Sorry about this, I know I've seen something similar before but I can't find it now.
I am monitoring the Fan RPM on one of our Dell Servers thanks to the SNMP check and Dell OpenManage.
My problem is with the warning thresholds. I'm getting a critical message because the critical level (1500 rpm) is lower than the operating RPM (4500 rpm). I've expressed -c as 0000:2999 and -w as 3000:4000 but thats not working either.
Any ideas ?
