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 dashboard allows you to see what's going on in the overall system."
"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."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"It has a lot of flexibility for customization and a wide range of metrics."
"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."
"It is an open-source platform with valuable features for performance and stability."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"The support from Pandora FMS is legendary."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"The solution has good dashboards and graphics."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"We are able to control our business with this all-in-one monitoring tool."
"You can configure several types of architecture for high availability or load balancing."
"This solution has screens that are easy to understand and provide a wealth of information."
 

Cons

"I would like to see more customization in the network map because it is a bit tricky to use it."
"I would like to see support for notification via SMS."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Implementation on Windows was painful."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"An update to the Android app would be appreciated."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
 

Pricing and Cost Advice

"Nagios XI is an expensive solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"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 Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
