Valuable reporting and alert system with room for PDF export improvements

The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

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

"Dashboard provides monitor of total assets."

"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."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"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."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"It is fairly easy to set up, and we can monitor pretty much everything we want to."

"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."

"We use the product to monitor server applications."

More Nagios Core pros

"The technical support team at Netreo is pretty good."

Cons

"Nagios Core can improve the graphical interface, it would make things a little easier."

"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 mapping is a little hard."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

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

"The core version is no match for the XI version."

"The user interface could be more interactive because it is pretty basic."

"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."

More Nagios Core cons

"The scalability of Netreo is lacking."

Pricing and Cost Advice

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

"Lessening the price point would be an improvement."

"It's free."

"Most the plugin features are free."

"We are using the free version."

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

"I would rate the solution's pricing an eight out of ten."

"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."

The dashboard should be improved. It's very simple. I don't have a very clear or specific suggestion. You can change the skin of the dashboard, however, it's good for me.
