This read-only INTEGER is a running total of bytes received across all samples since the agent (SA) was started for this test, noted in the DESCRIPTION as a counter that will eventually wrap. An admin uses this as a cumulative data-transfer tally for capacity or usage tracking rather than a per-sample metric. Because it wraps, an admin graphing svcRspTableTotalBytesIn over long uptimes should watch for and handle counter rollover.
