The solution is useful for monitoring network devices, but the interface is old-fashioned
The solution is useful for monitoring network devices We use it for up-and-down monitoring features. It’s an old solution. It has an old-fashioned interface. The product must provide a compliance testing feature. I have been using the solution for six years. I rate the tool’s stability a ten…

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

"I have found that it has a good GUI and user-friendly administration."
"Network tracking is the most valuable feature of Network Analyzer."
"The solution is useful for monitoring network devices."
"The solution offers very good system monitoring; it's easy to manage your network, as well as your hardware and software, and it's really useful."
"Since we have been using it for the last five years we have done very well with reference to ROI."
"The tool's UI is user-friendly, and pricing is affordable. It is very easy to deploy and learn."
"Its initial setup process is straightforward."
"The network monitoring feature, especially, stands out to me."
"The biggest benefit is the ability to do low-level packet inspection. When I say packet inspection, I don't mean looking at payload, but just looking at your communication handshakes and the like. It reduces troubleshooting time because you can get a much better view into the communications path between servers, database servers, web servers, and understand what's going on."
"We've saved a lot of time in triaging. We have found root cause identities on packet captures and have been able to feed that information back to a specific vendor, because a lot of our technology is emerging. So, we're able to give that feedback to our vendors and have them solve the problems that they need to fix, and they have the evidence to do so."
"Proactive versus a customer having a bad experience: That is the key point."
"The quick drill-down views are similar to Wireshark views. Those are quite nice, with the views on how you interpret some of the data. The granularity of how far you can drill down into milliseconds or microseconds is a very nice feature. It actually stores quite a lot of data in its database."
"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."
"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."
"These vendor interlocution situations have gone from a couple of weeks to a couple of days."
"If you are looking for a good application monitoring and packet analysis tool, you can strategically use NETSCOUT to get it done."
 

Cons

"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"I think the reports can be improved. They're adopted."
"It's very hard to install materials. You need a lot of documentation. They should make it easier to install and configure the solution."
"The graphics and reports can be a little bit better."
"It has an old-fashioned interface."
"There are some loopholes you need to be aware of from a security perspective."
"The bandwidth for its front-end version needs enhancement."
"There is room for improvement on the setup side."
"The single pane of glass feed still needs work."
"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."
"Usability is the area with the biggest room for improvement. We've found that with NETSCOUT, while it's a fantastic product, the usability is a major factor because there are just way too many clicks. It's obvious, from our experience, that the people who are developing the product aren't using it."
"The product is a little complicated."
"The scalability is difficult. Packet capture and packet broker are hard to do because you ultimately have to build a separate overlay network, so you can capture the packets."
"The initial deployment is tedious and requires a lot of build, deployment and configuration time. Experience is key to a successful deployment."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"I would like to see improvement in the user experience. It's hard to manage it."
 

Pricing and Cost Advice

"The solution is cost-efficient."
"They charge around ten thousand per month for one thousand nodes. That is their overall cost, but it differs on which company you are applying to, whether you are a service provider or an enterprise."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"I rate the price of NETSCOUT nGeniusONE a four out of five."
"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."
"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."
"The product is too expensive compared to other products."
"It was pretty modest because you could get it in different ways. I think the six licenses, at that time, were about $1,000 each. But then again, I work for a school and educators tend to get discounts on things. So maybe it cost us about five or six hundred a copy."
"It is a little overall pricey and expensive, but you get what you pay for."
"The tool's price is okay. On a scale of one to ten, I rate it as a five, where one means it is not expensive, and ten means it is the most expensive."
"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."
