Provides a stable solution but would improve by developing an all-in-one-solution

The advice I would give to anyone looking at implementing Netreo into their organization would be to do your market research and evaluate the product, do not just choose it because someone recommends it to you. Overall, from my perspective, I would rate the solution a seven out of ten.

"I like to have the option to configure Nagios using the web interface."

"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."

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

"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."

Pricing and Cost Advice

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