}

Counters with placement, admission, and miss detail. BPF holds 17 counters, Rust adds display-only uptime for eighteen.

Fields

on_cpu: u64

Tasks now on a CPU

total_runtime: u64

Total runtime in nanoseconds

uptime_ns: u64

Display-only uptime since attach in nanos with no BPF use. Filled from the start instant, never from the BPF counters. Uptime since attach in nanoseconds

inserts: u64

Fresh deadline joins

requeues: u64

Runnable slice ends with requeue

completions: u64

Blocks and exits

local_moves: u64

Moves from the local tier

node_moves: u64

Moves from the node tier

machine_moves: u64

Moves from the machine tier

kicks: u64

Idle wakeup kicks sent after insert

admits: u64

Tasks admitted with no bound

rejects: u64

Rejects dead at zero whitelisted for wire compat with no writer; real rejects count in gate_rejects

misses: u64

Wall completions past deadline

gate_rejects: u64

Closed gate rejects on stale CPUs plus tasks

preempt_kicks: u64

Busy preempts sent with margin plus tail

preempt_skipped: u64

Preempts held by margin plus tail plus eligibility

red_rejects: u64

RED overload rejects to the value ordered queue

red_reclaims: u64

RED reclaims from the value ordered queue

Implementations

impl Metrics

fn format<W: Write>(&self, w: &mut W) -> Result<()>

pub fn delta(&self, rhs: &Self) -> Self

Interval delta of the counters over the poll interval. Gauges like on_cpu plus uptime_ns pass through as live values.

Trait Implementations

impl Clone for Metrics

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Metrics

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

Formats the value using the given formatter.

impl Default for Metrics

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Metrics

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Meta for Metrics

fn meta() -> StatsMeta

impl Serialize for Metrics

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
