      Before this update, a race condition could cause the vector_buffer_byte_size and vector_buffer_events gauges to report negative values under certain system load and timing conditions. With this update, a concurrent, centralized state tracker ensures these metrics are always reported as non-negative values.

      vector_buffer_byte_size

      The metric sometimes reports negative values, which is incorrect. This metric is intended to represent the current number of bytes stored in a Vector component’s buffer and should never be negative.

      A similar bug has arisen in Upstream as well.

      This metric is important because it helps monitor buffer usage and detect potential issues like buffer overflows or data loss. Negative values undermine its reliability for monitoring and alerting.
