Quotes from Members

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

Pros

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."

"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."

"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."

"We've got a medium size distributed system with a lot of locally installed machines, and Nagios provides us with a solid and reliable monitoring solution for these machines."

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

More Nagios Core pros

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

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

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

Cons

"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."

"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

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

"Would benefit from aggregations if a particular server goes down."

More Nagios Core cons

"The user interface is outdated and needs improvement, especially for service and topology maps."

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."

Pricing and Cost Advice

"Nagios Core is free to use."
