Cpu Temp And Usage For Mac
How can I get CPU usage for process if i know only PID? MAXOS X I looked through top utility source codes for MACOSX and I have found several important functions in libtop.c /.
Iterate through all processes and update their statistics./ libtoppproctableread(booleant reg) libtopptaskupdate /. Get CPU usage statistics./ libtoppinfoupdatecpuusage The problem is that I don't understand how they get%CPU usage from this huge amout of MACOS specific 'mach kernel' system calls. Does anybody have solution for this? I the source they get systemtime, usertime, totaltime. I totaltime is time from process start or what?

For example my results: for Opera Browser: pid:1214 user:653.517582sec system:193.597306sec total:847.114888sec Correct info from top utility: PID COMMAND%CPU TIME 1214- Opera 8.0 14:04.52 I dont understand how to convert my results to 8.0%. Total time here is a sum of user time and system time. Total time is correct: 847sec is approx 14min 04 sec To get cpu usage percent i need something like idle time for all process. I have already spend the whole day but without any advance.

Look at how implements sorting by CPU usage. Totaltime - ptotaltime gives the CPU time used by the process over the last sampling interval. Divide this by the sum of this difference for each process and you've got your percent. BTW, while using Mac OS X on your Mac to read Mac OS X documentation and Mac OS X source code, you may have noticed that they consistently spell it 'Mac' and 'Mac OS X'. You probably thought they just misspelled the name of their own OS a couple million times, but in fact, as strange as it may sound, 'Mac OS' is the correct spelling, not 'MACOS'. Mac is not an acronym.
I read the topic of MacBook Pros overheating since SL and was wondering what all those people are using to check their CPU temperature. Like so many others I also have noticed my MBP runs hot now but it is not really a problem because I have always used a small electric fan aimed at my Macs, AirPort Extreme Base Station, and ViewSonic LCD display to help keep them relatively cool especially in Summer ( the base station gets really hot ). So if there is some utility for checking temperature that does not interfere with the system I would like to try it out.
