- Thread-topic: looking for System APIs for load monitoring
I am developing an application that needs to monitor the system's
CPU and IO load while it's running to be able to identify a low
system load and only do it's resource-hungry work while the system
is not busy doing other things. I've been searching for the low-level
system API that would give me access to this kind of information but
i have not yet found exactly what i need - functions like
host_processor_info supply the overall CPU usage which is nice, but i need
to know the CPU usage of each individual process. The kind of information i
need is essentially what's supplied by the ps -axv command. But i don't want
to solve my problem by calling ps as an external task - i am sure there is
a more elegant way to get the info directly. Could anybody help me by
pointing me to some source of documentation (maybe i am stupid or looking in
the wrong place but i did not find the info in the documentation supplied
with Xcode) and/or maybe some code examples.
thanks a lot
P.S.: My apologies if this question is not exactly Cocoa-related...
