This stat sync type should be used for counter metrics (i.e it should only increase with time). It should only be manipulated using TSStatIntIncrement. E.g for tracking call counts or uptime.
.. c:member:: TSStatSync TS_STAT_SYNC_AVG
Values should be arithmetically averaged.
.. c:member:: TSStatSync TS_STAT_SYNC_TIMEAVG
Values should be arithmetically averaged over a time period.
