How to implement CPU load Monitoring script
This article will explain in detail how to implement the CPU load monitoring script. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.
The code is as follows:
#! / bin/bash
Load= `uptime`
Shijian= `date +% YMUE% mMUE% dMui% T`
File=cpustatus.txt
Touch $file
All= `cat $file | wc-l`
Printf "$load $shijian\ n" > > $file
If [$all > 60]; then
Starttime= `cat $file | awk'{print $13}'| sort-r | tail-1`
Stoptime= `cat $file | awk'{print $13}'| sort-n | tail-1`
Loadavg= `cat $file | awk'{avg1+=$10;avg2+=$11;avg3+=$12} END {print avg1/NR,avg2/NR,avg3/NR}'`
High= `cat $file | awk'{print $10}'| sort-n | tail-1`
Low= `cat $file | awk'{print $10}'| sort-r | tail-1`
Printf "$starttime\ n load average $loadavg\ nhigh $high\ nlow $low\ n $stoptime\ n\ n" > j
# printf "load average $startus\ n" > > j
# mv $f $f.roomb
Fi
It is better to use it with Crontab
The following is written by another person, and share it.
The code is as follows:
#! / bin/bash
# extract the IP address information of this server
IP= `ifconfig eth0 | grep "inet addr" | cut-f 2-d ":" | cut-f 1-d "" `
# extract the number of CPU on this server
Cpu_num= `grep-c 'model name' / proc/ cpuinfo`
Count_uptime= `uptime | wc-w`
# APCge load of the current system for 15 minutes
Load_15= `uptime | awk'{print $'$count_uptime'}'`
# obtain the average load value of a single core of the current system for 15 minutes. If the result is less than 1.0, the first digit is 0.
Average_load= `echo "scale=2;a=$load_15/$cpu_num;if (length (a) = = scale (a)) print 0X print a" | bc`
# take the integer of the average load value above
Average_int= `echo $average_load | cut-f 1-d "." `
# get the warning value for executing shell input (within 0-100)
Warn_input=$1
If [[! $warn_input = ~ ^ [0-100] + $]]
Then
Exit 0
Else
If [["$warn_input"-lt 0 | | "$warn_input"-gt 100]]
Then
Exit 0
Else
Load_warn=$ (($warn_input/100))
Fi
Fi
If [$average_int-gt 0]
Then
Echo "$IP server average load of a single core for 15 minutes is $average_load, which exceeds the warning value of 1.0.Please deal with it immediately! $(date +'% Y-%m-%d% HRV% MRV% S')"
Else
Load_now= `expr $average_load\ > $load_ Warn`
If [$load_now-eq 1]
Then
Echo "$IP server average load of a single core for 15 minutes is $average_load, which exceeds the warning value of 0.7.Please deal with it immediately! $(date +'% Y-%m-%d% HRV% MRV% S')"
Else
Echo "$IP server average load value of a single core for 15 minutes is $average_load,cpu core is $cpu_num, and the average load of the system for 15 minutes is $load_15 load normal $(date +'% Y-%m-%d% Haverage_load,cpu% MRV% S')"
Fi
Fi
