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.

Cons

"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."

Pricing and Cost Advice

"We are using the free version of this solution."
"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."
"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 pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
