Monitoring has improved bandwidth insights and application diagnosis but setup and costs still need work
They need room for improvement about the spare parts. There are shortages in Egypt in their stock. We tried to make RMA for specific parts, and it took a long time. Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time. This needs more improvement. I believe it is expensive. They need to reduce its budget a little bit. Comparing to other solutions, it is very expensive.

Very good for transaction level monitoring, but expensive and HP needs better support and training
HP Diagnostics is a very good monitoring tool especially for transaction level monitoring -- it shows hot spots which can be drilled down to DB level, table, query, SP's, record and field level and also at Object level, Classes level,method or Augment levels instead of pinpointing bottlenecks at layer level it goes deep inside for information. It has very good tracing capabilities despite being an agent based tool compared to other agent less monitoring tools. Overall a very good tool for monitoring application diagnostics for quick and easy resolution with help of thread information. Drills down from slow, end-user transactions to the bottle necked component, method, or SQL statement, helping to solve memory, exception, and other common problems Key features and benefits • Automatically detects all components touched by a business process and traces them with no user intervention • Provides complete application visibility across the application lifecycle, enabling higher application quality when applications go live • Reduces mean time to resolution (MTTR) in your J2EE, .NET, ERP, or CRM (SAP, Oracle®, PeopleSoft) environment • Integrates fully with HP Business Availability Center software, HP LoadRunner, and HP Performance Center.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We are attracting customers in good sized numbers as we advertise and market this solution."
"We use it for monitoring whenever we update a new circuit or site."
"The tool itself is just fantastic."
"These vendor interlocution situations have gone from a couple of weeks to a couple of days."
"The packet capture is the most valuable feature for us. It gathers data from the device. In case somebody has a problem, I can go back X amount of time - days, hours - and get the data to do real troubleshooting."
"We have seen a lot of return on investment: We have been able to recover radios in the field, we know exactly what is going on, we cut down fines from the service commission, and we have seen a measurable decrease in mean time to know, cutting troubleshooting down by days as we can now see the issues."
"The most valuable feature is visibility."
"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."
"The most valuable feature of Micro Focus Diagnostics is the information reported from an application that has timed out. For example, when you're Googling, or you're booking a ticket for Burj Khalifa here, the longest tower in the world, there are situations where the system can time out. There are times when you might not receive a response on the payment gateway or you are not able to find the reservation. The customer only receives the information that the session has timed out."
"HP Diagnostics is a very good monitoring tool especially for transaction level monitoring -- it shows hot spots which can be drilled down to DB level, table, query, SP's, record and field level and also at Object level, Classes level, method or Augment levels instead of pinpointing bottlenecks at layer level it goes deep inside for information."
"For banking and telecom solutions, it's been quite useful."
"The information from the diagnostics is detailed."
"The diagnostics and configuration are the solution's most valuable aspects."
 

Cons

"On a network the size of ours, the loading times seem a little extensive, 20 or 30 seconds to load up some graphs."
"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."
"There is currently less visibility or GUI to analyse the packet for troubleshooting purposes."
"The single pane of glass view is a challenge. I like the graphics, they're easy to understand, but when more digging is required, it's more complicated to get what I'm expecting."
"There are so many features that it makes it hard to know it all. You end up paying for things that you don't use and probably don't even need. It might be better if Netscout came up with a modular way to pay for what you're going to use and not pay for all of this "white elephant" without being able to take advantage of all of it."
"There are so many pieces of their product that integrate with one another that perhaps a recommendation for improvement would be some sort of bigger overview and map to help understand how all their pieces integrate together."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"A lot of tools highlight what's going on but they don't actually pinpoint the user experience. It would be good if there were a small message or something highlighting what the user experience is like and any degradation that's actually occurring."
"Price is little expensive for number of license points and HP Diagnostics trainers are not available in market and no proper support from HP for any diagnotics level queries or issues."
"The interface is very old, and not very user-friendly. Most of our clients don't like the UI."
"The interface could be more user friendly."
"The GUI and metrics of Micro Focus Diagnostics can be improved. The metrics the solution gathers can be limited and could be enhanced by giving more details."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"It is very expensive, but it's well worth the money."
"This product could be cheaper."
"The platform is expensive."
"Make sure you get the low down on your licensing and understand the licensing requirements before making a purchase, especially when it comes to an upgrade. Make sure that it suits your needs before you commit to it. For example, we purchased ATA at version 6.2.1. At that time, the licensing covered everything we need. NETSCOUT comes out with 6.2.2, stating that in order to upgrade, you had to purchase CyberStream licensing. Now that requires some additional funding from both a capital investment and a maintenance cost. That's something that should have been said, "Well, if you want these additional features, you will need to purchase these CyberStreams." Otherwise, we should be allowed to continue on the basic operations as it is now through the newer releases without being stuck."
"It can be expensive, but if you have a good configuration, based on what you are looking for, it's okay, it's manageable."
"Like any company, we always want better pricing. The pricing is okay, but it's not a cheap solution. When you want to deploy it across an enterprise as large as ours, you go into seven figures. It's not a cheap solution to get out there."
"There is a need to make yearly payments towards the licensing charges attached to the product. The product may come across as a cheap tool for some, while it may seem costly for others."
