Hello,
See the output example at the end of letter. At the debug level I intended to display actual remote commands fabric is executing and their output, to help with any issues during debug.
There is no fabfile as such. This is python program, which does ton of stuff before starting executing any remote commands via Fabric.
>you have to definefabric.state.outputas stated in the docs
Can you be more specific as documentation does not provide any obvious way (for me). Meaning - setting like:
import fabric
import fabric.api
import fabric.network
.....
output['debug'] = False?
I am not a programmer, I just have to do some programming besides defining how to set environment properly. :) I would have left installer written in BASH as it was for the v1 if I did not have had to parse/create YAML config files.
Thank you

Hi Elvinas,
What kind of output do you want to supress? If you want only the commands run by your fabfile, hide everything but
running.Anyway, I think this code
fabric.api.hide('everything') fabric.api.show('running', 'user', 'output', 'stdout', 'stderr', 'warnings', 'aborts', 'status')doesn’t work as you expected. My advise, use a context manager on your fabfile to test it:
import fabric def your_task() with fabric.api.settings(fabric.api.hide('everything'),fabric.api.show ('running')): ... <your code> ...If you want to use this setting globally, you have to define
fabric.state.outputas stated in the docsRegards

Hello,
Unfortunately it does not. If I set globally (I suppose)
fabric.api.hide('everything')
fabric.api.show('running', 'user', 'output', 'stdout', 'stderr', 'warnings', 'aborts', 'status')
I still see this SSH noise. It is not coming from Fabric itself. It is paramiko, which somehow still catches global DEBUG level.
It is not critical, but it generates around 20 lines of noise output for 1 relelvant message, like
[10.193.31.52] run: [ ! -d /usr/local/share/xstream/puppet ] && mkdir -p /usr/local/share/xstream/puppet || true
And for less experienced users (which we intend to give this installer) such information line is lost :)
Thank you

Hi Elvinas,
read Managing output section in Fabric docs. I’m sure you will find what you need.
I use context managers to hide sensitive information:
with fabric.api.settings( fabric.api.hide('everything'), fabric.api.show ('running', 'user', 'output')):but you can configure it globally.
Hope it helps
Regards

Hello,
I am using Fabric to write our internal product deployment utility and having trouble supressing paramiko SSH output, when using DEBUG level. Is it possible to cut off messages like in the example below?
If I set global logging level to INFO, these messages are not printed, however it also hides debug level messages from the installer, which I want to print out.
I have tried to setup different levels of logging output.
if debug:
logging.getLogger('paramiko').setLevel(LEVELS.get('info', logging.NOTSET))
logging.getLogger('requests').setLevel(LEVELS.get('info', logging.NOTSET))
It seems to be set up properly, according to logging_tree (https://pypi.python.org/pypi/logging_tree) output:
Level DEBUGHowever at DEBUG level I still get tons of SSH connection noise, which is of no interest for out usage case. I am not intending to debug SSH connection, when enabling debug level for software product installer.
