Passing a parameter from bakery to Windows local check

Checkmk Dev&Exchange
1

I apologize up front if this has already been answered, but I tried searching the forums and I’m not what keywords to use to find the results. I have a custom check that I built but I need a bakery rule to control what directory it is using when performing the local check. I have the bakery rule configured to make an entry on the hosts “check_mk.bakery.yml” file, so I feel I have everything configured on the checkmk side, but I’m unsure how to pull that information into my check when it runs in Windows. I see in a Linux check you can do a conf.get(“varname”), is there something similar to pull in the variable using PowerShell?

Here are some snippets from my configuration

WATO Bakery Config File

def _valuespec_tmp_directory():
    return Dictionary(
        title=_("Temp File Count (Windows)"),
        help=_("This will deploy my example plugin."),
        elements=[
            ("tmpdirectory", TextAscii(
                title=_("Directory to monitor the count of temp files"),
                allow_empty=False,
            )),

Bakery File

class TmpDirectoryConfig(TypedDict, total=False):
    interval: int
    tmpdirectory: str

def get_tmp_directory_windows_config(conf: TmpDirectoryConfig) -> WindowsConfigGenerator:
    yield WindowsConfigEntry(path=["tmp_directory", "tmpdirectory"], content=conf["tmpdirectory"])

Host check_mk.bakery.yml File

global:
  enabled: true
  install: true
  port: 6556
tmp_directory:
  enabled: true
  tmpdirectory: C:\Windows\Temp

I could just use PowerShell to scrape the information out of the “check_mk.bakery.yml”, but this didn’t feel like the right path. Thanks for any advice!

One of my Windows plugins needs a config file.
The link shows the bakery plugins that deploys the plugin and the config file.

The WATO rule can also be found in this repository.
This config file is than used by the powershell script uses as plugin.

Thank you @andreas-doehler, this looks like what I need to dig into.
