Struct EventSnapshot 

pub struct EventSnapshot {
    pub timestamp: DateTime<Utc>,
    pub pending: u64,
    pub active: u64,
    pub succeeded: u64,
    pub failed: u64,
    pub retried: u64,
    pub revoked: u64,
    pub queue_depth: u64,
    pub worker_count: u64,
    pub queue_depths: HashMap<String, u64>,
}

Periodic aggregate snapshot of cluster state.

A snapshot is a point-in-time summary suitable for dashboards, persistence, and as an input to AlertEvaluator. All counts are plain integers so the type serializes compactly.

Fields

timestamp: DateTime<Utc>

When the snapshot was taken.

pending: u64

Number of tasks currently pending (sent but not started).

active: u64

Number of tasks currently active/running.

succeeded: u64

Number of tasks that have succeeded (in the aggregation period).

failed: u64

Number of tasks that have failed (in the aggregation period).

retried: u64

Number of tasks retried (in the aggregation period).

revoked: u64

Number of tasks revoked (in the aggregation period).

queue_depth: u64

Total depth across all queues.

worker_count: u64

Number of workers considered online.

queue_depths: HashMap<String, u64>

Optional per-queue depth breakdown.

Implementations

impl EventSnapshot

pub const fn completed(&self) -> u64

Total number of terminal task outcomes recorded (succeeded + failed).

pub fn failure_rate(&self) -> f64

Failure rate over completed tasks (failed / (succeeded + failed)).

Returns 0.0 when no tasks have completed.
