SSRS Cache Schedule Re - powershell

Question

I have about ~50 reports that are scheduled to be "cached" on a recurring schedule (image below).
Is this information only available in Report Server Database or can the schedule information be retrieved using Powershell? All of the "obvious" methods I've run thus far (with powershell ise) either return no information or boolean values (all 'false')

Answer 1

You can use GetItemHistoryOptions to get the schedule for the report item.
Then based on the type of Item property of the ScheduleDefinitionOrReference [ref] parameter of the method, you can decide how to show the information.
Type of the Item, can be one of MinuteRecurrence, DailyRecurrence, WeeklyRecurrence, MonthlyRecurrence or MonthlyDOWRecurrence.
Example
For example to format MonthlyRecurrence you can use such code:
$svcUrl = 'http://the-host-name/ReportServer/reportservice2010.asmx'
$svc = New-WebServiceProxy -Class 'RS' -Namespace 'RS' -Uri $svcUrl -UseDefaultCredential
$reports = $svc.ListChildren("/", $true) | Where-Object { $_.TypeName -eq "Report" }
$KeepExecutionSnapshots = $false
$ScheduleDefinitionOrReference = New-Object RS.ScheduleDefinitionOrReference
foreach ($report in $reports) {
$result = $svc.GetItemHistoryOptions($report.Path,
[ref]$KeepExecutionSnapshots,
[ref]$ScheduleDefinitionOrReference)
if($ScheduleDefinitionOrReference.Item -is [RS.MonthlyRecurrence])
{
"'$($report.Name)' Schedule Information:"
"StartDateTime: $($ScheduleDefinitionOrReference.StartDateTime)"
"StartDateTime: $($ScheduleDefinitionOrReference.EndDate)"
"EndDateSpecified: $($ScheduleDefinitionOrReference.EndDateSpecified)"
"Days: $($ScheduleDefinitionOrReference.Item.Days)"
$months = Get-Member `
-InputObject $($ScheduleDefinitionOrReference.Item.MonthsOfYear) `
-MemberType Property | Where-Object {
$ScheduleDefinitionOrReference.Item.MonthsOfYear.$($_.Name) -eq $true
}
"Months:$($months.Name -join ",")"
}
}
And the result will be something like this:
'MyReport' Schedule Information:
StartDateTime: 12/19/2017 18:00:00
StartDateTime: 01/01/0001 00:00:00
EndDateSpecified: False
Days: 1,3-5
Months:August,December,July,November,October,September
