Quotes from Members

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

Pros

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"Nagios Core is stable."

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

"Dashboard provides monitor of total assets."

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

"Provides timely notifications."

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

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

More Nagios Core pros

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

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

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

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

Cons

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

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

"There is room for improvement in the graphics."

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

"The tool needs to improve the integrations."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"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."

"I would like to see more training videos."

More Nagios Core cons

"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."

"It requires some simplification."

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

Pricing and Cost Advice

"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."

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

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

"The product is cheaply priced."

"I would rate the solution's pricing an eight out of ten."

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

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

"Most the plugin features are free."

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."
