Quotes from Members

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

Pros

"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."

"The reporting structure and the feature set are valuable to me."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Inspite of this limitation it is a fantastic product to use at zero cost"

"Its an awesome product to use."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."

More Nagios Core pros

"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."

"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."

"The solution has good dashboards and graphics."

"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."

"Features I have found most valuable with Pandora are the personalized metrics and the simplicity of data."

More Pandora FMS pros

Cons

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"The mapping is a little hard."

"They should simplify the features so it becomes easier to setup out of the box."

"I like to have the option to configure Nagios using the web interface."

"The user interface could be more interactive because it is pretty basic."

"We're using the free version, which limits us in terms of the things that we can do."

"The alerting mechanism in Nagios Core could be improved."

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

More Nagios Core cons

"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."

"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."

"I think some improvements to the Android app would be good."

"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."

"The product lacks APIs for integration with other systems and we have issues with monitoring."

"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."

"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."

More Pandora FMS cons

Pricing and Cost Advice

"We are using the open-source, unpaid version."

"Most the plugin features are free."

"It's free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."

More Nagios Core pricing and cost advice

"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."

"Pandora FMS is easy to implement and the pricing of licenses is competitive."

"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."

"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."

"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."

"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
