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;

  boolean isRead = workload == Workload.RANDOM_READS;

  StringBuilder sb = new StringBuilder();
  sb.append("Time: " +  (long) timeSec + " sec");
  if (isRead)
    sb.append(", seek/sec: " + (long) seekPerSec);
  sb.append(", kv/sec: " + (long) kvPerSec);
  sb.append(", bytes/sec: " + (long) bytesPerSec);
  sb.append(", blk/sec: " + (long) blkReadPerSec);
  sb.append(", total KV: " + numKV);
  sb.append(", total bytes: " + totalBytes);
  sb.append(", total blk: " + totalBlocksRead);

  sb.append(", seekRead/sec: " + (long) seekReadPerSec);
  sb.append(", pread/sec: " + (long) preadPerSec);

  if (isRead)
    sb.append(", unique keys: " + (long) keysRead.size());

  LOG.info(sb.toString());
}
