On a Linux system:
snmpwalk -v 2c -c public -M /usr/share/snmp/mibs/ -m ALL localhost sunHwMonSensorGroup | grep '\.9 = '
On an Oracle Solaris 11.1 system:
snmpwalk -v 2c -c public -M +/usr/lib/ssm_directory/lib/mibs/ -m ALL localhost sunHwMonSensorGroup | grep '\.9 = '
Where ssm_directory is either sun-ssm or ssm, depending on your version of Oracle Hardware Management Pack.
On an Oracle Solaris 10 system:
snmpwalk -v 2c -c public -M +/opt/ssm_directory/lib/mibs/ -m ALL localhost sunHwMonSensorGroup | grep '\.9 = '
Where ssm_directory is either sun-ssm or ssm, depending on your version of Oracle Hardware Management Pack.
where grep '\.9 = ' is filtering a property of the FRU we are interested in.
