Senior System Administrator at Interactive Group
Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

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.

Quotes from Members

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

Pros

"The reporting structure and the feature set are valuable to me."
"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."
"We use the product to monitor server applications."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"Nagios Core is stable."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The technical support team at Netreo is pretty good."
 

Cons

"I like to have the option to configure Nagios using the web interface."
"It is a bit slow due to latency."
"The user interface could be more interactive because it is pretty basic."
"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 and monitoring features could be improved."
"The interface could be improved."
"Default interface is clunky and slow."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"The scalability of Netreo is lacking."
