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

"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"I can monitor a phone on a desk to very big servers of any company."
"The dashboard allows you to see what's going on in the overall system."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"An excellent solution that is easy and intuitive to implement."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"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 technical support is good."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"The most valuable feature is that it is an all-in-one monitoring system."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"What I value most about Pandora FMS is the simplicity of working with it."
"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, and it's also scalable enough to support large environments."
 

Cons

"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"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."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"The interface could be more user-friendly."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"They need to develop a better integration with a common ticketing system will be great."
"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 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."
"I think some improvements to the Android app would be good."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"A nice feature in the next release would be an automation module to run workflow actions."
"It would be helpful to include the generation of reports for times that the network was out of service."
"The price for Pandora FMS is expensive."
"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."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"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."
"Nagios XI is open source."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
