    Before you begin

    Role required: discovery_admin.

    About this task

    If you use a ServiceNow DaemonSet, a pod is running on each Kubernetes node and reports to the main Informer pod every 60 seconds on new connections detected. For more information, see Install Kubernetes Visibility Agent (KVA)

    Procedure

    Set parameters either during Helm chart archive installation or by modifying the Kubernetes YAML file provided by ServiceNow.
