• Get the earliest sample ID for the specified day.  All data samples collected prior to this day will be deleted.  Replace DATE below with your target date in the format YYYY-MM-DD:

  Code Block
  language sql
  select min(id) from performance_sample where CONVERT(CHAR(10),sample_time,120) = 'DATE';

• Use the ID from the previous command in place of ID in the following commands.  It is strongly recommended that deletions be completed in small chunks (e.g. 2 weeks or 1 month at a time) rather than attempting one large delete statement.
  
  

  Code Block
  language sql
  delete from performance_aggregate where sample_id <ID; go;  delete from performance_cpu where sample_id <ID; go;  delete from performance_disk where sample_id <ID; go;  delete from performance_disk_total where sample_id <ID; go; delete from performance_esx3_workload where sample_id <ID; go;  delete from performance_fscap where sample_id <ID; go;  delete from performance_network where sample_id <ID; go;  delete from performance_nrm where sample_id <ID; go;  delete from performance_psinfo where sample_id <ID; go;  delete from performance_lpar_workload where sample_id <ID; go;  delete from performance_vxvol where sample_id <ID; go;  delete from performance_who where sample_id <ID; go;
