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.

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"Nagios XI is a simple monitoring tool with performance management."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution's most valuable feature is its simplicity."
"It's great for monitoring IT services infrastructure."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"Nagios XI helped me to draw the network and check for system failures."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"Network monitoring is fun again with Pandora FMS."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The solution has good dashboards and graphics."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"Implementation on Windows was painful."
"The product's stability could be even better."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"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."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"Third-party integration should be improved for some commonly used products."
"Pandora could deliver better analytics out of the box."
"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"You get the license and it includes updates, new versions, and access to the complete library of modules."

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…
