Identifies and analyzes performance issues quickly using in-built AI and ML

With Alluvio AppResponse, there is an in-built analytical analysis with AI and ML, which identifies and provides data such as the number of TCP retransmits, web access time, total connection time out, total connections established, and server-side errors. The RTCC response time composition chart is crucial because it helps pinpoint the issue's origin, whether from the server, network, or application side. It's a superb product when compared to SolarWinds SAM, which is agent-based, while Alluvio AppResponse captures all traffic from the core switch.

Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Quotes from Members

"The most valuable feature of Alluvio AppResponse is the actual response time for measuring performance."

"It provides us with complete visibility of every packet."

"Ability to see end to end user, application, server, and network response time and throughput data."

"When it comes to the ability to scale up the product, this is suitable for small medium and large environments,"

"AppResponse is a total solution that gives you end-to-end visibility into applications at all levels, from Layer 1 to Layer 7. We can trace all those sections: physical, IP, transport, presentation, application, etc. It gives us the full picture."

More Alluvio AppResponse pros

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"This solution allows us to see exactly what is going on in the network and we can very quickly solve issues with users."

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

Cons

"Need to bring back the NetFlow module for AppResponse."

"The pricing is on the higher side of things. If they could lower it, that would be ideal."

"The initial setup is straightforward, but you have to know a little about the product. It's not for everybody to just plug and play. If you know how the solution is implemented then it is straightforward."

"The recent changes in corporate structure may have caused some decrease in support quality."

"If Alluvio AppResponse reduces its cost, it will be more beneficial for customers to monitor their application and network performance."

"Technical support needs to be more responsive."

More Alluvio AppResponse cons

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

Pricing and Cost Advice

"It is costly for small and medium businesses."

"The licensing model is expensive compared to its competitors, but the service it gives to your business, and the data quality, means that it's worth it."

"The price is a little bit high, especially because we have to pay an import tax."

"The solution is no more expensive than other products."

"It's quite expensive."

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."
