Monitoring Tenant Details
This topic describes how to monitor details about the tenants that are part of your overlay network. You can create overlay networks and tenants in Network Director by using Layer 3 Fabrics that are created and managed from Network Director. You can monitor the tenant details for the entire network, for a specific Layer 3 Fabric that acts as the underlay for the tenant overlay network, or for a data center that uses a Layer 3 Fabric.
To view the tenant details:
- Click Monitor in the Network Director banner.
- Select the Summary tab.
- For the Monitor life cycle mode, select a combination
of view and a device or container as shown in Table 1.

From the Tasks pane, select Tasks > View > View Tenants.
The View Tenants window opens, displaying a list of tenants.
The View Tenant task is enabled for devices that are at the virtual chassis level.
You can use the filters available on this window to sort ports by Port Utilization percentage or Port Status.
Use the breadcrumbs at the top of the window to navigate to the various views within the View Tenant window. For example, in Figure 1, from the Endpoint view, you can click All Ports to view details of all the ports that Tenant 1 uses, click Tenant 1 to view the port details summary for Tenant 1, or click All Tenants to view the details of all the tenants in the View Tenants window.
You can perform the following tasks from the View Tenants window:
Viewing the List of Tenants
The View Tenants window enables you to view details about the tenants, the number of ports used by a tenant, and the status of the ports. The level of information that Network Director displays in this window depends on the scope that you select. If you select a Layer 3 Fabric, this window displays the tenants that are part of that fabric, whereas if you select from My Network, this window displays all the tenants that are part of the network—tenants from multiple data centers and fabrics.
The View Tenant details table displays the details of all the tenants and their port status and utilization. See Table 2 for a description of the fields in this table.
Table 2: View Tenant Details Table Field Descriptions
Name of the tenant.
VXLAN ID of the overlay networks for the tenant.
Number of ports that the tenant uses.
Number of Ports with Status
Displays the number of ports that are up and ports that are down in separate columns.
Ports with Utilization (%)
Displays the number of ports that utilize high, medium, and low bandwidth in separate columns.
View Port Details of Tenants
To view more details about the ports that are used by a tenant:
- In the View Tenants window, click the number of ports
field corresponding to a tenant for which you want to view more details.
The Port Details view opens.
Table 3 describes the fields of the Port Details view.
You can click the number of ports in any of fields—Total Ports, Number of Ports with Status, or Ports with Utilization (%)—to open the Ports Details view. Network Director filters the ports based on the column that you clicked. For example, if you click the port number in the Total Ports column, the Port Details window displays all the ports that the tenant uses; If you click the port number in the Ports with Utilization (%) > High, the Port Details view filters and displays only the ports that have high utilization.
Table 3: Port Details View Field Descriptions
The device on which the given port exists.
The port number.
Indicates whether the port is up or down.
Port Utilization %
Utilization (percentage) of the selected port.
Click to view details about the VXLAN endpoints.
The View All Endpoints window opens.
Endpoints are the hosts on which a tenant network terminates. You can view the endpoint details for each VXLAN overlay network.
To view endpoint details:
From the Port Details view, click Show Endpoints in the Actions column to view the end point details for a tenant on a specific device and port. The Show Endpoints window opens displaying the port number and the corresponding MAC address on a host.
View the Port Utilization Trend for a VXLAN Port
To view the port utilization trend for a port:
- From the Port Details view, click in the Port Utilization % column to view the
utilization trend for the port.
The Port Utilization Trend window is divided into three sections—packets details graph, port details, packet counter and error count table.
The packet details graph displays the number of packets that passed through the port per second plotted during a certain time period as shown in Figure 2. The vertical axis on the left shows the number of packets per second. The horizontal axis shows the time when the packet count was taken. The dotted lines indicate the number of errors. You can read the error count for any time period by using the vertical axis on the right.
The default polling interval for the packet details graph is 1 hour. You can modify this by selecting an appropriate value from the polling interval drop down list that is displayed above the packet details graph.
The port details section displays the port name, port usage, MAC address of the port, and the number of packets that passed through the port.
The packet counter and error count table consists of two sub-tabs. The Packet Counter sub-tab displays the distribution of unicast, broadcast, and multicast traffic types on the port you selected. The port traffic is classified as Unicast In, Broadcast In, Multicast In, Unicast Out, Broadcast Out, and Multicast Out.
The Error Count sub-tab displays the count of packet errors under each major error category.
You can select or clear each counter to view or hide details about a specific counter in the packet details graph.
