Description

Context

Currently, our error metrics don't distinguish between distribution failures that are permanent and will fail even if retried, or failures that succeed after being retried.
We want to improve this in order to be able to differentiate both scenarios.

Solution

Failure metric should be labeled by:

• Transient failure
• Permanent failure

Proposed approach

We can distinguish both these scenarios by using the following rationale:

• Transient failures happen whenever a package is distributed successfully but had more than 1 attempt at being distributed: retries > 0
