Office 365 monitoring

This is unofficial...On my own and on the side, I designed a DataSource to monitor Office 365 using Microsoft's API. See more on my blog  All the usual disclaimers apply...use at your own risk. I will try to help if it doesn't work for you.

  • Hi Mike, The customer wants the O365 Audit logs monitored and a report to be submitted daily. What we currently have now is a powershell script that pulls out a csv with relevant security events. We then present a daily report based on these events. It is a bit labor intensive and I think we can use LM to automate it. I'm trying to develop a PS script to embed in a datasource to search this audit log at set intervals. If I can have LM pull these events in (not too worried about the alerting for now) I can then create a dashboard & reports. When you say test on my account, do you mean the O365 a/c? I dont have anything in LM yet as I'm still cooking a PS script to do what I need.

    This is what I am currently using to pull events for the previous 24 hours.


    $CreateEXOPSSession = (Get-ChildItem -Path $env:userprofile -Filter CreateExoPSSession.ps1 -Recurse -ErrorAction SilentlyContinue -Force | Select -Last 1).DirectoryName
    . "$CreateEXOPSSession\CreateExoPSSession.ps1"
    Connect-EXOPSSession -UserPrincipalName

    #Output files directory
    $outputFile = "C:\Users\john.doe\Desktop\AuditRecords.csv"

    # Set Dates
    $StartDate = (Get-Date).AddDays(-1)
    $EndDate = (Get-Date)

    $AlertOperations = @('FileDeletedFirstStageRecycleBin','FileDeletedSecondStageRecycleBin',...............................................LOTS MORE!!!!)

    Search-UnifiedAuditLog -StartDate $StartDate -EndDate $EndDate -Operations $AlertOperations -ResultSize 5000|epcsv $outputFile -NoTypeInformation -Append
