A shell script used to count the hard disk usage of CPU memory

Copy codeThe Code is as follows :#! /Bin/bash
# This script is used for describle CPU Hard Memery Utilization
Total = 0
Idle = 0
System = 0
User = 0
Nice = 0
Mem = 0
Vmexec =/usr/bin/vmstat
Which sar>/dev/null 2> & 1
If [$? -Ne 0]
Then

Nice = 0
Temp = 'vmstat 1 3 | tail-1'

During the development of CFS, You need to monitor the machine's real-time memory, CPU, and hard disk usage, because CFS runs on a Linux machine, some virtual files in Linux can be used to calculate the memory CPU usage. Therefore, the following script is compiled, which is simple but practical.

It consists of three parts: hard disk usage, memory usage, and CPU usage.

Copy codeThe Code is as follows :#! /Bin/sh

# Count cpu_used_rate, memory_used_rate, disk_used_rate
# @ Jayson 2012-5

# Disk_used_rate
# Depend on real storage place the parameter 'location' need to alter.
# My files are mainly stored in the sda8 partition, so this is extracted.
Location =/dev/sda8
Disk_Used_Rate = $ (df-h | grep $ Location | awk '{print $5 }')
Echo $ Disk_Used_Rate

# Memory_used_rate
LoadMemory = $ (cat/proc/meminfo | awk '{print $2 }')
Total = $ (echo $ LoadMemory | awk '{print $1 }')
Free1 = $ (echo $ LoadMemory | awk '{print $2 }')
Free2 = $ (echo $ LoadMemory | awk '{print $3 }')
Free3 = $ (echo $ LoadMemory | awk '{print $4 }')

Used = 'expr $ Total-$ Free1-$ Free2-$ Free3'
Used_Rate = 'expr $ Used/$ Total * 100 | bc-l'
Memory_Used_Rate = 'expr $ Used_Rate/1 | bc'
Echo $ Memory_Used_Rate %

Log1 = $ (cat/proc/stat | grep 'cpu '| awk' {print $2 "" $3 "" $4 "" $5 "" $6 "" $7 "" $8 }')
