NETSCOUT nGeniusONE Review

For service assurance, in SMS in particular, they use it very heavily to proactively hit issues

What is our primary use case?

We used to use it for application debugging, in particular SMS and MMS, but lately, we've been turning towards using it for OpenStack and cloud-issue debugging.

How has it helped my organization?

In a network deployment, it provides us with increased visibility.

From the service assurance perspective, in SMS in particular, they use it very heavily to proactively try to hit issues. There are a lot of times where NETSCOUT will catch something spinning up the SA organization and then, in turn, spinning up the operations organization to go catch and kill it; or it comes over to network development. So it's used fairly extensively.

We use it on the cloud side more from a reactive perspective and it's certainly helped us catch and kill a couple of issues that we wouldn't have been able to otherwise. 

It helps us get to root cause quickly. We had an OpenStack Cinder issue, a storage-type issue, and we chased our tails on that for quite some time until we managed to get the data over to a NETSCOUT probe. Then we were able to very rapidly figure out what the heck was going on.

When we can get the data into the tool, we absolutely see a decrease in mean time to know and mean time to repair, and similarly for overall troubleshooting time. With that Cinder issue, we spun our wheels for almost two weeks before we managed to get the data over to the tool and, once we did, we solved it fast. So it can be days or weeks of saved time.

In terms of application uptime, it's deployed and leveraged for almost all the applications in our organization: VoLTE, SMS, MMS, etc. So as heavily as the service assurance groups and operations use it, I'd say that they consider it pretty essential at this point.

What is most valuable?

Among the valuable features, if it's TAP'ed well, are the density of the data that you can get and the relatively high veracity or accuracy rate that we see from it.

What needs improvement?

In terms of additional features, Bruce Kelly was talking about the NFV and 5G aspects of it, in monitoring all the APIs for all of those functions. We're really looking forward to seeing that so that we can give better visibility into the functioning of the cloud and the orchestrator itself.

There is room for improvement in its stability and by expanding into the cloud and orchestration sphere, which I think is on the roadmap.

What do I think about the stability of the solution?

The stability is only fair. It goes down a lot.

What do I think about the scalability of the solution?

It scales out fairly widely, horizontally. And with the new virtual one, we'll be doing it a lot wider. So it has good scalability.

How are customer service and technical support?

Technical support is good. We've got good onsite support and those guys are generally available.

Which solution did I use previously and why did I switch?

We knew we needed to invest in a new solution because we couldn't fix things.

What was our ROI?

We see ROI through the ability to fix and to keep the perception that our network is up 100 percent. That is absolutely critical. It keeps the customers coming in.

Which other solutions did I evaluate?

We also looked at Empirix.

What other advice do I have?

Consider what your applications are for this and purchase your features accordingly.

Regarding the single pane of glass view, we don't think we've really fully deployed it from a cloud perspective, but from a VoLTE perspective, I know they're starting to get on top of it. From an SMS perspective, we found it very useful.

I'll give it an eight out of ten as it stands today. It's very useful, but we do see some stability concerns. There is a lot of maintenance around the probes, and I think there needs to be more development done in the cloud sphere.
