12.1. Enabling distributed tracing

The client offers distributed tracing based on the Jaeger implementation of the OpenTracing standard. Use the following steps to enable tracing in your application:

  1. Install the tracing dependencies.

    Red Hat Enterprise Linux 7

    $ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
    $ sudo yum install python2-pip
    $ pip install --user --upgrade setuptools
    $ pip install --user opentracing jaeger-client

    Red Hat Enterprise Linux 8

    $ sudo dnf install python3-pip
    $ pip3 install --user opentracing jaeger-client

  2. Register the global tracer in your program.

    Example: Global tracer configuration

    from proton.tracing import init_tracer
    
    tracer = init_tracer("<service-name>")

For more information about Jaeger configuration, see Jaeger Sampling.

When testing or debugging, you may want to force Jaeger to trace a particular operation. See the Jaeger Python client documentation for more information.

To view the traces your application captures, use the Jaeger Getting Started to run the Jaeger infrastructure and console.
