Intune reporting with Log Analytics: control your Dell BIOS versions (uptodate or not)

3 A+ A-

In this post I will show you a Log Analytics report for BIOS versions for Dell devices (current installed and last one available on website).


The solution

This will resume in few steps:

- Creating a Proactive Remediation sript

- This script will be executed on your devices

- It will check some information

- It will send info to Log Analytics


This solution works with only one Proactive Remediation script, no need to use something else (EXE, Azure Automation, blob storage...)

The Proactive Remediation script will directly check on Dell website latest BIOS version available for the current model and compare it to the current one.


A big thanks to some guys who tested the solution as I don't have enough Dell models.

Thank you Peter, Omar, Mathias, Brahim, Ralph, Michel, Krzysztof, Mario, Coert, Benoit really appreciate your tests, community is awesome.


What show the report ?

- BIOS update status

- Devices countwith BIOS not uptodate (per model)

Auto update BIOS
You can find there a post I did about a solution to use a Proactive Remediation to: 
- Automatically detect if a BIOS is not uptodate
- Directly get latest version from Dell website
- Update BIOS


Get the files

Click on the below GitHub picture to get required below files:

- LA_DellBIOS_workbook.json

How it looks like ?

The Log Analytics will display below information:

- BIOS update status

- Devices with BIOS not uptodate (per model)

- Devices with BIOS not updated since (in days)

- Devices with BIOS older than 2 years

Those filters allows you to filter details on result on chassis, model or device name.




Then the tab contains some grid as below:

Damien, this is great! Got this working from devices from off the network. However, the script doesn't authenticated against proxy. Is that something easy to add? Have not done that from powershell myself.

Replying my own question. One line did the trick to use a default user:

[System.Net.WebRequest]::DefaultWebProxy.Credentials=[System.Net.CredentialCache]::DefaultCredentials

Got this to work in my environment with one issue. For some reason over half of my target collection is coming back with a status of "With Issues". When looking at the report it is only showing a total of 132 devices, but the group collection has over 300 Dell devices in it. What could be the issue here? Or is there a way to review logs on why the remaining devices are not being pulled to the report?
