Network Virtualization statistics counters are not being displayed

When running a PC/LR load test with Network Virtualization, the NV statistical counters are not being displayed 

Please try these steps to resolve the issue.
1. Make sure that the times on all of the hosts are in sync.  It is recommended to use the same NTP Server to sync them
2. Make sure that the Controller and LG do NOT have the same hostname
3. Make sure that port 8182 are opened for all PC/LR hosts.
4. On the LG, start the Shunra NV Agent, chose the Active Adapter, and make sure that the adapter that is handling the test traffic is selected.
5. Make sure that the test scripts have the appropriate traffic (just ping test or think time do not count).

How to run Performance Center load-test with Professional mode WAN Emulation (user-defined *.NTX file located on a shared folder/drive)

The steps below will enable using a file from a shared folder/drive as the network characteristics for a Performance Center load-test when Professional mode WAN Emulation is enabled.

1. Access Performance Center user site and load the test settings to be updated (or create a new test)

2. Go to the Workload tab

3. Make sure Actual Load Generators are defined in the test

4. Click the WAN Emulation Settings… button (the button with the cloud image)

5. Select a load generator from the list

6. Mark the Enable WAN Emulation check-box

7. Click the WAN Emulation Settings button

8. Click the Additional Settings… button

9. Mark the Professional mode includes opening files located on a shared drive check-box

10. Click OK

11. Select the Professional radio-button

12. Click the Browse button and locate the NTX file to be used for that Load Generator

13. Click OK

Please note that the shared drive must be accessible to the Controller machines.

Shunra NV for HP LG component on the host with IP spoofing

How do I use the Shunra NV for HP LG component on the host with IP spoofing

On the LG with IP Spoofing, if the Active Adapter list does not have the IP address that is spoofed, then try this in CMD window.

vcatcli SetActiveAdapter -ip <IP Address> , where <IP Address> is the Address being spoofed.

If the LG Compoent is licensed (or still have the temporary 2-day license), then verify by:

1) Start a test with the NV Agent

2) Verify emulation by pinging the host’s Gateway

3) Start a test with HP LR or PC

4) Verify with the Shunra statistics graph and TRT of the tests

(NOTE: Ping test will not show emulation when starting test with HP LR or PC)
