This section describes how to view the network topology diagram and the network traffic list.

Prerequisites

  • You need to have the platform-admin role on the KubeSphere platform. For more information, see Users and Platform Roles.

  • The WizTelemetry Network Observability extension must be installed and enabled on the KubeSphere platform.

Steps

  1. Log in to the KubeSphere web console with a user who has the platform-admin role.

  2. In the upper right corner of the page, click the grid icon and select WizTelemetry Observability Platform.

  3. Click Network > Network Topology in the left navigation pane.

  4. On the page, use the dropdown menus at the top to select the cluster, source project, and target project to view the network topology diagram and network traffic data between specific projects within a specific cluster.

    Parameter Description

    Source Project

    The project where the data sender is located, i.e., the starting point of the data flow.

    Target Project

    The project where the data receiver is located, i.e., the ending point of the data flow.

    • Click refresh in the upper right corner to refresh the page information.

    • Click clock-2 in the upper right corner to set the time range for the data. The default is Last 30 minutes.

  5. The Network Topology Diagram displays the resource type (pod, service, cluster node, or IP address), resource name, and total transmission rate for each topology node, as well as the interaction relationships between topology nodes. You can also perform the following operations to get more information.

    • Hover the mouse over a topology node to view the related nodes communicating with it and the direction of data flow.

    • Click a topology node to view its resource name, belonging project, send rate, and receive rate.

    • Hover the mouse over a topology connection line to view the topology nodes at both ends of the line, and use left-right-button to understand the direction of data flow.

    • Click a topology connection line or the left-right-button on it to view the start point, end point, and data transmission rate of that data flow segment.

    • Click topology_1 to view the topology diagram in the default view. In the default view, you can freely drag the topology nodes.

    • Click topology_2 to view the topology diagram in the arranged view. Topology nodes will be arranged in a certain direction for easier viewing.

    • Click zoom_in/zoom_out to zoom in or zoom out the topology diagram.

    • Click maximize to view the topology diagram in full screen.

  6. In the Network Traffic area, view the network traffic data for the selected project within the specified time range.

    Click caret-down on the right side of the table header to sort the list in ascending/descending order.

    Parameter Description

    Source End

    The network endpoint that initiates the communication request, displaying the resource type and resource name of this topology node.

    Target End

    The network endpoint that receives the communication request, displaying the resource type and resource name of this topology node.

    Send Rate

    The rate at which the source end transmits data to the target end.

    Receive Rate

    The rate at which the target end receives data from the source end.

    Total Rate

    The sum of the send rate and receive rate.

    TCP Drops

    The number of TCP packets dropped per second.

    A high drop rate may indicate network instability or device overload, requiring network configuration optimization or resource scaling.

    TCP Retransmissions

    The number of TCP packets retransmitted per second.

    Frequent retransmissions usually indicate network latency or packet loss, which may affect transmission efficiency. It is necessary to check for network latency or congestion.
