Hello, I am trying to delete data from _audit index. Currently it contains last 6 years data and occupying lot of space. I modified the $SPLUNK_HOME/etc/system/default/indexes.conf and added below under _audit stanza:
FrozenTimePeriodInSecs = 3153600
I restarted the splunk after making the changes. But I still see older data under Audit. Can you please help in finding what is wrong here? Do I need to make any additional changes or invoke anything to reflect the changes?
