Response time
Response time measures how long each provider takes to accept a push API request from Knock, including connection overhead and any automatic retries. Lower values mean faster notification hand-off.
| Provider | Median (p50) | p90 | p95 | p99 |
|---|---|---|---|---|
| 65ms | 114ms | 131ms | 180ms |
| 215ms | 336ms | 472ms | 1188ms |

The highest daily p99 was 308ms for Apple Push (APNS) and 15150ms for OneSignal, indicating the worst-case response time during spikes or provider-side congestion. Apple Push (APNS) shows a tighter tail, which may matter for time-sensitive push notifications like real-time alerts where even rare delays can impact user experience.
Error rate
Error rate tracks the ratio of 5xx responses and timeouts to total push API requests. Knock automatically retries failed requests, so transient provider errors rarely affect end-user delivery.
| Provider | Avg. daily error rate | Highest daily rate | Peak error date | Zero-error days | Days above 0.01% |
|---|---|---|---|---|---|
| 0.00% | 0.00% | Mar 25 | 91 | 0 |
| 0.07% | 2.88% | Apr 13 | 78 | 7 |
Averaged across the date range, Apple Push (APNS) shows a 0.00% daily error rate compared to 0.07% for OneSignal. The highest single-day error rate was 0.00% for Apple Push (APNS) and 2.88% for OneSignal. Apple Push (APNS) demonstrates a lower error rate, indicating slightly more consistent availability during this period. Knock automatically retries failed requests to both providers, minimizing the impact of transient errors on end-user delivery.
About these metrics: Data represents notifications sent through Knock during the specified period. Response time measures time from Knock to provider acceptance. Error rate includes only provider 5xx responses and timeouts.
