VOLUME.STATS RESET

Resets operation counters to zero for a named volume.

Syntax

VOLUME.STATS <volume-name> RESET

Parameters

Parameter	Type	Description
volume-name	string	Name of the volume, in <kind>-shard-<id> format (e.g. bucket-shard-0)

Return Value

Simple string OK.

Behavior

Resets the volume’s operation counters (appends, deletes, updates, gets, bytes_appended, bytes_read, segments_created) to their default values (zero).

This affects only in-memory counters. Segment-level statistics (size, used_bytes, free_bytes, cardinality) are derived from FoundationDB metadata and are not affected by reset.

This command is available on the management port (default 3320).
