Flexibility and detailed performance stats enable effective network monitoring
Spectrum is very good at monitoring all network faults and configurations. It enables me to take action based on network issues. The Performance Management provides detailed network performance stats, including CPU, memory, and interface bandwidth. Additionally, Spectrum is flexible and allows me to organize and treat devices uniquely without impacting other devices.

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.

Quotes from Members

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

Pros

"We're able to present data from multiple back-end collection sources into a single dashboard for the users. So they don't have to go to multiple locations to get data about a particular item, or device."
"The most valuable of CA Performance Management is consolidated network infrastructure monitoring and reporting."
"There is a good amount of vendor certification which comes with the product. That's all factory-loaded, no need to load any custom-made files. Most of the metrics are calibrated and captured from the devices based on the defaults available from vendor certification."
"It gave us one location, one place to do all of group administration, and to build dashboards, and device administration, inventory counts... it really reduced our overall administrative overhead."
"You can have thousands of devices inside and hundreds of thousands of interphases without a problem."
"There is another component of the tool called Network Flow Analysis. It gives us the ability to troubleshoot issues which do not appear right away."
"​The ability to quickly do drag and drop customized reports for dashboards.​"
"It makes things faster when we have our network operations center, they can look at their dashboards that we've created for them, and they can see problems immediately."
"Valuable features include data threat detection, network analytics, and overall bandwidth monitoring."
"The packet flow switch is the most valuable aspect of the solution."
"These vendor interlocution situations have gone from a couple of weeks to a couple of days."
"We build application dashboards and performance indexes for locations, and this solution provides us with increased visibility while conducting IT deployments, such as data migration."
"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."
"The most valuable feature is visibility."
"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."
"It helps us get to the root cause quickly. It helps us find massive error codes, then we drill down on that error code, knowing that is the source of our problem."
 

Cons

"DX Performance Management should increase high availability. If one of my two data centers goes offline and the other is operational, I need a seamless transition from the primary to the secondary data center. It's crucial to maintain consistent monitoring of the devices during this transition. Therefore, I require continuous, 24/7 monitoring of my system using this tool."
"This tool gathers so much data, which makes it hard to convert over. To upgrade it, you really need the solution backed up. That is the issue that we are facing right now."
"It could be a little easier to integrate new metrics."
"What we want to see: More integration inside of Spectrum and integration of role-based access."
"Product has issue collecting IP SLA data."
"I would say the initial setup is complex."
"There are some issues. We started supporting UTA and began to see both major and minor problems."
"Since we are out of registered IP space, we are moving to ipv6 and we expect our vendors to move with us, and they have not delivered yet."
"I think it could have an easier to understand interface."
"For the most part, it's relatively stable. However, there are some times where it seems like it runs a little slow and you have to reset things to get it back going again."
"Comparing this to a vendor like Cisco, who provides any component next business day, NETSCOUT nGeniusONE took a long time."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"We don't use the single pane of glass view, even though we own it."
"There's a little too much investigation that the user has to do at this point."
"For individual subscriber tracings, sometimes it does not capture all the messages. There is a little bit of room for improvement there."
"Being able to manage the packet flow switches in nGeniusONE would be great."
 

Pricing and Cost Advice

"Do your homework and know how many devices you will be managing out of the gate. Be sure to project what your growth will be each year."
"The tool's pricing is based on the number of network devices."
"We were looking at other vendors in the marketplace for NetFlow, and CA just beat everybody else in price, cost, and the size to implement. ​"
"They should provide more scalable licensing for the product."
"We purchase a license to use the solution every three years and we have multiple contracts. They have been increasing the price annually. We have a baseline for three years and then we need to pay the difference from the baseline, and we are in the process of negotiating a new price for all the licenses we need. The price overall is affordable."
"I like the licensing model because it's device-based."
"The biggest problem we have with this product is the expense."
"The platform is expensive."
"I don't know what the cost to buy the solution was, but I doubt if it's a significant part of the budget as far as the maintenance and support are concerned."
"If you are able and you are willing to use everything that Netscout provides to you, it's probably a relatively fair price. The problem is that it's such a large and such a complex tool that I'm not sure that many companies would be able to use it entirely, the way it's expected to be used."
"The scalability becomes very expensive quickly."
"Cost is probably the biggest drawback. Compared to some of the newer vendors that have popped up in the space, it's definitely more on the expensive side... [But] it's been able to keep its value, even in the face of the cheaper competition."
"It is very expensive, but it's well worth the money."
"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."
