    • The first panel shows the number of open ports that were detected on each virtual network interface card (VNIC) in this Compute instance.

      A VNIC (virtual network interface card)  enables an instance to connect to a specific VCN (virtual cloud network) . To view details about a VNIC, hover your cursor over the chart.

    • The second panel shows the specific port numbers that were detected in this Compute instance.
  7. (Optional) Select one or more VNIC(s) to show only those ports that were detected on the selected VNICs.
