Upgrading to 0.38.0

Integrations

Celery

  • Support for distributed tracing was added in #1194. It is default disabled but is easily enabled via DD_CELERY_DISTRIBUTED_TRACING=true or via the config API ddtrace.config.celery['distributed_tracing'] = True. Thanks @thieman!
  • Analyzed span configuration was added to easily configure Celery spans to be analyzed. This can be done via the environment variable DD_CELERY_ANALYTICS_ENABLED=true or with the config API ddtrace.config.celery['analytics_enabled'] = True.

Django

  • A config option was added to allow enabling/disabling instrumenting middleware. It can be set with the environment variable DD_DJANGO_INSTRUMENT_MIDDLEWARE=true|false or via the config API ddtrace.config.django['instrument_middleware'] = False # default is True.

Core

  • Runtime ID tag support for traces and profiles. This will allow us to correlate traces and profiles generated by applications.

OpenTracing

  • Support for active_span() was added to our OpenTracing tracer.

Profiling

  • Storing of span id in profiling events which will enable linking between a trace and a profile in the product.

Tracer

  • DD_TAGS environment variable added to replace DD_TRACE_GLOBAL_TAGS.
