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.

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"The overall performance of the product is superb."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"It has a lot of flexibility for customization and a wide range of metrics."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The technical support is good."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"The solution has good dashboards and graphics."
"The network monitoring and configuration within this solution is very good."
"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."
"Pandora FMS is an all-in-one solution that is cost-efficient."
"What I value most about Pandora FMS is the simplicity of working with it."
"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 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."
 

Cons

"The installation can get very difficult depending on what Linux flavour you are using."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"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."
"For some, it may be difficult to deploy."
"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."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"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."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"A nice feature in the next release would be an automation module to run workflow actions."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"The price for Pandora FMS is expensive."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"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."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
