Hi, I am unable to run your basic example “Sending emails with Python”  because nxlog is unable to load the required module.

Reducing the code to a minimal set, I found that nxlog is unable to load some basic Python modules that come bundled with the Python installation.

Following are some modules that nxlog is unable to load:

• smtplib
• socket
• ssl
• email.mime.text
• windows_tools.users (after installing with "pip install windows_tools.users")

Same file modified to be executed directly from python.exe in same machine, runs correctly

nxlog.conf:

Panic Soft
#NoFreeOnExit TRUE

define ROOT     C:\Program Files\nxlog
define CERTDIR  %ROOT%\cert
define CONFDIR  %ROOT%\conf\nxlog.d
define LOGDIR   %ROOT%\data

include %CONFDIR%\\*.conf
define LOGFILE  %LOGDIR%\nxlog.log
LogFile %LOGFILE%

Moduledir %ROOT%\modules
CacheDir  %ROOT%\data
Pidfile   %ROOT%\data\nxlog.pid
SpoolDir  %ROOT%\data


<Extension python>
    Module      xm_python
    PythonCode   'c:\Program Files\nxlog\modules\extension\python\py\send_email.py'
</Extension>

<Input in>
   Module    im_null
</Input>

<Output out>
   Module    om_null
</Output>

<Processor myprocessor>
    Module pm_null
    <Exec>
        python_call('main');
   </Exec>
</Processor>

<Route myroute>
    Path    in => myprocessor => out
</Route>

send_email.py:

import smtplib
#import socket
#import ssl
#import email.mime.text

# pip install windows_tools.users
#import windows_tools.users as users


import json
import nxlog

#def main():
def main(event):
    # Body that does nothing
    print("Hello from Main()")

nxlog.log:
