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. It also allows us to schedule downtime and maintenance."
"Nagios is great for verify quality and quantity in a datacenter."
"Nagios is the best monitoring tool that I have ever worked on."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Overall, it's a powerful system."
"I really found Nagios a perfect fit for us and a good product to work with."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The alerting system is very effective."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"What I value most about Pandora FMS is the simplicity of working with it."
"The network monitoring and configuration within this solution is very good."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"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."
 

Cons

"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"The Configuration Wizard needs improvement, because not all vendors are present."
"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."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"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."
"Nagios XI can improve its GUI for users with a new look."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Pandora could deliver better analytics out of the box."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"Third-party integration should be improved for some commonly used products."
"The price for Pandora FMS is expensive."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"The pricing is high with separate licensing for the product and support."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"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."
