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

"The most valuable feature is the monitoring of processes."
"The alerting system is very effective."
"The installation is no problem. I've installed Nagios several times."
"Nagios has good scalability."
"Nagios XI is stable."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It's an essential part of our infrastructure, and we'll keep using it."
"The solution's most valuable feature is its simplicity."
"The network monitoring and configuration within this solution is very good."
"Thanks to this software and to the work of the support team, we have everything under control."
"You can configure several types of architecture for high availability or load balancing."
"Pandora's architecture is interesting; it's open so you can easily extend and enhance it, it's simpler to customize Pandora compared to other solutions, and it's also scalable enough to support large environments."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"The solution has good dashboards and graphics."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"We are able to control our business with this all-in-one monitoring tool."
 

Cons

"Its simple deployment but complexity comes once you have to import more plugins."
"The product's stability could be even better."
"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."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"For some, it may be difficult to deploy."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"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."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"A nice feature in the next release would be an automation module to run workflow actions."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"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."
"Improvements are needed for server and network discovery, including service-based discovery."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"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."
"Licensing costs are reasonable."
"We are using the free version of this solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"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."
"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."
