Python agent v9.6.0

Notes

This release of the Python agent fixes a bug when specifying processors in structlog, and updates the NewRelicLogForwardingHandler to support dictionary type logs and formatters.

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

• Support dictionary type logs in NewRelicLogForwardingHandler

  • Dictionary type log messages are now supported in NewRelicLogForwardingHandler when passed as the log message, or when a custom formatter returns a dictionary.
  • The key message will be extracted if available and treated as the log message, and any other items will be considered context data attributes and prefixed with message..
    • These attributes are subject to the same filtering rules as other context data. The message. prefix is not considered when filtering attributes from logs.
    • To report these attributes, enable context data forwarding and optionally configure include and exclude rules to filter the allowed attributes.

• Support logging formatters in NewRelicLogForwardingHandler

  • Logging formatters added with setFormatter() are now supported, and may return a string or dicitionary log message type to be forwarded to New Relic.

Bug fixes

• Fix a bug when specifying processors in structlog
  • Previously, there was a bug in the structlog instrumentation where processors was assumed to be list type. Now the instrumentation supports processors of all iterable types.
