Shell script to check total CPU and Memory consumption

[nixsupport]

Hi,

Here is a simple shell script to check total CPU and Memory consumption by Linux Servers.

#!/bin/bash
echo "`date +"%D %T"` `ps aux | awk '{sum +=$3}; END {print sum}'`" >> /tmp/cpu_`date +"%I%d%Y"`
echo "`date +"%D %T"` `ps aux | awk '{sum1 +=$4}; END {print sum1}'`" >> /tmp/mem_`date +"%I%d%Y"`

Script proves very handy when we need to check the CPU or Memory peak values. Just run it in cron for 1 min interval and you will start getting the values in text files from where you can figure out the peak values at a given point of time.

Thanks,

No offence, but why not go for a more complete monitoring solution like xymon, nagios, etc?
