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 allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"It is an open-source platform with valuable features for performance and stability."
"Nagios XI is stable."
"For anyone who is interested in using this solution, I would recommend it."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"It's great for monitoring IT services infrastructure."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"I can monitor a software made in-house to software of bigger companies."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"Network monitoring is fun again with Pandora FMS."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"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."
"It provides us with proactive monitoring and is very easy to configure and maintain."
 

Cons

"The Configuration Wizard needs improvement, because not all vendors are present."
"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."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The interface could be more user-friendly."
"They need more documentation for the plugins."
"However, it is a bit complex and difficult for a first-time user."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"I think some improvements to the Android app would be good."
"This solution requires proper training to get 100% out of it."
"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."
"The price for Pandora FMS is expensive."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
 

Pricing and Cost Advice

"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Licensing costs are reasonable."
"We are using the free version of this solution."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
