Notes
This release of the Python agent adds support for excluding attributes from span events and transaction trace segments, adds a new api called add_custom_parameters, and includes various 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.
Features
Add ability to exclude attributes from span events and transaction trace segments
This release adds support to exclude attributes (such as
http.url) from span events (via thespan_events.include/span_events.excludeoptions) and from transaction segments (via thetransaction_segments.include/transaction_segments.excludeoption).As with other attribute destinations, these new options will inherit values from the top-level
attributes.include/attributes.excludesettings. See the documentation for more information.Add public add_custom_parameters API
The method add_custom_parameters on Transaction is now exposed through newrelic.agent.add_custom_parameters
Bug Fixes
Transaction counts were not reported for aiohttp's built-in error pages
When a built-in error route was reached in aiohttp (such as a 404 due to a missing route), transactions were not recorded. As a result, the transaction counts may have been artificially low. aiohttp system route traffic will now be reported.
aiohttp cross application tracing linking to non-Python applications may have been omitted if using multidict<3.0
For aiohttp users using multidict versions less than 3.0, cross application tracing HTTP headers may have been generated in a way that was incompatible with non-Python applications. Headers are now generated in a format compatible with all New Relic agents.
aiohttp 3.5.x versions generated agent instrumentation errors
The agent previously failed to instrument aiohttp applications running versions 3.5.0 and greater. The agent now supports aiohttp versions up to 3.5.1.
