Monitoring VNFs Used in Network Services and the VMs That Host the VNFs

 

On the dashboard, the Network Service Overview provides information about the VNFs used in network services and the VMs that host those VNFs. You can also view information about the component VNFs in a network service by clicking Monitor Network Services in the left navigation bar.

To view information about VNFs used in network services and the VMs that host the VNFs:

  1. In the left navigation bar, click Dashboard.

    The dashboard appears, displaying several arrays of information.

  2. (Optional) In the Network Services Overview array, hover over a colored square in the array to see the latest event message for a specific parameter and host.
  3. (Optional) In the Network Services Overview array, click a colored square to see detailed information for a specific parameter and host.
  4. (Optional) In the Network Services Overview array, click an IP address to view all the event messages for a host.
  5. (Optional) In the Network Services Overview array, click a parameter name to view event messages on all hosts for that parameter.

See Table 1 for information about the monitoring parameters used for VNFs and the VMs that host them.
