 - disabled - (default: false) disables tracking and reporting of internal traces and spans
 - alwaysCreateGlobalIds - If true, assign newly created global ID to any requests that do not supply one.
 - optAlwaysCreateTraceIds - If true components generate trace/span ids if none are provided by the remote caller.
-- exporter - Defines The type of exporter in charge of forwarding span data to target back-end
-  - type - (default: JLOG) "OTLP-HTTP" | "OTLP-GRPC" | "OS" | "JLOG" | "NONE"
-  - JLOG
-    - logSpanDetails - Log span details such as description, status, kind
-    - logParentInfo  - Log the span's parent info such as ParentSpanId, and TraceState
-    - logAttributes  - Log the span's attributes
-    - logEvents      - Log the span's events
-    - logLinks       - Log the span's links
-    - logResources   - Log the span's resources such as telemetry.sdk version, name, language

-  - OTLP-GRPC
-    - endpoint: (default localhost:4317) The endpoint to export to. By default the OpenTelemetry Collector's default endpoint.

 ### Sample configuration
 Below is a sample helm values block directing the HPCC tracing framework to process span information serially, and export the data over OTLP/HTTP protocol to localhost:4318 and output export debug information to console:
 
 ```console
 global:
   tracing:
-    exporter:
-      type: OTLP-HTTP
+    exporters:
+    - type: OTLP-HTTP
       consoleDebug: true
-    processor:
-      type: simple
 ```
