Data Center Migration- Network Virtualization Use

Jump to solution

Hello Experts,

Our org is migrating the data center from NY to Location Calif ,but users will access the application from NY and our LG machines are also migrating to calif. In this case,can we use network Network Virtulization to monior the network packet loss or for latency?

If so, can you please suggest how to use NV during test?

1)We already purchased license for LR and not for NV. iF we have to purchase license for NV,on what basis should be purchased? Like number of users or location?

2)Should we install NV on both Controller and LG machines ?

Please advise.

Hi,

"Can we use Network Virtualization to monitor the network packet loss or for latency?"

There are several methods, depending on the type of application (for example, consumer facing or internal, mobile or desktop), for discovering with which network conditions an application should be tested.

In some cases you can use information your company already has, latency/loss between different sites from the Networking team for example, and in others measuring the latency/loss (site to DC for example) with continues ping may suffice.

With an NV license, you can also use the NV Global Library in LR which provides mobile network conditions of different connections (e.g. 3G/4G) in many locations (i.e cities), and landline network conditions between some locations. Or the NV Network Capture server/agents which allow you to measure/monitor the latency/loss between locations (site to DC for example), and then export the results to a file which can be imported in LR.

Hope it helps, let us know if you have further questions.

Hi

Let me try and answer your questions in order:

can we use network Network Virtulization to monior the network packet loss or for latency? - Yes, you can. once you install NV, you get the network monitoring graphs each time you run a test. you can read more in this documentation part.

with regards to your other questions, you should purchase an NV license based on the number of Vusers you wish to emulate (the NV license is for users, not locations). you can choose to emulate all your users, or emulate part and have a group of Vusers as your "Control group" to see how your application behaves with and without emulation.

NV is installed as part of the LoadRunner full installation, or it can be installed on the seperate components if you do a distribtued installation, in which case you should install the specific NV installation for the controller on the controller and the specific NV installation for the LG on the LG (both installations are in the "Additional components" folder on the installation DVD.

Good luck and feel free to ask any and all questions you have.

Thanks,

Lior

Thank you the suggestion.

In controller on NV, i have configured Virtual location as Newyrok to California and added the custom setting like Bandwidth and Latency.

Do i need to configure any other settings before running the test? Just adding the Virtual location can simulate the behavior as expecting(like client in Newyork and Severs in calif)?

 

Please advise
