Struct InstanceEventLog 

pub struct InstanceEventLog {
    pub restarts: VecDeque<DateTime<Utc>>,
    pub failures: VecDeque<DateTime<Utc>>,
}

Per-service ring of recent failure / restart timestamps. Pruning happens on every append: entries older than InstanceEventLog::WINDOW are dropped so the queues stay bounded to ~24h of activity regardless of service churn.

Fields

restarts: VecDeque<DateTime<Utc>>

Timestamps of operator/watchdog-triggered restarts.

failures: VecDeque<DateTime<Utc>>

Timestamps of observed instance failures — non-zero exits and individual health-check failures.

Implementations

impl InstanceEventLog

pub const WINDOW: Duration

Longest window any consumer needs; entries older than this are pruned eagerly on append.

pub fn record_restart(&mut self, now: DateTime<Utc>)

pub fn record_failure(&mut self, now: DateTime<Utc>)

pub fn failures_in(&self, now: DateTime<Utc>, window: Duration) -> u64

Number of failure events recorded in the last window from now.

pub fn restarts_in(&self, now: DateTime<Utc>, window: Duration) -> u32

Number of restart events recorded in the last window from now.

Trait Implementations

impl Debug for InstanceEventLog

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

Formats the value using the given formatter.

impl Default for InstanceEventLog

fn default() -> InstanceEventLog

Returns the “default value” for a type.
