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 features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"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 most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios is the best software of its kind if you have time for configure any host and network, and you can do quite everything with a bit of scripting."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"The support is excellent for this product; their response time is very fast, and they are very knowledgeable."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"You can configure several types of architecture for high availability or load balancing."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
 

Cons

"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"The Configuration Wizard needs improvement, because not all vendors are present."
"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 way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"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."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"This solution requires proper training to get 100% out of it."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
 

Pricing and Cost Advice

"We are using the free version of this solution."
"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."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"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."
