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.

More Nagios Core pros

More WhatsUp Gold pros

Cons

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

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

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

"The tool needs to improve the integrations."

"The initial setup process could be easier."

"The scalability needs improvement, it's not scalable at this time."

"The interface could be improved."

More Nagios Core cons

"Pricing is too high relative to how many devices we use. The price list is not linear to number of devices."

"Regional product team support is not very good."

"There are some subscription charges that are quite heavy. I need to pay for support every year and these charges can be quite expensive."

"I haven't had any issue with stability, except during the upgrade to 2017 when we encountered slow responses."

"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."
