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

"The solution is pretty stable."
"The technical support is good."
"Nagios XI is stable."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"I can monitor a phone on a desk to very big servers of any company."
"The most valuable feature is the monitoring of processes."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"What I value most about Pandora FMS is the simplicity of working with it."
"The network monitoring and configuration within this solution is very good."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The solution has good dashboards and graphics."
"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. It's also scalable enough to support large environments."
"This solution has screens that are easy to understand and provide a wealth of information."
 

Cons

"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"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'd like to see more integration capabilities."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"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."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"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 product lacks APIs for integration with other systems."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"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."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I think some improvements to the Android app would be good."
"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."
"This solution requires proper training to get 100% out of it."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"The pricing is high with separate licensing for the product and support."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
