Struct MethodMetrics 

pub struct MethodMetrics {
    pub requests: u64,
    pub errors: BTreeMap<String, u64>,
    pub latency_buckets: [u64; 11],
    pub total_micros: u64,
    pub max_micros: u64,
    pub per_minute: Vec<(u64, u64)>,
}

What the counters hold for one method.

Fields

requests: u64

Requests that reached the handler.

errors: BTreeMap<String, u64>

Requests that returned an error, by error code.

latency_buckets: [u64; 11]

Requests per latency bucket: index i counts latencies up to LATENCY_BOUNDS_MS[i], the last index everything slower.

total_micros: u64

Sum of the latencies, microseconds.

max_micros: u64

The slowest request, microseconds.

per_minute: Vec<(u64, u64)>

(minute since the epoch, requests in it), oldest first, at most the last hour.

Implementations

impl MethodMetrics

pub fn error_count(&self) -> u64

Requests that returned an error, in all.

pub fn requests_in_minute_of(&self, now: SystemTime) -> u64

Requests in the minute that contains now (wall clock), for a rate reading.
