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 installation is no problem. I've installed Nagios several times."
"We love Nagios XI due to the fact that JPS Web is very useful."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"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."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The dashboard allows you to see what's going on in the overall system."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"We are able to control our business with this all-in-one monitoring tool."
"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. It's also scalable enough to support large environments."
"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."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
 

Cons

"The Configuration Wizard needs improvement, because not all vendors are present."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The Configuration Wizard needs improvement, because not all vendors are present."
"Nagios XI isn't really good for scaling, in my experience."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"Its simple deployment but complexity comes once you have to import more plugins."
"The installation can get very difficult depending on what Linux flavour you are using."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I think some improvements to the Android app would be good."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"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."
"We would like to see improvement in the mainframe integration that this solution is capable of."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
