Data Collection Rule : XPath queries to filter 7036 without WMI etc
Hi, In PowerShell on server I’m trying to filter out some events from Event Id 7036 Service Control Manager Start stop services. I’m trying to filter out WMI Performance Adapter, so I don’t want to have those events imported in log analytic workspace with data collection rule. Can you help me what I’m doing wrong ? $XPath = 'System!*[System[(EventID="7036")]] and [EventData[Data[@Name="param1"]!="WMI Performance Adapter"]]' Get-WinEvent -FilterXPath $XPath Get-WinEvent : Could not retrieve information about the Security log. Error: Attempted to perform an unauthorized operation.. At line:3 char:1 + Get-WinEvent -FilterXPath $XPath + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [Get-WinEvent], Exception + FullyQualifiedErrorId : LogInfoUnavailable,Microsoft.PowerShell.Commands.GetWinEventCommand Get-WinEvent : No events were found that match the specified selection criteria.

Log Analytics workspace:TimeGenerated value Current time for less than 48hrs logs(From current time)
In azure portal, In log analytics workspace, we have DCR Based tables, in which we have TimeGenerated field which we set as part of body and inject using folllowing python call- client.upload(rule_id=dcr_immutableid, stream_name=stream_name, logs=json.loads(body)) For TimeGenerated field which contains value less than 48hrs(from current time), for those logs it sets current timestamp. (It works for last 48 hrs TimeGenerated) Expected behavior should be TimeGenerated value should accept all values.
