Our "Popularity trends" report is not showing any results (0 views)

we have sharepoint server 2013 on-premises. and inside all our sites, the Popularity Trends report will show 0 views. so i checked the following:-

1. Central admin > Application management > Manage Service Application > "Usage and Health Data Collection Service Application", i found that it is stopped.

so i re-provision it, using this power-shell:-

$sap = Get-SPServiceApplicationProxy | where-object {$_.TypeName -eq “Usage and Health Data Collection Proxy”}
$sap.Provision()

and the service started again:-

but still the report will show 0 views.

so i read this link http://geekswithblogs.net/bjackett/archive/2013/08/26/powershell-script-to-workaround-no-data-in-sharepoint-2013-usage.aspx and when i run this script

$aud = Get-SPUsageDefinition | where {$_.Name -like “Analytics*”} 
$aud | fl 
 
$prud = Get-SPUsageDefinition | where {$_.Name -like “Page Requests”}  
$prud | fl 

i found that i have the "EnableReceivers" = False. so i run this script to enable it:-

if((Get-PSSnapin -Name Microsoft.SharePoint.PowerShell) -eq $null) 
{ 
    Add-PSSnapin Microsoft.SharePoint.PowerShell 
} 
$aud = Get-SPUsageDefinition | where {$_.Name -like “Analytics*”} 
# if analytics usage definition receivers is empty then manually add back receiver 
if($aud.Receivers.Count -eq 0) 
{ 
    $aud.Receivers.Add(“Microsoft.Office.Server.Search.Applications, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”, “Microsoft.Office.Server.Search.Analytics.Internal.AnalyticsCustomRequestUsageReceiver”) 
} 
# if analytics usage definition receiver is not enabled then enable it 
if($aud.EnableReceivers -eq $false) 
{ 
    $aud.EnableReceivers = $true 
    $aud.Update() 
} 
$aud | fl 
$prud = Get-SPUsageDefinition | where {$_.Name -like “Page Requests”}  
# if page requests usage definition receivers is empty then manually add back receiver 
if($prud.Receivers.Count -eq 0) 
{ 
    $prud.Receivers.Add(“Microsoft.Office.Server.Search.Applications, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c”, “Microsoft.Office.Server.Search.Analytics.Internal.ViewRequestUsageReceiver”)  
} 
# if page requests usage definition receiver is not enabled then enable it 
if($prud.EnableReceivers -eq $false) 
{ 
    $prud.EnableReceivers = $true 
    $prud.Update() 
} 
$prud | fl 

but still the report will show 0 view. although when i checked the following location C:\Program Files\Microsoft Office Servers\15.0\Data\Office i can see that there are files been generated and capture the user's actions :-

but i am not sure why those actions are not been reflected inside the "Popularity trends" report ? should i wait for couple of hours to have these actions reflected inside the "Popularity trends" report ?

Thanks
