Recently we connected a new PoE-capable time clock to one of our closet switches, and because we've learned to take advantage of electricity, I failed to verify the switch had enough juice for the clock. And the fact is, it didn't have enough. So, I started thinking about other switches that may be close to capacity, and realized some of the NPM EnergyWise components could be enhanced.
- Device Power Consumption resource - tells a great story of how much power the device is using, but the real story is:
- How much is the device using versus how much are the connected devices using
Is there a way to build a table that looks similar to the output of "show power inline"?

And also have the ability to alert on devices that are close to capacity (based on a threshold setting). Of course, creating reports is also something I'd like to be able to do with this data.
