"Hardware health" monitoring is unreliable

"Hardware health" monitoring is unreliable

I have a Cisco 2821 router, which is reporting a fan failure on Fan #1. OpManager is showing all fans as healthy.

The router is reporting this:
149397: Jun  6 09:38:01.041 EDT: %ENVMON-3-FAN_FAILED: Fan 1 not rotating

Obviously I can't trust OpManager to report hardware health and I'm going to need to manually check all my equipment now.


This is the page for that router:
