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 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."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"The most valuable feature is the performance parameters of the system."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"The technical support team at Netreo is pretty good."
 

Cons

"Lessening the price point would be an improvement."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"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."
"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."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The scalability of Netreo is lacking."
 

Pricing and Cost Advice

"We are using the free version of Nagios Core."
"It's free."
"The product is cheaply priced."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

Questions from the Community

What is your experience regarding pricing and costs for Nagios Core?
Nagios Core is a free and open-source product. We don't charge for the product itself, but we charge for the man-hour costs related to installation, configuration, ongoing operation, and maintenance.
