[Xen-users] Snmp CpuRawIdle showing double?

[Nathan March <nathan@xxxxxxxxxxxxxxxxxxxx>]

 Having a strange issue where snmp polling a vm for the ssCpuRawIdle 
stats (and all the other raw cpu stats) shows up as double:
snmpwalk -v 2c -c 'XXXX' nathanxen1 1.3.6.1.4.1.2021.11.53 && sleep 60 
&& snmpwalk -v 2c -c 'XXXXXXX' nathanxen1 1.3.6.1.4.1.2021.11.53
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 47631385
UCD-SNMP-MIB::ssCpuRawIdle.0 = Counter32: 47643353

(47643353 - 47631385) / 6000 * 100 = 199%

Except that this VM has a single cpu. Polling regular machines works 
fine with this logic and returns the expected numbers.
