How to get a log for Microsoft Cloud Service (Intune) synchronization activities ?

[Glenn_Gagne]

We are testing to intergrate the Intune scan in our On-Premise Lansweeper following the recommended method with Microsoft Cloud Service using Graph.

I started an initial sync, pressing the "Scan now" button. After that, the button is grayed and say: "In scanning queue". In the Scanning Queue window, I don't see nothing telling me something is in work... I just see "IP Scanning and Windws computer scanning" sections with "Processing and In queue" at 0 state... No section about "Intune/MDM or other scanning methods could help me to understand what happen. The scan is running since over 2 hours and no new assets, no error, no information to help me.

On the Microsoft Azure side, under Graph I can confirm a connection was happen three times from the client ID dedicated for Lansweeper sync.

Can I have an advanced log file somewhere to help me. ?

As suggested, I would work with support on this item. Essentially you will need to enable debug logging for the Azure AD sync (or InTune or MS365), after which more detailed information will appear in the errorlog (typically %ProgramFiles(x86)%\Lansweeper\Service\errorlog.txt). Support will be able to provide you with a DebugOptions.xml file that will provide the correct parameters for debugging.

Here's an excerpt showing the beginning of an AzureAD scan (identifying information has been obfuscated). This is from a v10 install, before Lansweeper started using the EntraID naming:

It can take a while; I've seen it take up to four hours to complete an Azure AD sync for us, although typically it completes within an hour or two. It also seems to be a somewhat resource intensive process on the collector side.

Hi ErikT,

I understand, if I need these kinds of logs, I will need Lansweeper support. No straight way to get these logs ?

Finally, after 3 hours I got the data from Intune. The sync is working fine.
