CPU use is excessive

SOlution inspired from link in bottom

Make a new service

It should contain the command in square brackets [while true; do (echo “%CPU %MEM ARGS $(date)” && ps -e -o pcpu,pmem,args --sort=pcpu | cut -d" " -f1-5 | tail) >> /var/log/ps.log; sleep 5; done]

Save it and start it, or reboot to see if starts (and check how it looks)

You’ll have the log in /var/log/ps.log

My newb inspiration command line - How to log CPU load? - Ask Ubuntu

Hope that helps.
