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

"Thanks to the Riverbed Steelcentral AppResponse technology our remote services are now focused on monitoring the End User satisfaction instead of watching only the infrastructure."
"The most valuable feature of Alluvio AppResponse is the actual response time for measuring performance."
"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."
"Very easy to use and gather value from the start."
"The most valuable feature is performance monitoring."
"When it comes to the ability to scale up the product, this is suitable for small medium and large environments, PPG and Volkswagon being examples."
"Riverbed's product is a superb product."
"Opnet probes (AppResponse Xpert), now part of Riverbed, capture network traffic and calculate automatically many applicative and network KPI."
"They have very accurate and fast support."
"Nagios is my favourite open source monitoring system."
"The solution is pretty stable."
"The solution's most valuable feature is its simplicity."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"I can monitor a phone on a desk to very big servers of any company."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
 

Cons

"Marketing is complex and not well understood, so often this product is not considered a good fit just for a surface look."
"Technical support needs to be more responsive."
"The licenses are costly and are done per module."
"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."
"Need to bring back the NetFlow module for AppResponse."
"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 pricing is on the higher side of things. If they could lower it, that would be ideal."
"Disks are heavily used for traffic capture and may break times to times but RAID feature avoids any production pause."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"There's room for improvement in the visibility, and in the ability to extract information."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"Business services monitoring is still really basic."
"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."
"The reporting structure could be more streamlined."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
 

Pricing and Cost Advice

"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 is costly for small and medium businesses."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"As it is not an agentless tool, I think it is expensive."
"The licensing fees for this solution are approximately $3,000 USD per year."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
