Problem: zipped Python module

During the registration of the Check_MK Updater on Windows, you may face this issue:

Code Block

language	powershell
theme	RDark

C:\Program Files (x86)\checkmk\service>check_mk_agent.exe updater -vv
       You must install Python Module to use the updater with parameters '-vv'. 
       To install Python Module you should use Bakery.

Note
Please make sure that you open the cmd/PowerShell as an administrator!

The problem is that the Python module either was not successfully unzipped during the updater process:

Or the folder is completely empty

A possible workaround

If you have only a python_x.cap file

For some reason, you may have only one python_x.cap file in your folder. In that case, you have these two options:

Reinstall the Python (if the folder is zipped)

Code Block

language	powershell
theme	RDark

mkdir C:\ProgramData\checkmk\agent\modules\python-3 & expand C:\ProgramData\checkmk\agent\install\modules\python-3.cab -F:* C:\ProgramData\checkmk\agent\modules\python-3 && cd C:\ProgramData\checkmk\agent\modules\python-3 && call postinstall.cmd

Reinstall the Python (if the folder is empty)

Code Block

language	powershell
theme	RDark

expand C:\ProgramData\checkmk\agent\install\modules\python-3.cab -F:* C:\ProgramData\checkmk\agent\modules\python-3 && cd C:\ProgramData\checkmk\agent\modules\python-3 && call postinstall.cmd

Reinstall the Python (if the folder is zipped)

Code Block

language	powershell
theme	RDark

mkdir C:\ProgramData\checkmk\agent\modules\python-3.8 & expand C:\ProgramData\checkmk\agent\install\modules\python-3.8.zip -F:* C:\ProgramData\checkmk\agent\modules\python-3.8 && cd C:\ProgramData\checkmk\agent\modules\python-3.8  && call postinstall.cmd

Reinstall the Python (if the folder is empty)

Code Block

language	powershell
theme	RDark

expand C:\ProgramData\checkmk\agent\install\modules\python-3.8.zip -F:* C:\ProgramData\checkmk\agent\modules\python-3.8 && cd C:\ProgramData\checkmk\agent\modules\python-3.8  && call postinstall.cmd

Solutions

Increase the timeout of the updater

Via bakery

Go to Setup → Agents → Windows, Linux, Solaris, AIX → Agent rules → Set timeouts for plugins and local checks

Script Pattern: cmk_update_agent.checkmk.py

After saving the rule, you must bake and sign the new agent!

Here we described in detail how to configure caching and timeout for Windows plugins: Asynchronous execution of Windows plugins.

Via config file

Code Block

language	powershell
theme	RDark
title	C:\ProgramData\checkmk\check_mk.user.yml

plugins:
enabled: true
execution:
cache_age: 86400
pattern: $CUSTOM_PLUGINS_PATH$\cmk_update_agent.checkmk.py
timeout: 180

Create an exception for the AV

Please create an exception for the following paths for the AV:

Code Block

language	powershell
theme	RDark

C:\ProgramData\checkmk
C:\Program Files (x86)\checkmk

Reinstall python

Code Block

language	bash
theme	RDark

:: Reinstall Checkmk Python module for Windows agent
@echo off
if not exist "%ProgramData%\checkmk\agent\install\modules\python-3.8.zip" (
echo "%ProgramData%\checkmk\agent\install\modules\python-3.8.zip" is absent, impossible to reinstall
exit  /b 1
)
cd %ProgramData%\checkmk\agent || echo "Windows agent is not installed" && exit /b 11
net stop checkmkservice
mkdir modules\python-3.8
cd modules\python-3.8

call postinstall.cmd
net start checkmkservice
