每隔10秒监控磁盘空间使用情况

# cat checkdf.sh
#!/bin/bashwhile :
do/u02/jk/df_var.shsleep 10 # 延迟10秒执行
done

本次监控某系统目录

# cat df_var.sh
#!/bin/bash
LOG=/u02/jk/df_`hostname -s`_`date +'%Y-%m-%d'`.log
每日生成一个文件，且各主机可共用同一脚本，依据主机名区分#粗略展示
echo '***zzz'  `date +'%Y-%m-%d %H:%M:%S'` >>$LOG
df -h |grep var >>$LOG
du -sm /var/* >>$LOG#细节展示
i=`du -sm /var/*|sort -rn|head -2|awk '{print $2}'`
for a in $i; do echo '---' $a >>$LOG ;cd $a;du -sm * $a|sort -rn|head >>$LOG; done
exit 0

启动：nohup sh ./checkdf.sh &
停止：ps -ef|grep checkdf|grep -v grep|awk '{print $2}' |xargs kill -9
