This bundle adds a monolog processor to the OpentracingBundle to automatically enrich log contexts with the current span context.



This bundle is only an additional plugin and should not be installed independently. See its documentation for more information on installing the OpentracingBundle first.

Require dependencies

After you have installed the OpentracingBundle:

  • require the dependencies:
    composer req auxmoney/opentracing-bundle-monolog

Enable the bundle

If you are using Symfony Flex, you are all set!

If you are not using it, you need to manually enable the bundle:

  • add bundle to your application:
    # Symfony 3: AppKernel.php
    $bundles[] = new Auxmoney\OpentracingMonologBundle\OpentracingMonologBundle();
    # Symfony 4+: bundles.php
    Auxmoney\OpentracingMonologBundle\OpentracingMonologBundle::class => ['all' => true],


No configuration is necessary, the Monolog bundle extension will automatically load the provided Processor by tag.


Whenever a message is logged, the content is extended with extra information of the span context.
