Hello,
What version of SolarWinds NPM are you running?
One workaround we have used is as follows:
On each polling engine change the SNMP polling from ENTITY-SENSOR MIB to ENVMON MIB:
c:\Program Files
(x86)\SolarWinds\Orion\HardwareHealth\SolarWinds.HardwareHealth.Pollers.dll.config,
change the
<add key="IgnoreCiscoNewEntityMib" value="false"/>
to
<add key="IgnoreCiscoNewEntityMib" value="true"/>
after this change (and restarting all services), the only OIDs polled will be those from CISCO-ENVMON-MIB.
Alternatively if you try an SNMPWALK on the OID for the hardware data and you find that it is also incorrect then you are seeing this Cisco bug: https://tools.cisco.com/bugsearch/bug/CSCul60923
