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

"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"I can monitor a software made in-house to software of bigger companies."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"The solution is pretty stable."
"You can configure several types of architecture for high availability or load balancing."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"What I value most about Pandora FMS is the simplicity of working with it."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
 

Cons

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"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."
"We'd like to see more integration capabilities."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The product does not have SAP monitoring."
"Open-source software is usually not user-friendly."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"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."
"The price for Pandora FMS is expensive."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"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."
"An update to the Android app would be appreciated."
"It would be helpful to include the generation of reports for times that the network was out of service."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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 licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"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."
