Can't execute external script from zabbix

I'm trying to execute script from zabbix ui. I put my script to '/usr/lib/zabbix/externalscripts' folder. The script's name is "check_ssl.py". When I connect to server and go to that folder and execute the script manually - it works, but when I try to execute it from zabbix's ui - it throws an error :
"Traceback (most recent call last):
File "/usr/lib/zabbix/externalscripts/check_ssl.py", line 14, in <module>
ACCESS_KEY = conf('ACCESS_KEY')
File "/usr/local/lib/python3.8/dist-packages/decouple.py", line 243, in __call__
return self.config(*args, **kwargs)
File "/usr/local/lib/python3.8/dist-packages/decouple.py", line 105, in __call__
return self.get(*args, **kwargs)
File "/usr/local/lib/python3.8/dist-packages/decouple.py", line 90, in get
raise UndefinedValueError('{} not found. Declare it as envvar or define a default value.'.format(option))
decouple.UndefinedValueError: ACCESS_KEY not found. Declare it as envvar or define a default value."
ACCESS_KEY variable is declared and set as env. variable. Does anyone know why it throws this error?

The service environment is different from other users' env, see https://serverfault.com/questions/413397/how-to-set-environment-variable-in-systemd-service
Edit the service with systemctl edit zabbix-server and add Environment="ACCESS_KEY=your_access_key" in the [Service] section.

Create the script with Scope: Action Operation, Type: Script, Execute on: Zabbix agent (i've done it like that and works fine)
On commands insert the command, example python3 /home/suppor/python_scripts/customer/restart_apache.py
On Actions create one, select the condition (may be the trigger when to run the script), on Operation tab add the operation to run the script created
It works fine. You must allow remote commands on the zabbix agent

Executing other python scripts gives NameError exception

I have two .py scripts on the same folder, and I have a function like this on one:
def combat_menu():
exec("combat.py")
Theese scripts are named dungeon.py(the one im executing from) and combat.py.
When I execute this function this error appears:
Exception in Tkinter callback
Traceback (most recent call last):
File "C:\Users\hp\AppData\Local\Programs\Python\Python38-32\lib\tkinter\__init__.py", line 1883, in __call__
return self.func(*args)
File "C:\Users\hp\Documents\piton\Dungeon\dungeon_Data\dungeon.py", line 25, in combat_menu
exec("combat.py")
File "<string>", line 1, in <module>
NameError: name 'combat' is not defined
I execute this function from a tkinter button widget like this:
event_button = t.Button(root, text="Open CM", command=combat_menu)
I have tried importing the code, but this gives ImportError.

The exec() function supports dynamic execution of Python code. It is not executing a shell command. To execute a shell command, in your case calling another python file. Instead you can use for example:
os.system(*cmd*) ->
os.system('combat.py')

Python exclude CWD file in proc

I have a script called client that does a few things around the OS and it's failing when it comes to /proc/1/cwd
I'm trying to ignore these types of files but the script is still crashing when it comes to this file. I get Memory Map output and also a Stack Trace before the script crashes.
I did a file /proc/1/cwd command on the file and I can see it's a symlink, where I then included an if os.path.islink(file) is False: IF statement to skip it and proceed.
However, I seem to still be hitting it.
The below is the Traceback after the crash.
Traceback (most recent call last):
File "client.py", line 235, in <module>
File "client.py", line 120, in runner
OSError: [Errno 13] Permission denied: '/proc/1/cwd'
Failed to execute script client
The error suggests the script client is working on /proc/1/cwd and then right after seems to say that it can't execute itself?
Any help would be appreciated.
-----Additional -------
Code lines from error:
like 235 is literally the line runner(path)
runner() represents a function that has a for loop that cycles through files in a folder to find the correct file. During this process, runner will do the following:
do line 120 mode = os.stat(fullfilename).st_mode
check if os.path.isdir(fullfilename) is False:
then if stat.S_ISREG(mode) is True:
then if os.path.islink(fullfilename) is False:
then if fullfilename not in blacklist:
Line 120 is mode = os.stat(fullfilename).st_mode

I am having issues with using pynsist

Hi I've installed pynsist in order to make my python files into executables but I am having some issues. The project consists of two files that I've written. The main program to be run is Filereader.py and a supplied file called spuriousReq.py which Filereader.py uses a function from. Currently my installer.cfg file looks like this
[Application]
name=WFilereader
version=1.0
entry_point=Filereader
console=true
[Python]
version=3.4.0
[Include]
packages = matplotlib
statistics
bisect
files = spuriousReq.py
I've moved the installer.cfg file and both python files to the C:\Python34\Scripts folder in order to access them from the cmd (Yes I am new at this..). But I get the following error which I dont know how to interpret or solve..
C:\Python34\Scripts>"C:\Python34\python.exe" "C:\Python34\Scripts\\pynsist" inst
aller.cfg
Traceback (most recent call last):
File "C:\Python34\Scripts\\pynsist", line 3, in <module>

File "C:\Python34\lib\site-packages\nsist\__init__.py", line 393, in main
shortcuts = configreader.read_shortcuts_config(cfg)

shortcuts_config
appcfg = cfg['Application']
File "C:\Python34\lib\configparser.py", line 937, in __getitem__
raise KeyError(key)
KeyError: 'Application'

As mentioned in the documentation [http://pynsist.readthedocs.io/en/latest/] you need to specify the function from your 'Filereader.py' file which will be starting the execution of your script. For example if you have a 'main' function that will be the entry point or starting point of your script then you need to specify that in your 'installer.cfg' file like below:-
[Application]
name=WFilereader
version=1.0
entry_point=Filereader:main <------ Here mention your entry point function.
console=true
[Python]
version=3.4.0
[Include]
packages = matplotlib
statistics
bisect
files = spuriousReq.py

VirtualBox Python API - remote access

I'm trying to run virtual machine set on Computer with Windows 7 (my main laptop) from my netbook (Ubuntu system).
On Ubuntu I've prepared python script:
from vboxapi import VirtualBoxManager
import sys
sys.path.append("/home/myLogin/Downloads/sdk/bindings/webservice/python/lib")
mgr = VirtualBoxManager("WEBSERVICE", {'url':'myIP', 'user':'myServerLogin', 'password':'myPassthere'})
vbox = mgr.vbox
name = "Muszelek"
mach = vbox.findMachine(name)
session = mgr.mgr.getSessionObject(vbox)
progress = mach.launchVMProcess(session, "gui", "")
progress.waitForCompletion(-1)
mgr.closeMachineSession(session)
I'm getting error:
Installation problem: check that appropriate libs in place

raise ne
NameError: global name 'IWebsessionManager_logonRequestMsg' is not defined
Any idea how could I solve this issue?
Is it problem with libs on my Windows Machine?

I just had the exact same problem on my Mac. The issue is that VirtualBox_wrappers.py imports VirtualBox_client.py (which defines the global name in question) in a try block and continues (pass) if it can not be imported
try:
from VirtualBox_client import *
except:
pass
the issue is that VirtualBox_client.py depends on ZSI, which was not installed, so the import failed. Once I did
easy_install zsi
everything worked as expected.

It seems that the class is not found! Have you tried to look for the webservice api if they are available?
I had a similar issue, I looked in /usr/lib/virtualbox/sdk/bindings and I didn't find the webservice folder only xpcom was in there, so I just included the webservice folder from the sdk and all worked fine.
