# Event field mapping configuration

# Event field mapping configuration {#ariaid-title1}

Use Event field mappings rules to map values from specific fields to values in other
fields.
Event Management stores event
field mappings in the Event Field Mapping \[em_mapping_rule\] table. The mappings
apply after event rule processing and prior to alert generation. The mapping values
from the Event Mapping Pair \[em_mapping_pair\] table apply to the alert. The original
event severity remains unchanged.

For example, if events come with the field "org_severity" with the values "Low, Medium, High" and you want the alert
Severity to hold this value, create an event field mapping rule that maps the field org_severity to Severity, with these values:  
{#c_EMEventFieldMapping__table_grj_13h_bcb__entry__2}

| Original org_severity value | Map to alert Severity value |
|-|-|
| Low | Warning |
| Medium | Major |
| High | Critical |
[Table 1. Example showing org_severity mapped to Severity]

{#c_EMEventFieldMapping__table_grj_13h_bcb}

## Default event field mappings {#c_EMEventFieldMapping__section_cfp_13h_bcb}

Event Management provides default event field mappings for commonly used
system monitoring tools. The Transform Value Pairs from event field mappings format
the incoming event data for Event Management.

You can view the default event field mappings and mapping pairs by navigating to Event ManagementRulesEvent Field Mappings and double-clicking Name.

  Use event field mappings to map values from specific event fields to values in other fields to provide more comprehensive information in an alert. Use team-based integrations in event rules to make sure that connector ownership and execution of rules give precedence to global rules. Teams can maintain consistency and hierarchy while offering flexibility and customization options.
