`otel_apm_service_map` processor analyzes OpenTelemetry trace spans to automatically generate Application Performance Monitoring (APM) service map relationships and metrics. It creates structured events that can be visualized as service topology graphs, showing how services communicate with each other and their performance characteristics. + +## Key Features + +- **Service Relationship Discovery**: Automatically identifies service-to-service connections from OpenTelemetry spans +- **APM Metrics Generation**: Creates latency, throughput, and error rate metrics for service interactions +- **Three-Window Processing**: Uses sliding time windows to ensure complete trace context +- **Environment-Aware**: Supports service environment grouping and custom attributes +- **Off-Heap Storage**: Efficient memory usage with MapDB for large-scale processing +- **Real-Time Processing**: Generates service map data as traces are processed + +## How It Works + +### Three-Window Sliding Architecture + +The processor uses three overlapping time windows to ensure complete trace processing: + +- **Previous Window**: Completed spans from the previous time period +- **Current Window**: Spans being actively processed +- **Next Window**: Incoming spans for the next time period + +This approach ensures that spans from long-running traces that cross window boundaries are properly correlated. + +### Two-Phase Processing + +#### Phase 1: Span Decoration +1. **CLIENT Span Processing**: Identifies outbound service calls and decorates them with remote service information +2. **SERVER Span Processing**: Processes inbound requests and back-annotates related CLIENT spans + +#### Phase 2: Event Generation +1. **ServiceConnection Events**: Represents service-to-service relationships +2. **ServiceOperationDetail Events**: Represents specific operations within services +3. **Metrics Generation**: Creates aggregated performance metrics + +### Span Analysis + +The processor analyzes different span kinds: +- **CLIENT spans**: Represent outbound calls to other services +- **SERVER spans**: Represent inbound requests being processed +- **Span relationships**: Uses parent-child relationships to build complete call chains + +## Configuration + +### Basic Configuration + +```yaml +processor: + - otel_apm_service_map: + window_duration: 60 +

`request_rate` +- **Error metrics**: `error_count` and `error_rate` +- **Status code metrics**: HTTP status code distributions + +## Performance Considerations + +### Memory Usage + +- **Off-heap
