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.

My primary use case for Pandora is monitoring This solution has helped us improve our organization by allowing us to create a lot of metrics on several platforms, including Windows, Linux, and Unix. We then use these Pandora metrics to create an interface. We then pass the interface off to the…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"The alerting system is very effective."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Nagios XI is stable."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"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."
"You can configure several types of architecture for high availability or load balancing."
"In comparison with most monitoring software, this software is incredibly easy to use."
"Pandora FMS is an all-in-one solution that is cost-efficient."
 

Cons

"Nagios provides most of the features by default, however to add more services to it, it requires additional plugins which require little effort on administrative end."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The GUI could be improved."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"For some, it may be difficult to deploy."
"They need to develop a better integration with a common ticketing system will be great."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"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 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."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"Improvements are needed for server and network discovery, including service-based discovery."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"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."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"We are using the free version of this solution."
"Nagios XI is an expensive solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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 get the license and it includes updates, new versions, and access to the complete library of modules."
