通过shell脚本抓取存储home用户的空间使用情况，写到excel文件里，再导入到mysql数据库，最后通过grafana进行展示

grafana配mysql略
查询用户总数：
select UNIX_TIMESTAMP(time) as time_sec, count(*) as Total from userquota group by time_sec;
查询各home用户数：
select UNIX_TIMESTAMP(time) as time_sec, count(*) as home8 from userquota where home='home8' group by time_sec;
查询单个人空间使用情况语句：
SELECT UNIX_TIMESTAMP(time) as time_sec, used as 'zhi.yang' FROM userquota WHERE user='zhi.yang';
查询平均空间使用情况语句：
select Unix_timestamp(time) as time_sec, avg(used) from userquota group by time_sec;
统计各空间段的人数：
select unix_timestamp(time) as time_sec, count(*) as '=0' from userquota where used = '0' group by time_sec;
select unix_timestamp(time) as time_sec, count(*) as '<=50G' from userquota where used > '0' and used <= '52144000' group by time_sec;
select unix_timestamp(time) as time_sec, count(*) as '50G
