In device studio, the test node being built for a new custom poller is returning four usage values for the CPU (one for each CPU core). If the goal is to have one value for the entire CPU, how can that be accomplished?
A universal device poller (UDP) is being built for a metric to monitor in a radial gauge of a web console. When a gauge resource in the poller is to be selected, it is found that the resource is grayed out. What could be causing this?
