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 application performance monitoring feature is valuable."

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

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"I like the way the solution sends alerts and how it keeps on escalating them."

"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."

"Nagios Core is very configurable. Whatever you want, you can do it."

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

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

More Nagios Core pros

"WhatsUp Gold is very easy to deploy."

"The best feature of WhatsUp Gold is the automatic generation of topology and its integration with virtualization and wireless."

"The product is reasonably priced."

"The most valuable features are network bandwidth monitoring and monitoring device health."

"The user interface is good enough."

"I use it on premises to monitor my network database. We monitor the link up/down and use the SNMP traps as well."

"The most valuable feature is the auto-discovery function."

"NetFlow monitoring, real-time monitoring, and surveys have been the most valuable features for our business."

More WhatsUp Gold pros

Cons

"The core version is no match for the XI version."

"I would like to see more training videos."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"The mapping is a little hard."

"The dashboard should be improved."

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

"The interface could be improved."

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

More Nagios Core cons

"The product is old and not updated."

"The pricing for this solution has gone up quite recently, which has led some of our customers to buy an alternative product."

"Improvements are needed in integration, especially for WhatsApp call and messages. Our region heavily uses WhatsApp Messenger for communication, and integration with this platform would be beneficial."

"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."

"I think there are a few bugs now. Although they give some resolution for this, we cannot share the network remotely because of our company policy."

"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."

"The point system is not clear and clarity around this would improve our understanding of the system."

"I would like to see better integration with switches so that you can see what is connected to each port, what the traffic is, and have a network map automatically generated."

More WhatsUp Gold cons
