I recreated your issue in my environment and this is the solution that worked for me. The VPX_JOB_LOG table on my VCDB database is dbo.VPX_JOB_LOG. So I changed the sql for job_dbm_performance_data_mssql.sql from :
IF (SELECTCOUNT(*)FROMVPX_JOB_LOG WHERE ....
to this:
IF (SELECTCOUNT(*)FROM VCDB.dbo.VPX_JOB_LOG WHERE ...
and it worked just fine.
