Struct ServiceMetrics

pub struct ServiceMetrics {
    pub poll_count: u64,
    pub total_busy_duration: Duration,
    pub utilization: u8,
}

Collected metrics of a single service.

Fields

poll_count: u64

Amount of times the service was polled.

total_busy_duration: Duration

Total amount of time the service was busy.

The busy duration starts at zero when the service is created and is increased whenever the service is spending time processing work. Using this value can indicate the load of the given service.

This number is monotonically increasing. It is never decremented or reset to zero.

utilization: u8

Approximate utilization of the service based on its Self::total_busy_duration.

This value is a percentage in the range from [0-100] and recomputed periodically.

The measure is only updated when the when the service is polled. A service which spends a long time idle may not have this measure updated for a long time.
