As of my knowledge Linux system load average is affected by any means that can affect the system like CPU resource usage, memory consumption, disk I/O, network I/O etc. In top command I am checking the impact of running a python program on the system.
PID USER PR NI VIRT RES SHR %CPU %MEM TIME+ COMMAND 13895 ayush 20 0 61.1m 12.6m 6.1m 2.9 0.2 0:06.92 python sys_stat_monitor.py
So it is showing the program has utilized only 2.9% of the CPU time assigned by the CPU to the program to complete its execution. So should I assume this application affected the system by 2.9% in terms of CPU resource consumption at that particular moment??
