A cost-effective solution to monitor customer networks

We are not getting any issues with the integrations. Versa Director is the fastest engineering tool and is ideal for use without product management. People must rely on and utilize it to enhance anything they want to increase, as it helps minimize the product. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"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."

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."

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

"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."

"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."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"Extensibility is good as this makes it easy to write checks on your own."

More Nagios Core pros

"The most valuable functionality is some of the policy pieces that are quite useful."

"The most valuable feature of Versa Director is analytics."

"Versa Director's best feature is the ease of configuration and customer and vendor management."

"Versa Director is the fastest engineering tool and is ideal for use without product management."

Cons

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

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"The dashboard should be improved."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

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

"The initial setup process could be easier."

"The tool needs to improve the integrations."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

More Nagios Core cons

"It requires some simplification."

"Versa Director's deployment process is not the best."

"Versa could be more AI-oriented."

"What needs improvement in Versa Director is maturity because, from an operating point of view, it's not mature enough. You'll still need to do a lot of research on Versa Director, so if it could mature faster, that would be very good."

Pricing and Cost Advice

"Most the plugin features are free."

"We are using the free version of Nagios Core."

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

"It's free."

"The product is cheaply priced."

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

"Nagios Core is a cheap solution."

"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

"Having to buy separate licenses for the on-prem SD-WAN hardware and SSL VPN software makes Versa Director very costly compared to other solutions like Fortinet and Cisco."
