Assumes independent attempts with one constant failure probability and no retry delays, rate limiting or outage correlation. Work-seconds per window estimates average in-flight work, not peak concurrency.

How to use Retry Attempt Load Estimator

Explore the worked example. Compare catalog, checkout and upload traffic with different failure probabilities and maximum attempt counts.
Replace the request groups with your own entries. Set traffic window · seconds.
Choose “Estimate retry traffic”. Review retry traffic estimates, then compare the visual overview with the detailed tables.
Capture alternative scenarios, download a reusable project and export the selected table or a report when you are ready.

A starting point

Compare catalog, checkout and upload traffic with different failure probabilities and maximum attempt counts. The example is illustrative and can be replaced.

Know what you are comparing

What does maximum attempts include?

It includes the original request. Three maximum attempts means one initial attempt and up to two retries. Failures are assumed independent with a constant probability.

Files, privacy & saving
