You can check the s_qos_data table and from there the rn_qos_data table can be queried to see data collected. Here are some examples on what to query.
select * FROM S_QOS_DATA where probe = 'cdm' and source = '10.1.1.100'
select * FROM S_QOS_DATA where qos = 'QOS_CPU_USAGE' and source = '10.1.1.100'
From that query two things are needed, the table_id & rn_data table.
select * FROM [CA_UIM].[dbo].[RN_QOS_DATA_0010] where table_id = 14
