复现流程：
长测配置，顺序数据。
启动测试后，运行脚本：
cat get_sg_tsfile-count.sh
#!/bin/bash
sg_res=" "
function sg_tsfile()
{
   tsfile_count=`ls -l 
/data/iotdb_data/data/sequence/root.test.g_${1}/0/0/*.resource|wc -l`
   sg_res="${sg_res} ${tsfile_count}"
}

while true
do
   for i in {0..49}
   do
      sg_tsfile ${i}
   done
   time=`date "+%Y-%m-%d %H:%M:%S"`
   echo "${time} ${sg_res} " >> sg_tsfile_res_0509.out
   sleep 2h
   sg_res=" "
done
