Hi,

Use-case for my system is to implement retry logic with backoff time (exponential) when there is HTTP error code 429.  
We have implemented the custom logic to achieve this using **tryMax** and **pause**.

But the issue we are facing is for each failure as part of retry, error count (KO) is added.

eg: calling SvcA with retry attempts of 5.

If first 3 retries filed, KO count is 3. This makes gatling report extremely hard to understand and also for the assertion rules.

Is there a way to suppress or mark the API call as NOT failed inside the **tryMax?**

Thanks,  
Kamal T

You’ll have to implement you own logic with asLongAs.
