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

"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"Nagios has good scalability."
"All of them, but mainly: Highly-efficient server performance monitoring engine Configuration wizards Infrastructure management Configuration snapshot."
"The solution is pretty stable."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"It's great for monitoring IT services infrastructure."
"It's very easy to install it and manage it with Nagios XI's interface."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"In comparison with most monitoring software, this software is incredibly easy to use."
"The support from Pandora FMS is legendary."
"Thanks to this software and to the work of the support team, we have everything under control."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"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."
"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."
 

Cons

"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"There are stability issues if you have a large number of hosts and services."
"The product's stability could be even better."
"The installation and monitoring need improvement."
"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."
"The Configuration Wizard needs improvement, because not all vendors are present."
"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 important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"The product lacks APIs for integration with other systems."
"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 open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
