Cloud Trace Exporter Example

These examples show how to use OpenTelemetry to send tracing data to Cloud Trace.

Basic Example

To use this exporter you first need to:
  • A Google Cloud project. You can create one here.
  • Enable Cloud Trace API (listed in the Cloud Console as Stackdriver Trace API) in the project here. * If the page says "API Enabled" then you're done! No need to do anything.
  • Enable Default Application Credentials by creating setting GOOGLE_APPLICATION_CREDENTIALS or by installing gcloud sdk and calling gcloud auth application-default login.
  • Installation
pip install opentelemetry-api
pip install opentelemetry-sdk
pip install opentelemetry-exporter-cloud-trace
  • Run an example locally
.. literalinclude:: basic_trace.py
    :language: python
    :lines: 1-

Checking Output

After running any of these examples, you can go to Cloud Trace overview to see the results.

Troubleshooting

Running basic_trace.py hangs:

  • Make sure you've setup Application Default Credentials. Either run gcloud auth application-default login or set the GOOGLE_APPLICATION_CREDENTIALS environment variable to be a path to a service account token file.

Getting error google.api_core.exceptions.ResourceExhausted: 429 Resource has been exhausted:

bash: pip: command not found:

  • Install pip
  • If your machine uses python2 by default, pip will also be the python2 version. Try using pip3 instead of pip.

pip install is hanging

Try upgrading pip

pip install --upgrade pip

pip install grcpio has been known to hang when you aren't using an upgraded version.

ImportError: No module named opentelemetry

Make sure you are using python3. If

python --version

returns Python 2.X.X try calling

python3 basic_trace.py
