Struct CountersSnapshot 

pub struct CountersSnapshot {
    pub requests: u64,
    pub unauthorized: u64,
    pub throttled: u64,
    pub failed: u64,
    pub duration_us: u64,
}

One reading of Counters, taken field by field.

The fields are not read atomically with respect to each other, which is the ordinary bargain for a metrics scrape: a counter may be one request further along than the one beside it. An alert on a rate over a scrape interval cannot see the difference.

Fields

requests: u64

Requests served, whatever their status.

unauthorized: u64

Requests refused as unauthenticated or forbidden (401, 403).

throttled: u64

Requests refused by a rate limit or a quota (429).

failed: u64

Requests the node failed to serve (5xx, and I/O errors mid-write).

duration_us: u64

Total time spent serving, microseconds. With requests, this is the pair an average-latency alert needs.
