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 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."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"The solution is pretty stable."
"Nagios XI is stable."
"The technical support is good."
"Nagios is the best monitoring tool that I have ever worked on."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"In comparison with most monitoring software, this software is incredibly easy to use."
"This solution has screens that are easy to understand and provide a wealth of information."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
 

Cons

"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The installation can get very difficult depending on what Linux flavour you are using."
"They need more documentation for the plugins."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"I think some improvements to the Android app would be good."
"A nice feature in the next release would be an automation module to run workflow actions."
"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."
"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."
"The price for Pandora FMS is expensive."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
