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

"I can monitor a software made in-house to software of bigger companies."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"It's great for monitoring IT services infrastructure."
"The most valuable feature is the monitoring of processes."
"It has a lot of flexibility for customization and a wide range of metrics."
"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."
"They have very accurate and fast support."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"You can configure several types of architecture for high availability or load balancing."
"This solution has screens that are easy to understand and provide a wealth of information."
"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."
"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."
"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."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
 

Cons

"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"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."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The installation can get very difficult depending on what Linux flavour you are using."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"The Configuration Wizard needs improvement, because not all vendors are present."
"Pandora could deliver better analytics out of the box."
"An update to the Android app would be appreciated."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I think some improvements to the Android app would be good."
"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 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."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"We are using the free version of this 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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"The pricing is high with separate licensing for the product and support."
"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."
"As it is not an agentless tool, I think it is expensive."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"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."
