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.

Personalized metrics; simplicity of data
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's very easy to install it and manage it with Nagios XI's interface."
"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 has good scalability."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"This is a very good solution and it is simple to use, for any company."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"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."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Network monitoring is fun again with Pandora FMS."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"In comparison with most monitoring software, this software is incredibly easy to use."
"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."
"The support from Pandora FMS is legendary."
 

Cons

"Technical support is an area that needs improvement. It is not available 24/7."
"The interface could be more user-friendly."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"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."
"However, it is a bit complex and difficult for a first-time user."
"They need to develop a better integration with a common ticketing system will be great."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"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."
"I think some improvements to the Android app would be good."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"This solution requires proper training to get 100% out of it."
 

Pricing and Cost Advice

"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."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"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."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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 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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
