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

"They have very accurate and fast support."
"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."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"The most valuable feature is the monitoring of processes."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability."
"I can monitor a phone on a desk to very big servers of any company."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"You can configure several types of architecture for high availability or load balancing."
"We are able to control our business with this all-in-one monitoring tool."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"The network monitoring and configuration within this solution is very good."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"Thanks to this software and to the work of the support team, we have everything under control."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
 

Cons

"There's no convenient way to manage notes as the only way is to manage them through the database."
"They need more documentation for the plugins."
"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."
"Business services monitoring is still really basic."
"Nagios XI can improve its GUI for users with a new look."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"We're still experiencing stability issues with regards to collecting performance graphs."
"The user interface needs improvement."
"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."
"An update to the Android app would be appreciated."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"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."
"This solution requires proper training to get 100% out of it."
"A nice feature in the next release would be an automation module to run workflow actions."
"We would like to see improvement in the mainframe integration that this solution is capable of."
 

Pricing and Cost Advice

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"As it is not an agentless tool, I think it is expensive."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Nagios XI is an expensive solution."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
