Notes
This release of the Python agent includes improvements to distributed tracing, and bug fixes.
The agent can be installed using easy_install/pip/distribute via the Python Package Index or can be downloaded directly from the New Relic download site.
New Features
Add new span attribute transaction.name
A new attribute,
transaction.name, has been added to the root span.
Improved features
Transaction attributes are added to the root span
Transaction attributes, including response attributes, are now added to the root span.
Custom attributes are added to the root span
The public API methods
newrelic.agent.add_custom_paramandnewrelic.agent.add_custom_paramsnow add the specified custom attribute to the root span in addition to the transaction. If the maximum number of custom attributes is reached, span-level custom attributes take precedence over transaction-level custom attributes.Error attributes added to each span/segment
Error attributes
error.classanderror.messageto all spans that exit without handling an exception.
Bug fixes
asyncio: application crash when a transaction that started on a completed parent task exits
When a transaction that started on a completed parent task exited, an exception was raised. This error has been fixed.
Error attributes are no longer added if the error collector is disabled
If the error collector is disabled via error_collector.enabled, error attributes
error.classanderror.messageare not added to the currently executing span.
Security Updates
Note that changes were made that add attributes to the root span. Transaction-level attribute filtering via the transaction.attribute.exclude configuration setting will not filter the attribute(s) for the root span. Those attributes may unexpectedly start to appear on the root span.
