Hello I have a question: how can I see the usage of the procesor when I play mp3? Which software I must install? Regards Boris ____________________ http://www.email.si/ |

Boris: The linux kernel publishes lots of usage information in the psuedo files in /proc/ and all the userland utilities I know of look there for their information so they can format it nicely. On most Linux systems the manual page for 'proc' contains descriptions of most of the useful files. Summary load averages are in /proc/loadavg : /proc/loadavg The load average numbers give the number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1, 5, and 15 minutes. They are the same as the load average numbers given by uptime(1) and other programs. Uptime is put on the stix in the current buildroot, busybox ps is is also there but it does not print out much. The classic utility for process by process timing statistics is 'top', but I do not see it in the buildroot. I would love to find a macro scale profiling utility that shows cpu usage over the lifetime of a process, but I may have to write it myself unless someone else on this list has one... A decent distribution agnostic introduction is here: http://www.redhat.com/docs/manuals/linux/RHL-7.2-Manual/ref-guide/s1-proc-topfiles.html and another longer one is here http://www.linuxforum.com/linux-filesystem/proc.html Boris Novak wrote: >Hello > >I have a question: how can I see the usage of the procesor when I play mp3? >Which software I must install? > >Regards > >Boris > >____________________ >http://www.email.si/ > > >------------------------------------------------------- >SF email is sponsored by - The IT Product Guide >Read honest & candid reviews on hundreds of IT Products from real users. >Discover which products truly live up to the hype.

There is a top utility included with BusyBox. If you edit gumstix_buildroot/source/busybox.config you find this line: # CONFIG_TOP is not set and change it to=20 CONFIG_TOP=3Dy then rebuild everything from scratch, then you should have a top command. You'll see quite a few other utilities that can be enabled as well. --=20 Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

As far as monitoring a process through its lifetime, sar and friends sort of do that for you. Or you can combine ps with rrdtool or something, depending on what you want to track. C |

"top" works pretty good, though it tends to consume a non-trivial amount of CPU itself, so you get heisenbergian effects potentially. C Boris Novak wrote: BN> Hello BN> BN> I have a question: how can I see the usage of the procesor when I play mp3? BN> Which software I must install? |
