What is our primary use case?
This solution has been implemented at banks and retailers to focus on network-based application performance management.
Aligning the solution with a visibility layer (taps, aggregation taps, and packet brokers - Ixia and Cubro), NMs system (Sintrex) we were able to deliver information relating to various applications and their behaviour.
Creating an environment where you triage a problem quickly and provide valuable information allows for improved MTTR.
This allows for a cross-silo approach, enhanced visibility, which enhances IT to better service the business.
How has it helped my organization?
We have partnered with Netscout over many years with various solutions - TruView, nGeniusOne, Infinistream, XG, etc.
With the focus on customer-defined applications and triggers we have been able to provide important information to clients regarding their application performance.
It has played an integral part in providing valuable information in a critical arena.
The ability to use pre-defined applications and configure client-specific applications allows for a comprehensive solution that enables all teams within the IT organization.
What is most valuable?
The combination of triggers with the ability to generate alarms.
The ability of the dashboards is useful for discover, mapping and understanding of application behaviour.
The ability to define client-specific applications.
If required, you can view up to a millisecond of what the behavior of the application is.
The ability to give insight into assigning the problem, with relevant information, to the correct team.
Detailed reporting that can be built with various perspectives and metrics.
Various dashboards can be built to service various applications or security teams.
What needs improvement?
The initial deployment is tedious and requires a lot of build, deployment and configuration time. Experience is key to a successful deployment.
It is critical to work with the network team to understand how the data flows across the estate to ensure that you tap, aggregate, de-capsulate, de-crypt, and de-duplicate correctly.
From these points, you need to ensure that the logical strategy and configuration suits the correct reporting and visibility as to ensure that you get the most out of any potential logical context.
It is also important to ensure that you spend time to understand the applications you want to profile and work with the application owners to ensure that everything is aligned correctly.
For how long have I used the solution?
We have been using this solution at multiple clients for many years.
What do I think about the stability of the solution?
In general, the stability is good, but we have had one or two incidents where specialized support was required.
What do I think about the scalability of the solution?
The solution can scale in most directions, bandwidth, hardware, virtual taps, etc.
How are customer service and technical support?
We have a good relationship with the vendor. They are always willing to help, but due to the complexity of the environment solving problems can take some time.
Which solution did I use previously and why did I switch?
We have previously made use of nMetrics, Spyke and older versions of the Netscout product range and still make use of ExtraHop Reveal (x).
We do however try to fit the need of the customer to the best solution and the vendor they prefer.
How was the initial setup?
Initial setup and configuration is complex and tedious and requires a methodical approach with experienced engineers.
What about the implementation team?
For complex implementations, we rely on the vendor for more support.
What was our ROI?
The return on investment is directly linked to the deployment, configuration, and management of the solution.
If you make it a priority, you will experience good ROI.
What's my experience with pricing, setup cost, and licensing?
It is important to spread the cost across the various IT silos as this solution works as an umbrella to provide information to all teams.
Try to target major aggregation points in your network to deliver the best potential data to the solution. You can from that point start to target specific areas to resolve specific issues or gain particular insight into certain areas.
Do not forget applications traverse North-South as well as East-West and in layers of those. Think about your typical WAN breakout, Layer 2 connections, Virtualized environments, and servers supported by back-to-back connections (eg. web server supported by DB server, with a direct connection).
Which other solutions did I evaluate?
Sintrex Flow Module, ExtraHop Reveal (x) - the reason we went with nGeniusOne was because the client has that they require a specific solutiion that NetScout answers, already deployed other Netscout solutions or that they had a specific function in mind (eg. InfiniStream tagging)
What other advice do I have?
It is always important to understand the problems you are trying to solve, what insight you are trying to gain and that this is a solution for the business, not just a specific IT silo or team.
Which deployment model are you using for this solution?
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
