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.
