Detailed Description

Thread-safe counters describing client-side networking activity.

Semantics:

• requests counts finished transfer attempts (successful or not).
• retries counts retry cycles triggered by retryable outcomes.
• sleep_ms is the total backoff time slept between attempts.
• network_ms is the accumulated wall-clock duration spent inside libcurl for performed requests (sum over attempts).
• bytes_received sums body sizes appended via the write callback.
• statuses[i] counts responses with HTTP status i (0..599). Values outside the array bounds are ignored.

All counters are atomics and rely on the default sequentially consistent operations provided by std::atomic. Readers observe eventually consistent snapshots without additional synchronization.

Constructor & Destructor Documentation

network_metrics()

corespace::network_metrics::network_metrics

(

)

Zero-initialize per-status counters.

The constructor explicitly clears the statuses histogram.

    for (auto& status : statuses) {
        status.store(0, std::memory_order_relaxed);
    }
}
