otel_trace
The otel_trace processor completes trace-group-related fields in all incoming Data Prepper span records by state caching the root span information for each tradeId.
Parameters
This processor includes the following parameters.
traceGroup: Root span nameendTime: End time of the entire trace in International Organization for Standardization (ISO) 8601 formatdurationInNanos: Duration of the entire trace in nanosecondsstatusCode: Status code for the entire trace in nanoseconds
Configuration
The following table describes the options you can use to configure the otel_trace processor.
| Option | Required | Type | Description |
|---|---|---|---|
| trace_flush_interval | No | Integer | Represents the time interval in seconds to flush all the descendant spans without any root span. Default is 180. |
Metrics
The following table describes common Abstract processor metrics.
| Metric name | Type | Description |
|---|---|---|
recordsIn | Counter | Metric representing the ingress of records to a pipeline component. |
recordsOut | Counter | Metric representing the egress of records from a pipeline component. |
timeElapsed | Timer | Metric representing the time elapsed during execution of a pipeline component. |
The otel_trace processor includes the following custom metrics:
traceGroupCacheCount: The number of trace groups in the trace group cache.spanSetCount: The number of span sets in the span set collection.
