Cisco 9300-24T Hardware Monitoring (failed power supply) - Not working?

Chris-S

Considering the following output of a two switch stack:

x#show ver | in Model


Model Revision Number : A0
Model Number : C9300-24T

x#show env power all 
SW PID Serial# Status Sys Pwr PoE Pwr Watts
-- ------------------ ---------- --------------- ------- ------- -----
1A PWR-C1-350WAC-P xxxxxxxxxxxx No Input Power Bad Bad 350 
1B PWR-C1-350WAC-P xxxxxxxxxxxx OK Good Good 350 
2A PWR-C1-350WAC-P xxxxxxxxxxxx OK Good Good 350 
2B PWR-C1-350WAC-P xxxxxxxxxxxx OK Good Good 350

...I was surprised to find that Solarwinds did not detect the bad power supply.  The solarwinds NPM "node info widget" states (custom information edited out):

Normally a failed power supply, even one that is just unplugged, would show up as a failure that Solarwinds would flag.  Why is it not in this case?
