# Boto3 Retrier Configuration
|
|
|
|
Prowler's AWS Provider uses the Boto3 [Standard](https://boto3.amazonaws.com/v1/documentation/api/latest/guide/retries.html) retry mode to assist in retrying client calls to AWS services when these kinds of errors or exceptions are experienced. This mode includes the following behaviours:
|
|
- A default value of 3 for maximum retry attempts. This can be overwritten with the `--aws-retries-max-attempts 5` argument.
|
|
- Retry attempts for an expanded list of errors/exceptions:
|
|
```
|
|
# Transient errors/exceptions
|
|
RequestTimeout
|
|
RequestTimeoutException
|
|
PriorRequestNotComplete
|
|
ConnectionError
|
|
HTTPClientError
|
|
|
|
# Service-side throttling/limit errors and exceptions
|
|
Throttling
|
|
ThrottlingException
|
|
ThrottledException
|
|
RequestThrottledException
|
|
TooManyRequestsException
|
|
ProvisionedThroughputExceededException
|
|
TransactionInProgressException
|
|
RequestLimitExceeded
|
|
BandwidthLimitExceeded
|
|
LimitExceededException
|
|
RequestThrottled
|
|
SlowDown
|
|
EC2ThrottledException
|
|
```
|
|
- Retry attempts on nondescriptive, transient error codes. Specifically, these HTTP status codes: 500, 502, 503, 504.
|
|
|
|
- Any retry attempt will include an exponential backoff by a base factor of 2 for a maximum backoff time of 20 seconds.
