# 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 name
|
|
* `endTime`: End time of the entire trace in International Organization for Standardization (ISO) 8601 format
|
|
* `durationInNanos`: Duration of the entire trace in nanoseconds
|
|
* `statusCode`: 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](https://github.com/opensearch-project/data-prepper/blob/main/data-prepper-api/src/main/java/org/opensearch/dataprepper/model/processor/AbstractProcessor.java) 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. |
