# arize-phoenix-otel
Provides a lightweight wrapper around OpenTelemetry primitives with Phoenix-aware defaults.
These defaults are aware of environment variables you may have set to configure Phoenix:
- `PHOENIX_COLLECTOR_ENDPOINT`
- `PHOENIX_PROJECT_NAME`
- `PHOENIX_CLIENT_HEADERS`
- `PHOENIX_API_KEY`
# Examples
The `phoenix.otel` module provides a high-level `register` function to configure OpenTelemetry
tracing by setting a global `TracerProvider`. The register function can also configure headers
and whether or not to process spans one by one or by batch.
## Quickstart
```
from phoenix.otel import register
tracer_provider = register()
```
This is all you need to get started using OTel with Phoenix! `register` defaults to sending spans
to an endpoint at `http://localhost` using gRPC.
## Phoenix Authentication
If the `PHOENIX_API_KEY` environment variable is set, `register` will automatically add an
`authorization` header to each span payload.
### Configuring the collector endpoint
There are two ways to configure the collector endpoint:
- Using environment variables
- Using the `endpoint` keyword argument
#### Using environment variables
If you're setting the `PHOENIX_COLLECTOR_ENDPOINT` environment variable, `register` will
automatically try to send spans to your Phoenix server using gRPC.
```
# export PHOENIX_COLLECTOR_ENDPOINT=https://your-phoenix.com:6006
from phoenix.otel import register
tracer_provider = register()
```
#### Specifying the `endpoint` directly
When passing in the `endpoint` argument, **you must specify the fully qualified endpoint**. For
example, in order to export spans via HTTP to localhost, use Pheonix's HTTP collector endpoint:
`http://localhost:6006/v1/traces`. The gRPC endpoint is different: `http://localhost:4317`.
```
from phoenix.otel import register
tracer_provider = register(endpoint="http://localhost:6006/v1/traces")
```
### Additional configuration
`register` can be configured with different keyword arguments:
- `project_name`: The Phoenix project name (or `PHOENIX_PROJECT_NAME` env. var)
- `headers`: Headers to send along with each span payload (or `PHOENIX_CLIENT_HEADERS` env. var)
- `batch`: Whether or not to process spans in batch
```
from phoenix.otel import register
tracer_provider = register(
project_name="otel-test", headers={"Authorization": "Bearer TOKEN"}, batch=True
)
```
## A drop-in replacement for OTel primitives
For more granular tracing configuration, these wrappers can be used as drop-in replacements for
OTel primitives:
```
from opentelemetry import trace as trace_api
from phoenix.otel import HTTPSpanExporter, TracerProvider, SimpleSpanProcessor
tracer_provider = TracerProvider()
span_exporter = HTTPSpanExporter(endpoint="http://localhost:6006/v1/traces")
span_processor = SimpleSpanProcessor(span_exporter=span_exporter)
tracer_provider.add_span_processor(span_processor)
trace_api.set_tracer_provider(tracer_provider)
```
Wrappers have Phoenix-aware defaults to greatly simplify the OTel configuration process. A special
`endpoint` keyword argument can be passed to either a `TracerProvider`, `SimpleSpanProcessor` or
`BatchSpanProcessor` in order to automatically infer which `SpanExporter` to use to simplify setup.
### Using environment variables
```
# export PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006
from opentelemetry import trace as trace_api
from phoenix.otel import TracerProvider
tracer_provider = TracerProvider()
trace_api.set_tracer_provider(tracer_provider)
```
#### Specifying the `endpoint` directly
```
from opentelemetry import trace as trace_api
from phoenix.otel import TracerProvider
tracer_provider = TracerProvider(endpoint="http://localhost:4317")
trace_api.set_tracer_provider(tracer_provider)
```
### Further examples
Users can gradually add OTel components as desired:
## Configuring resources
```
# export PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006
from opentelemetry import trace as trace_api
from phoenix.otel import Resource, PROJECT_NAME, TracerProvider
tracer_provider = TracerProvider(resource=Resource({PROJECT_NAME: "my-project"}))
trace_api.set_tracer_provider(tracer_provider)
```
## Using a BatchSpanProcessor
```
# export PHOENIX_COLLECTOR_ENDPOINT=http://localhost:6006
from opentelemetry import trace as trace_api
from phoenix.otel import TracerProvider, BatchSpanProcessor
tracer_provider = TracerProvider()
batch_processor = BatchSpanProcessor()
tracer_provider.add_span_processor(batch_processor)
```
## Specifying a custom GRPC endpoint
```
from opentelemetry import trace as trace_api
from phoenix.otel import TracerProvider, BatchSpanProcessor, GRPCSpanExporter
tracer_provider = TracerProvider()
batch_processor = BatchSpanProcessor(
span_exporter=GRPCSpanExporter(endpoint="http://custom-endpoint.com:6789")
)
tracer_provider.add_span_processor(batch_processor)
```
