CPU Usage

    Hi,

    i just installed airtime 1.8.1 on my debian squeeze 64bits dedicated server (deb from your repository).

    I configured it to be used with icecast2, with both mp3 and vorbis stream.

    I got an average 20% CPU usage for PYPO, even when Airtime doesn't play and with icecast2 stopped.

    Here's a piece of my ps -faux return :

    USER       PID %CPU %MEM    VSZ   RSS STAT START   TIME COMMAND
root      1716  0.0  0.1   3944   440 S    10:55   0:00  \_ svscan /etc/service
root      1718  0.0  0.1   3772   384 S    10:55   0:02  |   \_ supervise pypo
pypo     28809 19.0  0.0      0     0 Z    12:02   0:00  |   |   \_ [python] <defunct>


    It seems a bit cpu expensive !

    Is it normal ? The Zombie status on pypo is normal too ?
    What can i do to reduce this ?

    I installed everything between yesterday and today (18 mars 2011)
    so i guess i have everything up to date..

    Thanks !

    Best Regards,

    Thomas

    hi Thomas,

    first of all try to reboot the server.
    [python] <defunct> could be possible in case new installation or re-installation pypo services.

    hmm, I have several installed airtime instances on ubuntu 10.10 64-bit w/o any issue
    Please, look at /var/log/airtime/pypo/current log for any errors

    if i well analyse the error, it seems that he try to contact http://localhost:80/api/version/api_key/%%api_key%%

    but for sure there will be no answer at this adress as i configured a virtual host for Airtime !
    (my server is also a http webserver hosting different domains an applications)

    By digging a bit i founded /etc/airtime/pypo.cfg and i changed the base_url with the good one for me : 'radio.airlab.fr'

    -> did i miss something so that happened ? or is it just a forgot in your documentation ?


    I have reboot the server,
    now pypo found Airtime version (1.8.1) and is happy as he is compatible with this version.

    BUT, i have now a new error in the pypo log, that i can not understand Very Happy

    ok, seems the apache server conf is fixed.
    The error "socket.error: [Errno 111] Connection refused" says that RabbitMQ is not accessible. Check it.

    How do i now if rabbitMQ is running ?

    i got this in my pypo.cfg conserning rabbitMQ

    rabbitmq_host = 'localhost'
    rabbitmq_user = 'guest'
    rabbitmq_password = 'guest'

    do i have to fix the host the same way i did for pypo (by replacing localhost with radio.airlab.fr ?)
    or localhost is ok for this app ?

    i don't know what i have to look for, actually i don't even know what rabbitMQ is Smile

    Thanks !

    i also just tried to update my station info in Airtime,

    and a little error just appeard on top (after a long lag) :

    Warning: fsockopen(): unable to connect to 127.0.0.1:5672 (Connection refused) in /var/lib/airtime/library/php-amqplib/amqp.inc on line 376

    guess 5672 is the rabbitmq port !

    i'll try to open it in my iptables...
