Are audit logs in SharePoint Server collected for events on attachments?


I only see entries with type “Update”. Should other types of events also be recorded? Is this normal SharePoint behavior?

I use this PowerShell to check what kind of events I have on the attachments:

$s=Get-SPSite https://sharepoint/  
$q=New-Object Microsoft.SharePoint.SPAuditQuery($s)
$s.Audit.GetEntries($q) |? DocLocation -Like '*Attachments*'
