Gathering Hardware Utilization Statistics for UCS B/C Series via SNMP - Is it possible?

[asafayan]

It is possible to gather typical cpu, memory, fan speed, and hdd utilization statistics from the Cisco MIBs for UCS B / C series servers?

The excellent Cisco UCS Monitoring Resource Handbook (https://communities.cisco.com/docs/DOC-37197) provides a link to the following document for MIB Loading Order and Statistics Collection Details:

MIB Reference for Cisco UCS Standalone C-Series Servers:

http://www.cisco.com/en/US/docs/unified_computing/ucs/sw/mib/c-series/b_UCS_Standalone_C-Series_MIBRef.pdf

In Table Four of the above referenced document, it contains various MIBs/OIDs used for gathering statistics.
For example, this processor section:

Processor

CISCO-UNIFIED-COMPUTING-PROCESSOR-MIB .1.3.6.1.4.1.9.9.719.1.41 is the parent OID where the key statistics reside.

processorEnvStats—Provides all CPU power and temperature statistics for every CPU socket. processorUnit—Provides all CPU statistics for every CPU.

When walking the following C Series with the suggested OID:
snmpwalk -v2c -c XXXXXXX -m ALL XXXXXX sysdesc
SNMPv2-MIB::sysDescr.0 = STRING: Cisco Integrated Management Controller(CIMC) [UCS C220 M3S], Firmware Version 1.5(1l) Copyright (c) 2008-2012, Cisco Systems, Inc.
 

I get the following output:

Typical CPU performance graphs provide percentage integers in vertical or y-axis and time in the horizontal or x-axis. The suggested OID yields no percentage utilization which I can graph.   Am I correct in concluding that we must poll the hypervisor for this data instead of the CIMC directly?

Thanks,
