Worked on the percona/percona-server-mongodb repository to address network statistics accuracy under rate limiting. Focused on backend development using C++ and network monitoring techniques, the developer modified the SessionWorkflow so that logical input bytes are counted before the rate-limiting check, ensuring that even rejected requests are accurately reflected in network usage metrics. This adjustment resolved an issue where network counters previously missed data from rejected requests. To validate the fix, a unit test was added to confirm that network statistics now include all relevant traffic. The work improved the reliability of network monitoring without introducing new features during the period.
