TelemetryCounters

Struct TelemetryCounters 

Source
pub struct TelemetryCounters { /* private fields */ }
Expand description

Always-on cumulative counters, shared across all engine components.

All increments use Ordering::Relaxed — these are statistical counters, not synchronization primitives.

Implementations§

Source§

impl TelemetryCounters

Source

pub fn increment_queries(&self)

Increment the query counter by one.

Source

pub fn increment_writes(&self, row_count: u64)

Increment the write counter by one and add row_count to the row total.

Source

pub fn increment_errors(&self)

Increment the error counter by one.

Source

pub fn increment_admin_ops(&self)

Increment the admin operations counter by one.

Source

pub fn snapshot(&self) -> TelemetrySnapshot

Read all counters into a TelemetrySnapshot.

The sqlite_cache field is left at defaults — callers that need cache status should populate it separately via read_db_cache_status.
