Quotes from Members

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

Pros

"We can get real time statistics of our servers which improves our monitoring."

"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."

"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"The application performance monitoring feature is valuable."

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

More Nagios Core pros

"When it comes to customization, Micro Focus is more mature than its competitors."

"We can detect non-compliant devices and automate remediation actions to cover the gap in the configuration standards."

"The solution enables dynamic discovery and incorporates a powerful configuration management database, CMDB, along with a strong correlation engine."

Cons

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"The configuration and reporting modules need to be improved."

"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."

"Application level monitoring is limited."

"The interface could be improved."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

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

"The UI is a little outdated and graphics could be displayed in a better way."

More Nagios Core cons

"Micro Focus Network Management doesn't support end-to-end monitoring of cloud infrastructure. Micro Focus might have different cloud solutions for cloud automation and hybrid cloud management. There are a lot of products that also support automation. That is different, but it should monitor the cloud from an IT operations management perspective."

"It may need a more customizable UI."

"The user interface is outdated and needs improvement, especially for service and topology maps."

"Micro Focus Network Management doesn't support end-to-end monitoring of cloud infrastructure."

Pricing and Cost Advice

"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."

"The solution is expensive."

"Most the plugin features are free."

"The product is cheaply priced."

"It's free."

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

"Nagios Core is an open source solution, and there are no licensing fees."

More Nagios Core pricing and cost advice

"Micro Focus' price is on the higher side, but there are other products like CA products and IBM that are more expensive. At the same time, you have to compare the maturity level of the solutions."
