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.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"We really like the scalability capabilities."
"The most valuable feature of Alluvio AppResponse is the actual response time for measuring performance."
"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."
"The most valuable feature is performance monitoring."
"With some APM solutions, it can take a long time to check a periodic report, but you can get all the necessary details quickly with AppResponse."
"Riverbed's product is a superb product."
"It provides us with complete visibility of every packet."
"The dashboard allows you to see what's going on in the overall system."
"The solution has a lot of plugins and scripts integrated with it."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"It's great for monitoring IT services infrastructure."
"The installation is no problem. I've installed Nagios several times."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements. It is flexible and easy to integrate with our systems. You can customize the solution by adding additional features using code."
"This is a very good solution and it is simple to use, for any company."
 

Cons

"The pricing is on the higher side of things. If they could lower it, that would be ideal."
"They need to better integrate with products and solutions from different vendors."
"Technical support needs to be more responsive."
"The AI features should be addressed in respect of the analysis and intelligence that must be supported and delivered in the tool to predigest the large amounts of data."
"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."
"Need to bring back the NetFlow module for AppResponse."
"The reporting models need improvement as most of the time, we have to customize the reports manually."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"Nagios XI can improve its GUI for users with a new look."
"It can be quite difficult to know which drivers and agents to use when setting up."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The interface could be more user-friendly."
"The user interface needs improvement."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
 

Pricing and Cost Advice

"It is costly for small and medium businesses."
"The solution is no more expensive than other products."
"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."
"Nagios XI is open source."
"We are using the free version of this solution."
"Nagios XI is an expensive solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The pricing is high with separate licensing for the product and support."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
