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

"Nagios is great for verify quality and quantity in a datacenter."
"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 has a lot of flexibility for customization and a wide range of metrics."
"The most valuable feature is the monitoring of processes."
"Overall, it's a powerful system."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"The solution has a lot of plugins and scripts integrated with it."
"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."
"You can configure several types of architecture for high availability or load balancing."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"This solution has screens that are easy to understand and provide a wealth of information."
"What I value most about Pandora FMS is the simplicity of working with it."
"The support from Pandora FMS is legendary."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"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."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
 

Cons

"Nagios XI can improve its GUI for users with a new look."
"For some, it may be difficult to deploy."
"Nagios XI isn't really good for scaling, in my experience."
"The Configuration Wizard needs improvement, because not all vendors are present."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"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."
"I would like to see support for notification via SMS."
"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."
"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."
"It would be helpful to include the generation of reports for times that the network was out of service."
"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."
"Third-party integration should be improved for some commonly used products."
"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."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"This solution requires proper training to get 100% out of it."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"Licensing costs are reasonable."
"Nagios XI is open source."
"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."
"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."
"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."
"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 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."
