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 a simple monitoring tool with performance management."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"It has a lot of flexibility for customization and a wide range of metrics."
"It's an essential part of our infrastructure, and we'll keep using it."
"I can monitor a software made in-house to software of bigger companies."
"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."
"This solution has screens that are easy to understand and provide a wealth of information."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"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."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"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."
"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."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
 

Cons

"While the UI is functional, I have always thought there was room for improvement here."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"I would like to see support for notification via SMS."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The Configuration Wizard needs improvement, because not all vendors are present."
"We'd like to see more integration capabilities."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Improvements are needed for server and network discovery, including service-based discovery."
"This solution requires proper training to get 100% out of it."
"The product lacks APIs for integration with other systems."
"Improvements are needed for server and network discovery, including service-based discovery."
"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."
"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

"As it is not an agentless tool, I think it is expensive."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
