https://community.splunk.com/t5/Reporting/How-can-I-produce-long-term-trend-reports/m-p/229063#M4701 <P>I work on a system which only has the capacity to retain data for 30 days. Once a week we produce a report which aggregates the data by a couple of dimensions. We would like to be able to produce long-term trend reports on that aggregated data (i.e. over multiple years). What is the best way to do that?</P> Tue, 04 Oct 2016 10:09:13 GMT jim_cross 2016-10-04T10:09:13Z https://community.splunk.com/t5/Reporting/How-can-I-produce-long-term-trend-reports/m-p/229063#M4701 <P>I work on a system which only has the capacity to retain data for 30 days.
