These commands are permanent.  All deleted data will be lost.  Ensure that you complete a full data backup before proceeding with these commands.

 

It is strongly recommended that you use the stored procedure that accomplishes the same outcome as the statements below with less effort.  It is available by contacting Support at [email protected]

The following commands will delete all performance data prior to a specified date:

 

  • 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.
select min(id) from performance_sample where TO_CHAR(sample_time,'YYYY-MM-DD') - 'DATE';
  • Use the ID from the previous command in place of ID in the following commands.  It is strongly recommended that deletions are completed in small chunks (e.g. 2 weeks or 1 month at a time) rather than attempting one large delete statement.
delete from performance_aggregate where sample_id < ID; commit;
delete from performance_cpu where sample_id < ID; commit;
delete from performance_disk where sample_id < ID; commit;
delete from performance_disk_total where sample_id < ID; commit;
delete from performance_esx3_workload where sample_id < ID; commit;
delete from performance_fscap where sample_id < ID; commit;
delete from performance_lpar_workload where sample_id < ID; commit;
delete from performance_network where sample_id < ID; commit;
delete from performance_nrm where sample_id < ID; commit;
delete from performance_psinfo where sample_id < ID; commit;
delete from performance_vxvol where sample_id < ID; commit;
delete from performance_who where sample_id < ID; commit;
  • The process above needs to be repeated for the VMware performance tables.  Replace DATE below with the same target date as above in the format YYYY-MM-DD.
select min(id) from performance_sample where TO_CHAR(sample_time,'YYYY-MM-DD') - 'DATE';

 

  • Use the ID from the previous command in place of ID in the following commands. 
delete from vmware_perf_aggregate where sample_id < ID; commit;
delete from vmware_perf_cluster where sample_id < ID; commit;
delete from vmware_perf_datastore_usage where sample_id < ID; commit;
delete from vmware_perf_datastore_vm_usage where sample_id < ID; commit;
delete from vmware_perf_disk_rate where sample_id < ID; commit;
delete from vmware_perf_entitlement where sample_id < ID; commit;
delete from vmware_perf_host_cpu where sample_id < ID; commit;
delete from vmware_perf_host_disk_io where sample_id < ID; commit;
delete from vmware_perf_host_disk_io_adv where sample_id < ID; commit;
delete from vmware_perf_host_network where sample_id < ID; commit;
delete from vmware_perf_host_power_state where sample_id < ID; commit;
delete from vmware_perf_mem where sample_id < ID; commit;
delete from vmware_perf_mem_advanced where sample_id < ID; commit;
delete from vmware_perf_network_rate where sample_id < ID; commit;

delete from vmware_perf_vm_disk_io where sample_id < ID; commit;
delete from vmware_perf_vm_network where sample_id < ID; commit;
