Howdy All,
To give an overview of the problem,
I have an installer. It is used to install virtual machines at
specific location.
The installer is written in Powershell and Python. The topmost script
is in
Python ( install.py ) which internally calls other .py and .PS1 (
powershell ) scripts using popen() .
I am working on having a file based logging mechanism for this
installer. i.e both for .py and .PS1 scripts.
Q1. I want to use python logging module. But then how do I integrate
it with powershell scripts. ?
One option would be to write into a .log file using logging module in
all .py scripts. Use that ( .log ) file
in powershell scripts by using its own logging module ( dnt knw if it
exists ! )
Q2. Can we call / run .py from inside .PS1. ?
Please suggest suitable methods for effective logging mechanism.
Thanks

PowerShell has built-in cmdlets for logging that use the verb "write".
Running the command "get-command write*" will list those commands for
you (and a couple of other ones). Each one is controlled by a shell
variable that ends with "Preference". For example, to turn the warning
messages up, then set the variable $WarningPreference to "Continue".
Other options are Stop, Inquire, and SilentlyContinue. To turn down
logging, set each of the $*Preference session variables to
"SilentlyContinue". To turn up logging, then set them all to "Continue".
Here are some references for automatic logging [1] and a script template
with a logging function [2]
