class Diagnostics

Defined at line 22 of file ../../src/storage/fvm/driver/diagnostics.h

Diagnostics exposes internal information and metrics recorded by FVM to the rest of the system

via the Inspect API.

This object owns a VMO which it publishes metrics into; this VMO is read by the inspect

framework and can be accessed through (e.g.) iquery.

This class is thread-safe and movable.
