If you check the gcagent.log, usually under <AGENT_INST>/sysman/log directory,  you will see messages as follows in the agent log gcagent.log:

WARN - oracle_ibswitch:xyx01sw-iba0.####.com:Sensors:AggregateSensors
oracle.sysman.emSDK.agent.fetchlet.exception.FetchletException: Can't get query descriptor or execution descriptor

WARN - oracle_ibswitch:xyz01sw-iba0.####.com:Sensors:VoltageSensors
