No data being shown in the Performance Analysis for SQL Server Overview screen, why? Version of Performance Analysis for SQL Server installed is 7.0.310.
This is caused by the fact that PASS7.0.310 does not support SQL Server version 10.0.2734 or SQL Server version 10.0.2766.
Please upgrade the Middleware first and then the Monitored host with the version under ftp://support:email@example.com/Dbtool/download/PS/STEALTH/PA_7.0/Patches/PASS/LSI_PASS7.0_Win_x64_10.0.2850/. If further issues are seen, then please raise a case with our support team.
