KEEP_ISI_LOG_MONTHS
Daily data that is older than the last 6 months (defined in the system parameter KEEP_ISI_LOG_MONTHS) is purged as a normal process. This process is scheduled for the Monday after the 15th of every month at 7:00 a.m.
Example of Customizing the EMC Isilon Performance Data:
When you modify the KEEP_ISI_LOG_MONTHS parameter, you are changing the purge interval for all Isilon performance tables.
update ptl_system_parameter set param_value = ‘4’
where param_name = 'KEEP_ISI_LOG_MONTHS’;
