Send Traces from Phoenix -> Arize

You can use Phoenix to collect traces, run evals, and perform data modifications in a notebook environment until you're ready to export data to Arize using our Python SDK.

This guide details how to collect traces in Phoenix and send them to Arize.

Collect Traces in Phoenix

Enable Phoenix tracing is very similar to what we showed in the section above since it also leverages the OpenInference instrumentation. For more details, see the Phoenix Quickstart Guide to Tracing.

Your application traces should stream into the Phoenix UI as shown below

Send data to Arize

When you're ready to send your data to Arize, run the following command to export your traces from Phoenix.

spans_df = px.Client().get_spans_dataframe()

This command creates a dataframe object as shown below:

The dataframe can be directly sent to Arize using our Python SDK. Schema mapping is not required for OpenInference traces since Arize will automatically understand the column names from your dataframe.

To send tracing data via the Python SDK, it must be installed with extra dependencies

pip install arize[Tracing]

(Cloud import support coming soon)

The following code example shows how to send a dataframe with traces exported from Phoenix to Arize via the log_spans method. Note that we do not need to specify any Schema.


    raise ValueError("❌ NEED TO CHANGE SPACE AND/OR API_KEY")
    print("✅ Import and Setup Arize Client Done! Now we can start using Arize!")
arize_client = Client(space_key=SPACE_KEY, api_key=API_KEY)
model_id = "generative-spans-tutorial-test" # the model name in Arize
model_version = "1.0" # (optional) the model version

response = arize_client.log_spans(
    model_version=model_version, # optional

# If successful, the server will return a status_code of 200
if response.status_code != 200:
    print(f"❌ logging failed with response code {response.status_code}, {response.text}")
    print(f"✅ You have successfully logged training set to Arize")
