Proactive monitoring has improved uptime and now detects performance issues before users suffer

The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows. Better navigation, integration, and more intuitive customizations for the dashboard and alerts would improve the overall operational experience. Dashboard customizations and reporting flexibility represent another improvement area. More advanced visualization options and an easier way to create tailored operational dashboards would help the team analyze trends and share insights more effectively. The integration ecosystem could also be expanded further, especially for modern DevOps and cloud-native workflows. Stronger native integrations with collaboration tools, observability platforms, and CI/CD pipelines would make it easier to fit into the evolving engineering environment. It would also help to have more automation-friendly capabilities such as easier API-based configurations, management, and infrastructure as code support for monitor provisioning. That would make large-scale monitoring management more efficient for the DevOps team. From a support perspective, the experience has been generally stable, but faster turnaround times for more complex technical issues and more detailed troubleshooting guidance would be beneficial. Improved documentation and more advanced implementation best practices for enterprise-scale deployment would also help the team onboard and optimize the platform more effectively. AlertSite would benefit from continued modernizations in a few areas. The biggest improvement would be a more intuitive and modern user experience for configuring monitoring, managing alerts, and navigating dashboards, especially in larger environments with many monitored services. Stronger integrations with modern cloud-native DevOps ecosystems including better automation support, richer APIs, and easy integration with CI/CD pipelines and observability platforms would also be helpful. Another improvement area is intelligent alert management. Features such as smart alert correlations, anomaly detections, and noise reduction would help operations teams focus on the most critical incidents more effectively.

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

"There are custom reports available along with the inbuilt reports."

"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."

"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."

"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."

"The alerting capabilities of AlertSite were really helpful."

"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."

"This solution has numerous advantages; it's extremely simple to configure, and either digital monitors or single-URL monitors are simple to configure and build."

"I highly recommend AlertSite to other users."

More AlertSite pros

"Because we are doing proactive monitoring instead of reactive, the end users don't even see that there is something wrong."

"In my opinion, we've been able to solve problems before they've become a big issue, which is the main reason anybody would want visibility into their network: If you have fewer people yelling at you, you're doing your job."

"The most valuable feature of this solution is being able to drill down into any kind of troubles that are reported to us, by use of identifiers."

"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."

"Visual TruView helped our network team respond to potential issues before they became larger ones."

"It's an easy product to set up."

"The solution transforms packet wire data into real-time data that is ready to act on."

"If a lot of traffic from one site is hitting AWS Cloud or the data center, then we want to know which client is utilizing the most bandwidth. We will work with nGeniusONE to troubleshoot the issue."

More NETSCOUT Network & Application Observability pros

Cons

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."

"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."

"I would like the ability to get more data points with regard to some of the unique requirements that we have."

"The user interface and configuration experience could be more modern and streamlined in some areas, especially when managing a large number of monitors or creating complex monitoring workflows."

"AlertSite requires improvements related to security, even at the enterprise level."

"It is not compatible with all of the product platforms that we use."

"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."

"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."

More AlertSite cons

"Some help screens would be nice, especially if we bring on new operators. It would be great to see if they have more helpful tips available."

"For individual subscriber tracings, sometimes it does not capture all the messages. There is a little bit of room for improvement there."

"Maybe the optics cost could be improved. It's not about the product itself, but the optics cost from other companies is very high, which affects the business. When you buy a $1 million product, you shouldn't be expected to pay $500,000 for support. So, support, operation, and professional services are very expensive. It's the main weakness."

"I'd like them to make the product more user-friendly."

"One area that could be improved is the reporting features. In the version transformation from ten to eleven, the platform changed from a Windows-based platform to a Linux-based platform. As a result, the previous reporting feature using Crystal Reports was no longer available. Instead, we had to generate PDF dashboard reports, which were not as flexible."

"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."

"One of the products we use is SolarWinds, and it provides a very cool mapping of an agent from end-to-end. If NETSCOUT could somehow implement that into their design... make it quicker and easier to get those net paths, it would be huge."

"The solution is not great, but it is not bad."

Pricing and Cost Advice

"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."

"The cost is high."

"We purchased the license once and had the option of selecting the number of user licenses."

"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."

"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."

"I rate the price of NETSCOUT nGeniusONE a four out of five."

"The license becomes cost prohibitive very quickly."

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."

"The product is too expensive compared to other products."

"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."

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."
