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

Pros

"My organization can leverage IDERA Uptime Infrastructure Monitor to learn more about how clients perform because the solution lets you monitor and optimize devices and apply best practices."

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

"I would rate the overall solution ten points out of ten."

"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"I like the way the solution sends alerts and how it keeps on escalating them."

"Nagios Core is very configurable. Whatever you want, you can do it."

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

"Dashboard provides monitor of total assets."

Cons

"What I want to improve in IDERA Uptime Infrastructure Monitor is the community aspect, where IDERA would provide customers with updates on functionalities, what comes next, what IDERA Uptime Infrastructure Monitor upgrades would be released, etc. I also want the sustainability of IDERA Uptime Infrastructure Monitor to improve."

"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 mapping is a little hard."

"The initial setup process could be easier."

"Nagios Core does not have a graphic display."

"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."

"The tool needs to improve the integrations."

"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."

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

More Nagios Core cons

Pricing and Cost Advice

"I'm based in Nigeria, and the conversion rate affects the pricing for IDERA Uptime Infrastructure Monitor, but globally, pricing is reasonable. I'm rating pricing for the solution seven on a scale of one to ten."

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

"The enterprise version has technical support. The version we are using is free."

"Lessening the price point would be an improvement."

"It's free."

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

"We are using the free version."

"Most the plugin features are free."

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