Run Python 3.x script in alerts

[yashjain12yj]

I want to execute python 3 scripts when an alert is triggered.
Since Splunk default comes with python 2.x, but is there any way to convert it to python 3.x?

Can you try the below setup and see whether it works? The idea is to wrap your script within another python script so that when your script will run it will run using system python not splunk python. I have just given example of two different environments. You can modify the code related to platforms accordingly.

import os 
import subprocess
import sys

import logging
wrapped_script="<your actual script name>"


_SPLUNK_HOME=os.environ['SPLUNK_HOME']
_SPLUNK_PYTHON_PATH = os.environ['PYTHONPATH']
os.environ['LD_LIBRARY_PATH']='' #hack to stop splunk libries loading instead of system

if sys.platform == "win32":
    logfilename = 'searchcommand2_app.log'
    _APP_BIN_HOME=_SPLUNK_HOME + "<your actual script path>"
    _NEW_PYTHON_PATH = "<your python 3.x path>"
    os.environ['PYTHONPATH'] = _NEW_PYTHON_PATH
    my_process = _APP_BIN_HOME + "\\" + wrapped_script
elif sys.platform == "darwin" or sys.platform == "linux" or sys.platform == "linux2":
    logfilename = 'searchcommand2_app.log'
    _APP_BIN_HOME = _SPLUNK_HOME + "<your actual script path>"
    _NEW_PYTHON_PATH = "<your python 3.x path>"
    os.environ['PYTHONPATH'] = _NEW_PYTHON_PATH
    my_process = _APP_BIN_HOME + "/" + wrapped_script




logging.basicConfig(filename=logfilename, level=logging.DEBUG, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s')
mylogger = logging.getLogger("ourlogger")
mylogger.debug("wrapper: sys.argv=%s" % sys.argv) 



argstr=''
for thing in sys.argv:
    argstr=argstr + " " + thing

p = subprocess.Popen([os.environ['PYTHONPATH'], my_process, _SPLUNK_PYTHON_PATH ] + sys.argv[1:] , stdin=sys.stdin, stdout=sys.stdout, stderr=sys.stderr)
