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.

"The solution has a lot of plugins and scripts integrated with it."
"I can monitor a software made in-house to software of bigger companies."
"Nagios is the best software of its kind if you have time for configure any host and network, and you can do quite everything with a bit of scripting."

Cons

"I feel that the maturity and user interface needs to be improved."
"We're still experiencing stability issues with regards to collecting performance graphs."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"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."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"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."
"We would like to see improvement in the mainframe integration that this solution is capable of."

"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."
 

Pricing and Cost Advice

"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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 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."
