Use Cases and Deployment Scope
We use Progress WhatsUp Gold in order to monitor everything from cpu, disk, memory to services and uptime. It allows us to have an agentless and vendor agnostic monitoring solution that can provide data to essentially any device with an ip address. They have quite a few built in monitors with the ability to query anything that is exposed via snmp or WMI.
