The calculations provided by the tool are recommendations and not requirements and can be changed in the configuration file described below. The tool then calculates at what levels you should be setting your stress levels in the ControlUp Console based on actual data from your own ControlUp monitored environment. You import your ControlUp monitoring data from Insights and from the console into the tool. The Stress Levels Calculator is a tool that you access from the ControlUp script library.

Unless you have a valid reason to do this, you’re better off not randomly running “yes”, since it obviously causes performance issues until it stops running.įor some assistance, the video below demonstrates the entire process from start to finish:įor those wondering, this works in all versions of Mac OS X and even linux as well, so you can stress test any Mac ever made this way. If not, there’s probably a typo in there somewhere. You’ll also see all instances of “yes” drop from the process list in Activity Monitor. When finished, in the same terminal window type “killall yes” into the command line to kill all instances of the yes command.
You’ll quickly discover in Activity Monitor or top that the processor is getting hit hard. Yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null & Either repeat the process by hitting up arrow and return to run another several instances, or throw a group onto a single line like so: That sends one instance of ‘yes’ into the background, but to load up the CPU you’ll want to have more than one running. When ready to stress test the Mac, type the following command: To begin, launch Terminal, and you may want to watch the UI-based task manager Activity Monitor so you can easily observe the CPU load and system resources. This means if you have a dual core Mac with a hyperthreaded processor, you’ll need to have at least four different instances of “yes” running to put full load onto the CPU. Generally speaking, each instances of “yes” will max out a single thread on a single CPU core. To max out the Mac CPU we’ll use the command line tool called “yes”, which basically does nothing except repeat the word “yes” at such speed that it consumes all available processor resources.
