Noise Budgetter

Users manual

Manual

• It plots DARM displacement signal from K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQ, i.e. it plots PROC_DARM*(dewhitening filter).
• Management commands

  k1script1> sudo supervisorctl start noiseb   # <- Start NoiseBudgetter
  k1script1> sudo supervisorctl stop noiseb    # <- Stop NoiseBudgetter
  k1script1> sudo supervisorctl restart nosieb # <- Restart NoiseBudgetter
  k1script1> sudo supervisorctl status noiseb  # <- Check run status
  k1script1> sudo supervisorctl tail noiseb    # <- Check error log

Trouble shooting

• If NoiseBudgetter returns some error, please check application processes on k1script1.

  • Running only 2 processes is the correct situation.

    k1script1> ps -ef | grep [m]anage
    controls  1223   771  0 Jan29 ?        00:00:00 python3 manage.py runserver 0.0.0.0:8000
    controls  1343  1223 11 Jan29 ?        2-21:58:41 /home/controls/miniconda3/envs/noiseb/bin/python3 manage.py runserver 0.0.0.0:8000

• If more than 2 processes are running, please kill all once and relaunch.

  k1script1> sudo supervisorctl stop noiseb
  k1script1> pkill -KILL manage.py
  k1script1> sudo supervisorctl start noiseb

Developers' manual

• Currently running on k1script1 k1ctr7 (because k1ctr7 has the vertual environment.)

• The server is running in the environment 'noiseb'. 'django-env.'

• The scripts are in /users/yuzu/noiseb/DjangoApp /kagra/Dropbox/Personal/Shoda/src/AppTest/

  • The code is uploaded on github.

Software management

Noise Budgetter is managed by supervisord on k1script1. Basically, applications managed by supervisor are automatically launched when k1script1 boots up and they are automatically re-launched when they hang up.

• If you update NoiseBudgetter code, please restart the process by following command.

    k1script1> sudo supervisorctl restart noiseb

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

    k1script1> cat /etc/supervisor/conf.d/noiseb.conf
    [program:noiseb]
    user=controls
    directory=/users/yuzu/noiseb/DjangoApp
    command=bash -c 'source /kagra/apps/etc/conda3-user-env_deb10.sh && conda activate noiseb && python3 manage.py runserver  0.0.0.0:8000'
    autorestart=true
    autostart=true
    redirect_stderr=true
    stdout_logfile=/tmp/superv_noiseb.log

What's new

• Sum of the all noise will be plotted together. (2019/11/12)

Old information

Users manual

• It plots DARM displacement signal from K1:CAL-CS_PROC_DARM_DISPLACEMENT_DQ, i.e. it plots PROC_DARM*(dewhitening filter).
• If crashed, go to k1ctr7 and run from a button on the medm screen or commands below:
