 - Metrics with the `_created` suffix are automatically generated by Prometheus for counters and gauges to track when they were first created.
 - The `rdi_incoming_entries` metric provides a detailed breakdown for each data source by operation type.
 - The `rdi_stream_event_latency_ms` metric helps monitor data freshness and processing delays.
+- The `rdi_processor_performance_batch_avg` metric provides detailed performance insights.
