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

"Nagios Core is stable."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"Its an awesome product to use."
"Extensibility is good as this makes it easy to write checks on your own."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
"The poller is really good, I can easily implement new stuff and it is scalable."
"The technical support team at Netreo is pretty good."
 

Cons

"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"They should simplify the features so it becomes easier to setup out of the box."
"The dashboard should be improved."
"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."
"Generally, it does what I need it to do, but better error reporting would be great."
"The mapping is a little hard."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"The scalability of Netreo is lacking."
 

Pricing and Cost Advice

"I would rate the solution's pricing an eight out of ten."
"Nagios Core is free to use."
"Nagios Core is a cheap solution."
"We are using the open-source, unpaid version."
"The product is cheaply priced."
"Lessening the price point would be an improvement."
"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."
"It's free."
