Module counter_descriptor 

Nested message and enum types in CounterDescriptor.

Enums

Scope

The scope of a counter instance: which stream of values the per-sample weights belong to. Counter instances accumulate independently, so values from different instances must never be merged into one stream. Trace processor keeps sampling streams separate and materializes one counter track per instance within each stream: SCOPE_GLOBAL yields one track per sampling stream and SCOPE_CPU one track per (sampling stream, cpu).

UnitField

The unit weights are expressed in. Set the well-known unit when one fits, otherwise set unit_str to a custom label.
