PascalWithopf	bd8a1b8136	freeBSD: disable tests that are not working ... FreeBSD is not able to run all tests, therefore all tests that can't be run will be disabled.	2017-10-27 12:18:59 +02:00
Janmejay Singh	8e54306bc7	migrated overflow test to imdiag<->statsobj coordination from elapsed-time-based-coordination (as this too is failing on builtbot fedora32x32)	2016-04-19 00:43:09 +05:30
Janmejay Singh	5f071af97f	Fixed dyn-stats unused-metric-ttl bug which was was expected to garbage-collect accumulators that were unused for time-period >= ttl, but used to wipe all accumulators. This worked from memory-footprint and metric-life point-of-view, but used to reset accumulators even when they were configured to not be reset. Now it maintains survivor(shadow) table which keeps the accumulator value around from ttl up-to (2 * ttl) and reclaims it only if no dyn_inc call resurrects it by the end of this period. This allows us to resurrect surviving counters if they are used within ttl duration. This keeps a counter alive up-to (2 * ttl) in the worst case(late eviction) and ttl(timely eviction) in the best case.	2016-04-14 21:03:35 +05:30
Janmejay Singh	c66402598e	Re-sync with dynstats recycle interval(as opposed to stats flush interval, which happens multiple-times per recycle). This was a bug in the way test was written. Introduced a new counter in dyn-stats subsystem which is incremented every time metrics in dyn-stats bucket are recycled.	2016-02-21 00:51:48 +05:30
Janmejay Singh	7a96794b12	made some changes to dyn-stats tests to make it more resillient to timing-problems (prevents bad-timing introduced occasional failures)	2015-11-17 17:48:59 +05:30
Janmejay Singh	c4a9e693c6	ensured dynstats overflow tests actually excercise 1 non-metric-name-resetting cycle too	2015-11-16 17:08:03 +05:30
Janmejay Singh	33cb11db57	dynstats reset-of-accumulated-dyn-metric-names and more-metrics-than-expected flows fixed and tested	2015-11-16 16:43:51 +05:30
