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.

Quotes from Members

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

Pros

"This product helps us to monitor performance of these environments."

"Very easy to use and gather value from the start."

"It's a stable product. Riverbed has invested a significant amount of research and development into it, so it's a solid tool overall."

"Riverbed's product is a superb product."

"Excellent for strategic metrics and as a troubleshooting/analysis tool."

"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."

"I have found the AppResponse, which is a packet capture solution, very good. It gives you the ability to drill down back in time. You've got all the packets there. You can troubleshoot it later, not immediately. It's very interesting."

More Alluvio AppResponse pros

"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

More Nagios Core pros

Cons

"Alluvio AppResponse should improve its ability to expand across multiple operating systems."

"The licenses are costly and are done per module."

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

"They need to better integrate with products and solutions from different vendors."

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

"Marketing is complex and not well understood, so often this product is not considered a good fit just for a surface look."

"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."

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

More Alluvio AppResponse cons

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."

"Application level monitoring is limited."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"They should simplify the features so it becomes easier to setup out of the box."

"There is room for improvement in the graphics."

"Default interface is clunky and slow."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

More Nagios Core cons
