Re: [Fab-user] How to control paramiko logging level, when using fabric?

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 DEBUG
   Handler File '/home/xstack/git/installxstream/xsdeploy.log'
     Formatter <logging.Formatter instance at 0x1d17ef0>
   Handler Stream <open file '<stdout>', mode 'w' at 0x7f5e520a9150>
     Level DEBUG
   |
   o<--"paramiko"
   |   Level INFO
   |
   o<--"requests"
       Level INFO
       Handler <requests.NullHandler instance at 0x1b3e2d8>
       |
       o<--[requests.packages]
           |
           o<--"requests.packages.urllib3"
               Level NOTSET so inherits level INFO
               Handler <requests.packages.urllib3.NullHandler instance at 0x1b3e248>
               |
               o<--"requests.packages.urllib3.connectionpool"
               |   Level NOTSET so inherits level INFO
               |
               o<--"requests.packages.urllib3.poolmanager"
               |   Level NOTSET so inherits level INFO
               |
               o<--[requests.packages.urllib3.util]
                   |
                   o<--"requests.packages.urllib3.util.retry"
                       Level NOTSET so inherits level INFO

However 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.
