此脚本用于采集用户对于IoTDB的使用情况。
该脚本的启动命令如下：
./diagnose-iotdb.sh $IOTDB_DATA_DIR $IOTDB_HOME_DIR $IOTDB_CONF_DIR
# 比如
./diagnose-iotdb.sh /opt/iotdb/apache-iotdb-0.13.3-all-bin/data /opt/iotdb/apache-iotdb-0.13.3-all-bin /opt/iotdb/apache-iotdb-0.13.3-all-bin/conf此时会输出用户使用相关的情况，输出结果如下：
#check total data size
4.0K ./wal
12K ./system
16K ./data
80K .
#check data/ size
80K .
#check / tsfile size
700
#top 100 / TsFile size
351
349
#check / resource size
119
#top 10 / resource size

#check / mods size
#top 100 / mods size
#check data/sequence size
80K .
#check /sequence tsfile size

#top 100 /sequence TsFile size

#check /sequence mods size

#check data/unsequence size
80K .
#check /unsequence tsfile size
#top 100 /unsequence TsFile size
#check /unsequence resource size
#top 10 /unsequence resource size
#check /unsequence mods size
#top 100 /unsequence mods size
#sg number

然后在执行脚本的目录中会有iotdb-engine.properties.result与iotdb-env.sh.result文件，这两个文件是用户的配置文件。
