CPU Bash Multi Core Monitor

I was not able to find a correct solution for CPU utilization. I adopt a CPU monitor in bash to output Nagios format. At this moment it checks the avg CPU load (sum of % usage of each core and divided by the number of cores) I am using nagios v4.4.6, but as I saw probably it will work also with the previous version. usage: ./custom_cpu.sh {warning} {critical} example ./custom_cpu.sh 10 20 output: OK total CPU usage: 3%|cpu0=3.66667 cpu1=3.34448 cpu2=3.65449 cpu3=5.29801 cpu4=3.32226 Inside the code we are doing a sum of all cores values and dividing it by the core amount. I have no ide why images are not working, hopefully it will work soon.
