SharePoint Online URLs / Site Names Not Showing Correctly

Actually we use that DataSource too and I see the same issue. So I looked at the code and it's just calling the getSharePointSiteUsageDetail (7 day) GraphAPI and retrieving some raw CSV data. The report data looks screwed up to me though. Like all the Site IDs are "00000000-0000-0000-0000-000000000000" and the URLs, Owner Display Name and Owner Principal Name are long HEX codes. I don't have admin to O365 to check directly but I'm wondering if something is broken in the report and how long it's been like that.

As a general troubleshooting test I suggest you look at the DataSource (Office365_Reports_SharepointOnlineSiteUsage) in Settings > LogicModules > DataSources, then use the Test Active Discovery button. Check what it shows for instances there and if the names look correct. If it shows correctly there then I would just delete all the instances then get Active Discovery to rebuild it. Note that this will cause you to lose any historical data for sharepoint site usage, but since it sounds like it never worked until just now, so I assume that is ok to do. If the test still shows GUIDs then you might need to dig into the powershell code or work with LM support if it's not by design.

Yeah I spoke to support today - this is very much not good.  Makes the entire monitoring tool for SharePoint useless.

Support said: "This is the response we see from Microsoft showing the GUID as the name rather than the site.  We pull this data from a CSV generated within the O365 environment, so if the names in that CSV are the GUIDs we would expect them to show up here as GUIDs"

What's very interesting is that it used to work just fine.  Initially we were able to poll the data, and then we accidently changed collectors to use one of our Linux collectors and didn't realize that broke it.  We set the collector back and then it suddenly  updated all our sharepoint sites with these GUIDs ? 

So yes, Microsoft has changed something.  LogicMonitor is using the Reporting module in GraphAPI to "getSharePointSiteUsageDetails" which is served by the Usage Reporting data in Microsoft 365 admin center.  Even that data is completely masked on purpose.  I have a feelign Microsoft changed this.  So now you have to explicity tell your tenant to allow this type of data to be visible within reports.  Info here: https://docs.microsoft.com/en-US/microsoft-365/admin/activity-reports/activity-reports?view=o365-worldwide#show-user-details-in-the-reports

I am trying this now and will report back....

Ok - that fixed it.  I think Microsoft may have changed something automatically at some point.  

FIX: go to admin.microsoft.com, sign in as global admin, go Settings > Org Settings > Reports

Uncheck the box "Display concealed user, group, and site names in all reports

This fixed the names in LM as well.

Did a little digging and found this....looks like Microsoft decided to pseudonymize user-level info starting 9/1/21.  They announced this on 8/30/21 (LOL!).
