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.

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

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

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

"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 the product to monitor server applications."

"The solution's most valuable feature is that it offers proper alerting capabilities."

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

"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."

"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

"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."

"It is a bit slow due to latency."

"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."

"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."

"Would benefit from aggregations if a particular server goes down."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."

"The dashboard and monitoring features 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

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

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

"Most the plugin features are free."

"Nagios Core is free to use."

"The product is cheaply priced."

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

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

"The solution is expensive."
