Notes
This release of the Python agent adds support for Kombu, mysqlclient, PyMySQL, and adds a few safeguards to prevent exceptions.
Install the agent using easy_install/pip/distribute via the Python Package Index or download it directly from the New Relic download site.
New features
Add support for Kombu
- Add support for producer and consumer message tracing in Kombu.
- In the case where Celery and Kombu are used together, a transaction is produced for both Celery and Kombu message consumption and Kombu consumer tracing is turned off by default. It can be enabled via the
instrumentation.kombu.consumer.enabledsetting. A new settinginstrumentation.kombu.ignored_exchangesto ignore certain exchanges was also added and by default it ignores the celeryev queue which is a monitoring queue.
Add support for mysqlclient (a MySQLdb fork for Python 3)
- Instrumentation for the Python 2 library MySQLdb has been adapted to support the Python 3 fork mysqlclient.
Update instrumentation for PyMySQL for versions 1.0.3 and above
- Instrumentation for PyMySQL has been updated for newer versions of the library, and versions below 1.0.3 are no longer supported.
Bug fixes
Safeguard startup of agent healthchecks against exceptions
- Previously, the agent healthchecks could raise exceptions during startup, potentially resulting in agent crashes. This has been fixed.
Fix warning message around garbage collection runtime metrics sampler
- Previously, a warning message was sometimes emitted which was related to the garbage collection runtime metrics sampler. This has been fixed.
