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

"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."

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

"Provides timely notifications."

"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 solution is very complete and mostly easy to manage."

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

"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

More Nagios Core pros

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

"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."

"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."

"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

"They should simplify the features so it becomes easier to setup out of the box."

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."

"Nagios Core does not have a graphic display."

"I would like to see more training videos."

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

"It is a bit slow due to latency."

"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

More Nagios Core cons

"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."

"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."

"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

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

"Most the plugin features are free."

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

"Nagios Core is free to use."

"It's free."

"The product is cheaply priced."

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

"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."
