Enum rocksdb::statistics::StatsLevel

#[repr(u8)]
pub enum StatsLevel {
    DisableAll = 0,
    ExceptHistogramOrTimers = 2,
    ExceptTimers = 3,
    ExceptDetailedTimers = 4,
    ExceptTimeForMutex = 5,
    All = 6,
}

StatsLevel can be used to reduce statistics overhead by skipping certain types of stats in the stats collection process.

Variants

DisableAll = 0

Disable all metrics

ExceptHistogramOrTimers = 2

Disable timer stats, and skip histogram stats

ExceptTimers = 3

Skip timer stats

ExceptDetailedTimers = 4

Collect all stats except time inside mutex lock AND time spent on compression.

ExceptTimeForMutex = 5

Collect all stats except the counters requiring to get time inside the mutex lock.

All = 6

Collect all stats, including measuring duration of mutex operations. If getting time is expensive on the platform to run, it can reduce scalability to more threads, especially for writes.

Trait Implementations

impl Clone for StatsLevel

fn clone(&self) -> StatsLevel

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StatsLevel

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StatsLevel

fn eq(&self, other: &StatsLevel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
