Create a source type manually before you configure a data input if you want to stream
log data to a specific source type rather than to the source type automatically extracted by
Health Log Analytics during the mapping process.

## Before you begin


This feature is supported in the Health Log Analytics application, Version 20.0.11 - July 2021, available from the [ServiceNow Store](https://store.servicenow.com/sn_appstore_store.do#!/store/home).

Role required: evt_mgmt_admin

## Procedure

1. Navigate to AllHealth Log AnalyticsData InputSource Types.
2. On the Source Types page, select New.
3. On the form, fill in the fields.  
   {#hla-source-types-manual__table_cwx_llc_lpb__entry__2}

   | Field | Description |
   |-|-|
   | Name | The name of the source type. The name must be between 3-50 characters long. Acceptable characters are letters, numeric values, dashes, and underscores. |
   | Examples | One or more raw input samples for this source type. Enter each sample on a new line. Note: This field must contain data. |
   [Table 1. Source type form]

   {#hla-source-types-manual__table_cwx_llc_lpb}

   The fields in the following table are read-only.  
   {#hla-source-types-manual__table_xnp_zpc_lpb__entry__2}

   | Field | Description |
   |-|-|
   | Created manually | Option for indicating that this source type was created manually. Default: true. |
   | Auto-extraction enabled | Auto-extraction for this source type is disabled by default. |
   | Learning mode | Option for indicating that Learning mode for the source type is ongoing. 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. |
   [ ]

   {#hla-source-types-manual__table_xnp_zpc_lpb}
4. Right-click the form header and select Save.
5. Select Load examples to load the raw input samples for this source type that you provided in the Examples field.  
   When loading the log samples is completed successfully, the Examples field and the Load examples buttons no longer appear on the form.
6. **Optional:** Check how the AI engine has parsed the raw input samples by selecting the Go to Source Type Structure related link and modify the extracted properties if necessary.
7. Click Submit.

## What to do next

Configure a data input and then map it to the new source type. For more information,
see [Set up data inputs for Health Log Analytics manually](https://servicenow-prod.fluidtopics.net/~9C8cvT1lkIgNfh78QVxGQ "Set up your Health Log Analytics data inputs for Health Log Analytics manually. Data input configuration is an essential step in setting up the Health Log Analytics application.") and [Map raw log data](https://servicenow-prod.fluidtopics.net/ENjBmAW1AM2qvvmJSA_YiQ "Mapping raw log data that streams into your instance determines how the data is handled. Health Log Analytics automatically structures logs, creates metrics for anomaly detection, and presents alerts based on how your data is tagged.").
