Enum Class BlobTransferOtelMetricEntity

java.lang.Object

java.lang.Enum<BlobTransferOtelMetricEntity>

com.linkedin.davinci.stats.BlobTransferOtelMetricEntity

All Implemented Interfaces:

ModuleMetricEntityInterface, Serializable, Comparable<BlobTransferOtelMetricEntity>, Constable

public enum BlobTransferOtelMetricEntity
extends Enum<BlobTransferOtelMetricEntity>
implements ModuleMetricEntityInterface

OTel metric entities for blob transfer operations.

Maps blob transfer telemetry into OTel metrics:

• source-specific request outcomes → 1 COUNTER with source and response-status dimensions
• Version-topic fallbacks → 1 COUNTER with a blob_transfer.fallback_reason dimension
• 3 count sensors (total/success/fail) → 1 COUNTER with response_status_category dimension
• throughput gauge → dropped (derivable as rate from bytes.received)
• time gauge → 1 HISTOGRAM in seconds
• bytes received rate gauge → 1 COUNTER in bytes
• bytes sent rate gauge → 1 COUNTER in bytes
