Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Efficient monitoring with detailed customization, yet complexity remains
The best feature of WhatsUp Gold is the automatic generation of topology and its integration with virtualization and wireless. I have used the automated device discovery with this topology feature. The interactive map feature helps me manage the topology because sometimes we cannot draw the topology correctly, so we need to manually edit the connections. The alerting system is very tunable and customizable, but it's a little complicated to use. Many customers cannot manage it by themselves and need support from us, the provider. We always use the dashboards in the SOC, where we constantly display a dashboard or multiple dashboards. This allows us to know immediately if the connection or bandwidth is full or if the connection is broken.

Quotes from Members

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

Pros

"The most useful aspect of this solution is the ability to customize it for the client agent."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Nagios XI helped me to draw the network and check for system failures."
"I can monitor a software made in-house to software of bigger companies."
"It is an open-source platform with valuable features for performance and stability."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The solution is pretty stable."
"NetFlow monitoring, real-time monitoring, and surveys have been the most valuable features for our business."
"The best feature of WhatsUp Gold is the automatic generation of topology and its integration with virtualization and wireless."
"We no longer have to manually search for problems because we are alerted when something in the network goes down."
"Our local support team provides excellent service."
"The most valuable feature is the auto-discovery function."
"Auto scanning is most valuable. It looks for rogue devices on your network."
"The most valuable feature of WhatsUp Gold is NetFlow and the virtualized maps."
"This is a good, stable network monitoring solution for devices."
 

Cons

"The reporting structure could be more streamlined."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"The product's stability could be even better."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"The product is old and not updated."
"Regional product team support is not very good."
"I would like to see them do an enhancement to the application monitoring. A lot of other products do better application monitoring so they should do some improvements to the application monitoring."
"WhatsUp Gold should work on real-time monitoring and configuration management. If they succeed in doing this, the solution will cover all the network troubleshooting aspects and will be a benefit."
"The interface needs some work."
"The new release cadence needs to be improved. It takes a while for them to add new features and functionality. There should be a quicker turnaround with new versions."
"The tool should focus on increasing its market share, as it is the only area of concern where improvements are needed."
"Setting up WhatsUp Gold is complicated and not easy because it requires managing SNMP and many complex settings in the devices it's monitoring, and fine-tuning it to fit our needs is also not very easy."
 

Pricing and Cost Advice

"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The licensing fees for this solution are approximately $3,000 USD per year."
"We are using the free version of this solution."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"Nagios XI is open source."
"There is a license needed to use WhatsUp Gold."
"The tool's price is reasonable. WhatsUp Gold is cheaper than SolarWinds."
"It is per device, per year. The pricing is very clear. If you have a service agreement, you get all of your major upgrades and minor upgrades. It was under $10,000 to go all-in with all of the different add-ons for it."
"The choice of version depends on the number of points, or devices, that you want to monitor, and this makes the product expensive."
"The price of WhatsUp Gold is good."
"This is a well priced solution."
"I'm not sure, but it's expensive. We don't pay any additional fees."
"The most valuable feature is the cost compared to other solutions."
