Disable

Disable Infrastructure Monitoring (Infra)

By default, UniAgent will enable infrastructure monitoring for all Nodes in the cluster.

To disable infrastructure monitoring for a specific Node, set the label: tingyun-infra-monitor=disabled.

kubectl label node [Node name] tingyun-infra-monitor=disabled

Disable Application Monitoring (APM)

• To disable monitoring for a specific deployment/daemonset/statefulset/pod, annotate the label tingyun-agent-injected: "true" in the yaml, and redeploy the application that has already been injected.

• To disable monitoring for all applications under a Namespace, set the Namespace label: tingyun-injection=disabled, and redeploy the applications that have already been injected.

  kubectl label namespace [namespace of the application] tingyun-injection=disabled

• To disable monitoring for all applications in the entire Kubernetes cluster, set the global configuration switch of UniAgent to apm_enabled: false, and redeploy the applications that have already been injected.

  After modifying the configuration, it will take effect dynamically, but there will be a certain delay. The delay time depends on the kubelet startup parameter --sync-frequency, which defaults to 1 minute. Therefore, after updating the contents of the ConfigMap, you need to wait about 2 minutes.

  • Recommended method: Modify the yaml file used for Agent installation.

    Set apm_enabled in tingyun-common-config in tingyunagent.yaml to false.

    # Global configuration, required
    # configmap
    # tingyun-common
    
    apiVersion: v1
    kind: ConfigMap
    metadata:
      name: tingyun-common-config
      namespace: tingyun
    data:
      tingyun-common.yaml: |
        infra_dc: http://10.128.2.95:11001
        apm_dc: http://10.128.2.95:7071
        apm_enabled: true
        apm_aggressive: false

    Then update using the yaml file.

    kubectl apply -f tingyunagent.yaml

  • Command method: If the yaml file used for installation has been lost, use the following command.

    kubectl edit configmap tingyun-common-config -n tingyun

    You will see an interface similar to the following. Set apm_enabled in tingyun-common.yaml to false, save and exit.

    apiVersion: v1
    data:
      tingyun-common.yaml: |
        infra_dc: http://10.128.2.95:11001
        apm_dc: http://10.128.2.95:7071
        apm_enabled: true
        apm_aggressive: false
