Field descriptions for the Observability data mapping form. Use this form to map activated services in Service Observability to metrics from your application performance monitoring (APM) instance. Each service can be mapped only once, but can contain exceptions to include all related entities.

Field Description
Mapping name Name for the mapping. The name should be descriptive so that users understand where the data is coming from.
Services Service to use for this mapping. Each service can be mapped only once.

For version 1.5.0 of Service Observability, services must be activated to be mapped. To activate a service, see Activate teams and services.
Default

where source tag key Tag key that you want to map to the activated service. If you use more than one tag to represent a service, you can create an exception. For example, most tags use service_name except for database metrics, which use service.
source tag value Value that represents the service name. Values can be strings or a variable that represents fields on the CI for the service. You can use variables on your APM data as the value to map multiple entities at once. For example, if your APM data uses the $service_name variable and you enter that as the source tag value, all services using that value are mapped.
Exceptions
