This section describes the configuration options you need to change. + +Let's assume you have the index pattern `customname-%{event.module}` where +`event.module` can have the values `system` and `apache`. First you must set up +a rollover index for `customname-system` and `customname-apache`. For details on +how to do this, see +{ref}/indices-rollover-index.html#_using_date_math_with_the_rollover_api[Rollover +Index]. + +Next, set the index pattern in the {es} output.
