-----------------------------------
My test result is ok in TRUNK .
I find requests is average value in version 0.90.2, but it is a sum in TRUNK .
so ,I make a patch for TRUNK again.
It looks readRequestsCount and writeRequestsCount is inaccurate.
The result is:
Hmaster:
C4C3.site:60030 1304500382940C4C3.site,60020,1304500382940 requests=85231,
regions=12, usedHeap=682, maxHeap=8175
Region server:
requests=85529, regions=12, stores=12, storefiles=31, storefileIndexSize=8,
memstoreSize=481, readRequestsCount=0,
writeRequestsCount=27337, compactionQueueSize=4, flushQueueSize=0,
usedHeap=708, maxHeap=8175, blockCacheSize=14065536,
lockCacheFree=1700434944, blockCacheCount=0, blockCacheHitCount=0,
blockCacheMissCount=132049, blockCacheEvictedCount=0,
blockCacheHitRatio=0, blockCacheHitCachingRatio=0
> request is always zero in WebUI for region server
