Health Log Analytics extracts source types automatically in the
mapping process. You can add timestamp formats and specify, delete, or exclude keywords for
individual source types.

## Before you begin

Role required: evt_mgmt_admin

## Procedure

1. Navigate to AllHealth Log AnalyticsData InputSource Types.  
   The Source Types table lists all source types that were extracted automatically during raw data mapping.  
   {#hla-source-types__table_hdc_xbx_l4b__entry__2}

   | Field | Description |
   |-|-|
   | Auto extraction enabled | Auto-extraction for this source type is either enabled or disabled. This value is set on the Source Type Structure form. Default: true. |
   | Learning mode | Learning mode for the source type is either ongoing or completed. The AI engine must learn the format of log messages in each new log stream. In Learning mode, it learns the format of messages for this source type and extracts properties based on that knowledge. |
   | Stack trace detection enabled | Detection of active stack frames for this source type is either enabled or disabled. Typically, a stack trace enables tracking an error to the log in which it originated. |
