获取磁盘iops

环境:

Os:Centos 7

 

get_disk_iops.sh 

#!/bin/bash
# 定义目标磁盘
DEVICE="vdb"
# 第一次采样
read -r _ _ _ r1 _ _ _ _ w1 _ <<< $(grep $DEVICE /proc/diskstats)
sleep 1
# 第二次采样
read -r _ _ _ r2 _ _ _ _ w2 _ <<< $(grep $DEVICE /proc/diskstats)
# 计算IOPS
read_iops=$((r2 - r1))
write_iops=$((w2 - w1))
total_iops=$((read_iops + write_iops))
# 输出结果
echo "磁盘$DEVICE IOPS统计："
echo "读IOPS: $read_iops"
echo "写IOPS: $write_iops"
echo "总IOPS: $total_iops"
