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

"We mostly use Nagios Core to integrate with Python and Bash Script."

"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."

"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."

"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 doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."

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

"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."

"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."

More Nagios Core pros

"Visual TruView helped our network team respond to potential issues before they became larger ones."

"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."

"It gives us the ability to determine the root of a problem or a network, whether it's on the network side, the database, application server, or server infrastructure."

"TruView takes only minutes to install."

"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

"The tool needs to improve the integrations."

"The mapping is a little hard."

"Lessening the price point would be an improvement."

"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."

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

"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."

"This is the open source product, so it's a toolkit rather than a complete solution."

"Generally, it does what I need it to do, but better error reporting would be great."

More Nagios Core cons

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

"I can't give them quite a 10, because from time to time, I'll work with the folks who, not that they're not good, but there are some who are just phenomenal."

"Whilst Citrix could be handled better like their nGenius product line (which does an excellent job) it copes with the centralised type of deployment TruView covers."

"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."

Pricing and Cost Advice

"Most the plugin features are free."

"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."

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

"The solution is expensive."

"Nagios Core is a cheap solution."

"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."
