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

"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"Nagios is the best monitoring tool that I have ever worked on."
"The network monitoring and configuration within this solution is very good."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"You can configure several types of architecture for high availability or load balancing."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"The most valuable feature is that it is an all-in-one monitoring system."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"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."
 

Cons

"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"There are stability issues if you have a large number of hosts and services."
"It's in need of more standard plug-ins."
"The product's stability could be even better."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The installation and monitoring need improvement."
"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."
"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."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"This solution requires proper training to get 100% out of it."
"Pandora could deliver better analytics out of the box."
"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."
"Improvements are needed for server and network discovery, including service-based discovery."
"We would like the real-time monitoring of an interface to be improved within this solution."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Nagios XI is an expensive solution."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."
