Core tracing prototype options

[hmstepanek]

Overview

Prototype of Core Tracing

• Add two new configuration settings:
  • distributed_tracing.drop_inprocess_spans.enabled - defaulted to False (Only reports entry and exit spans.)
  • distributed_tracing.unique_spans.enabled - defaulted to False (Only reports unique exit spans and entry spans.)
  • distributed_tracing.minimize_attributes.enabled - defaulted to False (Drops all agent attributes that are not entity synthesis attributes from spans)
    Note exit spans are defined as spans that contain entity synthesis agent attributes.
• Report additional metrics:
  • Time to process dropping spans and attributes. Note: attributes are dropped after attr processing intentionally to make time reporting easier.
  • Approximate amount of bytes or "cost" of core tracing/dropping in-process spans.
• Double adaptive sampling rate from default of 10 to 20 when Core Tracing is enabled.

Linking ErrorTraces, slow sql etc to distributed traces is not supported in the prototype.
