I have some processes running on Debian that I want to limit cpu of it usage in the "soft" manner. For example, if it eats more than 70% of a single core for more than 15 minutes, the CPU should be limited to 30%. If it uses only 30-40% of a single core, it is free to run.
Currently, I have to manage it by logging into the server and do the work manually. Therefore, I am thinking to automatic this tasks by some script/software and crontab. Any suggestions are highly aprreciated.
