Inaccurate Reporting of Gauge Metrics in Legacy Metrics Implementation

[VinozzZ]

The current implementation of Gauge metrics in the Legacy Metrics system only stores the latest value for each metrics key. As a result, during a metrics reporting interval, only the most recent value is captured and reported.

This behavior can lead to inaccurate metrics under certain conditions:

• If values are updated frequently, but the reporting interval is set to a longer duration, the final reported value may not accurately reflect the range or variability of the data.
• The reporting may miss intermediate updates, leading to a skewed representation of the actual metric over time.
