Senior Systems Administrator, Technical Lead at Connectivity Wireless
A network monitoring platform with a useful reporting feature, but permission-based options could be better
The initial setup is fairly easy. Most of it's wizard-based. You don't have to be a rocket scientist to set it up. But if you don't know certain things related to protocols and everything else, it might be difficult. If you know how SNMP works, it'll be fairly simple to set up.

Scientist at a educational organization with 10,001+ employees
A mature and affordable solution that is easy to install and easy to update
The product takes time to learn, it's not that easy. In the beginning we had a lot of questions. If you want to use such a tool in an real (industrial) environment, you have to ask how to get the network data. Can we do a full packet capture? Can we provide agents to our end systems? There are no simple solutions to these questions. It's a general problem when running such systems in an industrial environment.
