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 solution has a lot of plugins and scripts integrated with it."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"It's great for monitoring IT services infrastructure."
"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."
"For anyone who is interested in using this solution, I would recommend it."
"It's an essential part of our infrastructure, and we'll keep using it."
"I really found Nagios a perfect fit for us and a good product to work with."
"Nagios XI is stable."
"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."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"What I value most about Pandora FMS is the simplicity of working with it."
"This solution has screens that are easy to understand and provide a wealth of information."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."
 

Cons

"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"I would like to see support for notification via SMS."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"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."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Third-party integration should be improved for some commonly used products."
"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 would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"Pandora could deliver better analytics out of the box."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"I think some improvements to the Android app would be good."
 

Pricing and Cost Advice

"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios XI is an expensive solution."
"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 pricing is high with separate licensing for the product and support."
"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."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
