I have to trim ITSI KV store collection size. I have created a local itsi_notable_event_retention.conf file in $SPLUNK_HOME/etc/apps/SA-ITOA/local/. I override the default values of retentionTimeInSec to 3 months. However the no of objects in the collection are still growing and hence the collection size. How do I trim the collection size? I followed this document Modify notable event KV store collections in ITSI - Splunk Documentation. Please assist.
