linux查看io状态脚本

#查看占用io的进程

ps -eo pid,user,wchan=WIDE-WCHAN-COLUMN -o s,cmd|awk ‘ $4 ~ /D/ {print $0}’ #进程打开的文件 lsof -p $pid

使用block_dump

/etc/init.d/syslog stop echo 1 > /proc/sys/vm/block_dump sleep 60 dmesg | awk ‘/(READ|WRITE|dirtied)/ {process[$1]++} END {for (x in process) \ print process[x],x}’ |sort -nr |awk ‘{print $2 ” ” $1}’ | \ head -n 10 echo 0 > /proc/sys/vm/block_dump /etc/init.d/syslog start

以下为结果

Shutting down kernel logger: [ OK ] Shutting down system logger: [ OK ] kjournald(1860): 1156 pdflush(78): 716 kjournald(1861): 130 nginx(13571): 88 rm(21542): 85 find(21540): 67 nginx(13568): 65 nginx(13570): 41 php-cgi(13612): 37 nginx(13566): 34 Starting system logger: [ OK ] Starting kernel logger: [ OK ]

脚本下载 block_dump
