_instance_id
    &Conditions.N.Dimensions.0.Value=cls-fvkxp123

    In the node ID dimension, use the following input parameters:
    &Namespace=QCE/TKE2
    &Conditions.N.Dimensions.0.Name=tke_cluster_instance_id
    &Conditions.N.Dimensions.0.Value=cls-fvkxp123
    &Conditions.N.Dimensions.1.Name=un_instance_id
    &Conditions.N.Dimensions.1.Value=ins-nwjhh123

    In the node name dimension, use the following input parameters:
    &Namespace=QCE/TKE2
    &Conditions.N.Dimensions.0.Name=tke_cluster_instance_id
    &Conditions.N.Dimensions.0.Value=cls-fvkxp123
    &Conditions.N.Dimensions.1.Name=node
    &Conditions.N.Dimensions.1.Value=node
