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.
