Monitors traffic, analyzes flows, tracks packets, and measures bandwidth across our network

We use TruView primarily for network performance analysis and monitoring. It helps us track traffic, flows, packets, and bandwidth to understand our network's condition and detect any anomalies or attacks. However, the product's age limits its advanced features for performance analysis. The main advantage lies in its low cost and reliable functionality, as we have a permanent license and do not require support. Real-time monitoring in TruView is somewhat limited, as there is a delay of about five minutes in data updates, making it less effective for immediate insights.

Quotes from Members

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

Pros

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"The most valuable feature is the performance parameters of the system."

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"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."

"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 good thing about Nagios Core is it covers everything."

"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."

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

"We use TruView primarily for network performance analysis and monitoring.

Real-time monitoring in TruView is somewhat limited, as there is a delay of about five minutes in data updates, making it less effective for immediate insights."

"The most valuable feature for us was the ability to monitor sites and get a nice overview of all the data in a single view."

Cons

"t was a little hard to get our setup represented in the configuration."

"Nagios Core does not have a graphic display."

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

"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."

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

"The interface could be improved."

"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 alerting mechanism in Nagios Core could be improved."

More Nagios Core cons

"One area that could be improved is the reporting features. In the version transformation from ten to eleven, the platform changed from a Windows-based platform to a Linux-based platform. As a result, the previous reporting feature using Crystal Reports was no longer available. Instead, we had to generate PDF dashboard reports, which were not as flexible."

"We have faced delays in data retrieval and the lack of support due to the product being out of service."

Pricing and Cost Advice

"The solution is expensive."

"Nagios Core is free to use."

"It's free."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"Nagios Core is an open source solution, and there are no licensing fees."

"The enterprise version has technical support. The version we are using is free."

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

"We are using the free version."
