# Health Log Analytics severity mapping

Health Log Analytics (HLA) uses common severity values to identify severity labels in the Source Type Structure.
The Log severity mapping table illustrates how HLA identifies severity words from raw logs (shown in the left column), maps them to its own severity values (middle column), and then presents them in Event Management alerts (right column).

Note:  
If your raw log contains numerical severities or unrecognized words, map these values to the HLA Log Severity column by creating a conditional statement using the JS function in the Source Type Structure. For more information, see [Source type structure adjustment](https://servicenow-prod.fluidtopics.net/QrL5WXM7uUk9ET5jegVJAw "Health Log Analytics enables you to reclassify auto-classified properties and change auto-mapped labels. These adjustments help Health Log Analytics machine learning to better understand your priorities.").
