Happy Function Generator

Software management

Happy Function Generator is managed by supervisord on k1script. Basically, applications managed by supervisor are automatically launched when k1script boots up and they are automatically re-launched when they hang up.

• If you update happy function generator code, please restart the process by following command.

    k1script> sudo supervisorctl restart als_freqmon_xpll # <- freqmonitor_XPLL.py
    k1script> sudo supervisorctl restart als_pcas_xpll    # <- pcas_xpll.py
    k1script> sudo supervisorctl restart als_freqmon_ypll # <- freqmonitor_YPLL.py
    k1script> sudo supervisorctl restart als_pcas_ypll    # <- pcas_ypll.py

• Configuration file for supervisord (Maybe it is not needed to touch for many people.)

    k1script> cat /etc/supervisor/conf.d/k1als.conf
    [program:als_freqmon_xpll]
    user=controls
    directory=/home/controls
    command=bash -c 'source /kagra/apps/etc/client-user-env.sh && \
      python /opt/rtcds/userapps/release/cds/common/scripts/epics-motor- control/keysight/freqmonitor_XPLL.py'
    autorestart=true
    autostart=true
    stopasgroup=true
    redirect_stderr=true
    stdout_logfile=/tmp/als_freqmon_xpll.log
