Added

• Enhance logging #2490
  • This features two new logging options:
    • datadog.trace.log_level allows more fine-grained control over logging (error, warn, info, debug, trace). It follows the RUST_LOG standard. Note that datadog.trace.debug still takes precedence if set.
    • datadog.trace.log_file allows specifying a dedicated target file for any datadog trace logs instead of the default php error location.
  • More log lines were added to allow for observing submitted spans (debug level) and hook invocations (trace level).

Profiling

This release requires System INIs to be used to configure the profiler settings which control the enabling/disabling of individual features. If you are configuring the profiler using php datadog-setup.php config set, you should be fine. We recommend switching to use the config mode of datadog-setup.php to configure profiling.

Added

• Enable timeline by default #2480. This can be disabled by setting the INI setting datadog.profiling.timeline_enabled to 0 or false. Using the datadog-setup.php script is recommended, for example:

  php datadog-setup.php config set --php-bin all -ddatadog.profiling.timeline_enabled=0

Exception profiling is now enabled by default. You can manage it using the DD_PROFILING_EXCEPTION_ENABLED environment variable or the datadog.profiling.exception_enabled setting in the INI file. Although the DD_PROFILING_EXPERIMENTAL_EXCEPTION_ENABLED environment variable and datadog.profiling.experimental_exception_enabled INI setting still work, the new ones take precedence.
