Check Windows Safe Mode

[lpereira]

hello All:
We are facing regular issues in our remote location servers, after a power outage servers ramdonly start in "Safe Mode", and we do not know until we manually log in on them.

I'm wondering if there's a way to monitor if a server is in normal or safe mode and send the alert accordingly.

thanks in advance.

You can do this via WMI assuming you have networking on the machine:
https://docs.microsoft.com/en-us/window ... utersystem
https://serverfault.com/questions/43376 ... -safe-mode

Code: Select all

PS H:\> gwmi -Query "SELECT BootupState FROM Win32_ComputerSystem"


__GENUS          : 2
__CLASS          : Win32_ComputerSystem
__SUPERCLASS     :
__DYNASTY        :
__RELPATH        :
__PROPERTY_COUNT : 1
__DERIVATION     : {}
__SERVER         :
__NAMESPACE      :
__PATH           :
BootupState      : Normal boot

The check_wmi_plus plugin that ships with Nagios XI allows you to write custom WMI queries and load them as "plugins" under check_wmi_plus. It's a bit complicated though.

Or you could wrap the above execution in some Powershell and parse the BootupState property translating it to an appropriate status code for Nagios.

Thanks @mcapra This is even new one on me..

I wasn't sure that you could call WMI if server is in safe mode, usually machine has limited services operating.

Yeah, regarding remote WMI requests I think it would depend on what "flavor" of safe mode you're running in. If the request failed, at least you'd have that.

Locally executed Powershell should work regardless I would think? Never tried it myself.

Correct, for sure nothing would work if it was a "Network down" safe mode

Thanks Everyone for the responses.

I think the fastest and "easiest" way is to create a custom Powershell script, as mcapra suggested.

Once i have it created and tested will update the results.

Thanks, let us know how it comes out!
