overwite of logging data

[Bsa_syslog]

Hi all

How/where do I set inside splunk so that the logging data(ie syslog data) can be overwrite in X number of months?

Anyone can advise? Thank in advance.

Or automatically delete away logging data in past X number of months also can.

Please help. Thanks.
