Adds support for metric collection at the filesystem instance level.
Metrics are pushed to the store upon the closure of a filesystem instance, encompassing all operations
that utilized that specific instance.
Collected Metrics:
- Number of successful requests without any retries.
- Count of requests that succeeded after a specified number of retries (x retries).
- Request count subjected to throttling.
- Number of requests that failed despite exhausting all retry attempts. etc.
Implementation Details:
Incorporated logic in the AbfsClient to facilitate metric pushing through an additional request.
This occurs in scenarios where no requests are sent to the backend for a defined idle period.
By implementing these enhancements, we ensure comprehensive monitoring and analysis of filesystem interactions, enabling a deeper understanding of success rates, retry scenarios, throttling instances, and exhaustive failure scenarios. Additionally, the AbfsClient logic ensures that metrics are proactively pushed even during idle periods, maintaining a continuous and accurate representation of filesystem performance.
