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 alerting system is very effective."
"Nagios XI is stable."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"Nagios XI helped me to draw the network and check for system failures."
"It has a lot of flexibility for customization and a wide range of metrics."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"We are able to control our business with this all-in-one monitoring tool."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"Network monitoring is fun again with Pandora FMS."
"Thanks to this software and to the work of the support team, we have everything under control."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"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."
"In comparison with most monitoring software, this software is incredibly easy to use."
"The most valuable feature is that it is an all-in-one monitoring system."
 

Cons

"There's room for improvement in the visibility, and in the ability to extract information."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Open-source software is usually not user-friendly."
"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."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"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 product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"We are using the free version of this solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
