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 is easy to install, which sets it apart from other open-source solutions I've tried."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"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 allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"An excellent solution that is easy and intuitive to implement."
"The ROI is very good."
"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."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"In comparison with most monitoring software, this software is incredibly easy to use."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"This solution has screens that are easy to understand and provide a wealth of information."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"Thanks to this software and to the work of the support team, we have everything under control."
 

Cons

"However, it is a bit complex and difficult for a first-time user."
"I would like to see support for notification via SMS."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"For some, it may be difficult to deploy."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"While the UI is functional, I have always thought there was room for improvement here."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"We would like the real-time monitoring of an interface to be improved within this solution."
"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."
"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."
"Pandora could deliver better analytics out of the box."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"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."
 

Pricing and Cost Advice

"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."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"We are using the free version of this solution."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"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."
"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 get the license and it includes updates, new versions, and access to the complete library of modules."
