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

"I really found Nagios a perfect fit for us and a good product to work with."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It's great for monitoring IT services infrastructure."
"Nagios is my favourite open source monitoring system."
"The technical support is good."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"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."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"What I value most about Pandora FMS is the simplicity of working with it."
"The support from Pandora FMS is legendary."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"For some, it may be difficult to deploy."
"Business services monitoring is still really basic."
"The Configuration Wizard needs improvement, because not all vendors are present."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Its simple deployment but complexity comes once you have to import more plugins."
"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."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"It would be helpful to include the generation of reports for times that the network was out of service."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"This solution requires proper training to get 100% out of it."
"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."
"The price for Pandora FMS is expensive."
"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."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"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

"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"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 XI is open source."
"We are using the free version of this solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"As it is not an agentless tool, I think it is expensive."
"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 Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"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."
"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."
