Description

Recently, when trying to locate some performance bottleneck, we opened the OpTracker. However, we found that events "header_read", "throttled", "all_read" and "all_read" are missing. After reading the source code, we believe that this is because the "tracking_start" method is invoked in create_request after the construction of TrackedOps.
