We can only show you what the device gives to us. There's really almost zero scope for us to show you the wrong number, since we just show you whatever the device gave us, occasionally multiplied or divided by something depending upon the units used.
./poller.php -h <device_id> -m sensors
Find the SNMP query that collects the data for that sensor. It'll be returning the wrong data.
This is what's in the snmpwalk for that OID :
.1.3.6.1.4.1.9.9.117.1.1.1.1.4.470 = INTEGER: 6000
.1.3.6.1.4.1.9.9.117.1.1.1.1.4.471 = INTEGER: 5300
The units are defined here :
.1.3.6.1.4.1.9.9.117.1.1.1.1.2.470 = Hex-STRING: 43 65 6E 74 69 41 6D 70 73 20 40 20 31 32 56
.1.3.6.1.4.1.9.9.117.1.1.1.1.2.471 = Hex-STRING: 43 65 6E 74 69 41 6D 70 73 20 40 20 31 32 56
The HEX translates as "CentiAmps @ 12V"
So this is 6000 centiamps, or 60A
Nexus has always been really bug ridden when it comes to monitoring, and Cisco's QA sadly stopped existing 10 years ago.
