示例1: printStats
import org.apache.hadoop.hbase.io.hfile.HFile; //导入方法依赖的package包/类
private void printStats(long elapsedTime) {
long numSeeksL = numSeeks.get();
double timeSec = elapsedTime / 1000.0;
double seekPerSec = numSeeksL / timeSec;
long kvCount = numKV.get();
double kvPerSec = kvCount / timeSec;
long bytes = totalBytes.get();
double bytesPerSec = bytes / timeSec;
// readOps and preadOps counters get reset on access, so we have to
// accumulate them here. HRegion metrics publishing thread should not
// be running in this tool, so no one else should be resetting these
// metrics.
totalSeekAndReads += HFile.getReadOps();
totalPositionalReads += HFile.getPreadOps();
long totalBlocksRead = totalSeekAndReads + totalPositionalReads;
double blkReadPerSec = totalBlocksRead / timeSec;
double seekReadPerSec = totalSeekAndReads / timeSec;
double preadPerSec = totalPositionalReads / timeSec;
