I am relatively sure this is quite easy to do but my google fu is not running strong
At the moment I am doing:
add-pssnapin windows.serverbackup
get-wbsummary
This returns me:
NextBackupTime : 07/09/2012 12:00:00
NumberOfVersions : 210
LastSuccessfulBackupTime : 06/09/2012 21:00:13
LastSuccessfulBackupTargetPath : \\?\Volume{bf315689-e5ed-11e1-a376-d067e5f384ea}
LastSuccessfulBackupTargetLabel : SBSERVE 2012_08_21 12:20 DISK_01
LastBackupTime : 06/09/2012 21:00:13
LastBackupTarget : SBSERVE 2012_08_21 12:20 DISK_01
DetailedMessage :
LastBackupResultHR : 0
LastBackupResultDetailedHR : 0
CurrentOperationStatus : NoOperationInProgress
What I want to do is get just the result portion (not its title into a variable) so for example $lastbackuptime = 07/09/2012 12:00:00
PS> $wbs = Get-WBSummary
PS> $lastbackuptime = $wbs.NextBackupTime

In powershell I'm using
(Get-Timezone).BaseUtcOffset
to get the UTC offset of a computer which gives me +1h for my timezone. That is technically correct since I'm in CET in winter (UTC+1) and CEST in summer (UTC+2). Right now tho it is DST, so CEST (UTC+2) for me so I'm wondering how I could get this information in powershell since the above command tells me that my timezone is UTC+1 and doesn't mention DST at all.
As a workaround I currently use
$date = Get-Date
($date - $date.ToUniversalTime()).TotalMinutes
to get the offset from UTC of my timezone with DST. It evaluates to +120 minutes which is exactly what i need.
Output of Get-Timezone:
Id : W. Europe Standard Time
DisplayName : (UTC+01:00) Amsterdam, Berlin, Bern, Rom, Stockholm, Wien
StandardName : Mitteleuropäische Zeit
DaylightName : Mitteleuropäische Sommerzeit
BaseUtcOffset : 01:00:00
SupportsDaylightSavingTime : True
Output of $date - $date.ToUniversalTime():
Days : 0
Hours : 2
Minutes : 0
Seconds : 0
Milliseconds : 0
Ticks : 72000000000
TotalDays : 0,0833333333333333
TotalHours : 2
TotalMinutes : 120
TotalSeconds : 7200
TotalMilliseconds : 7200000
Yes, you can use the static method IsDaylightSavingTime on the TimeZoneInfo class to get this information from a desired DateTime:
$now = [DateTime]::Now
[System.TimeZoneInfo]::Local.IsDaylightSavingTime($now) # Returns $True or $False
thank you Bender the Greatest you got me on the right path. The class System.TimeZoneInfo has a function that does what i want:
[System.TimeZoneInfo]::Local.GetUtcOffset((Get-Date)).TotalMinutes
gives me +120 minutes

I have an internal web app that provides connection statistics. I am trying to use PS to collect those statistics, which are in .conent. The .content property has a lot of other values I am trying to filter out and I haven't been very successful.
My Command:
invoke-webrequest -URI http://<my internal web site> | Select-Object -ExpandProperty Content
Returned Results:

They only line I care about is "Current Active Sessions: 6" and really all I care about is the numerical value which I will use in a test later in the script.
How can I just grab the one value I need?
$iwr=invoke-webrequest -URI http://<my internal web site> |
Select-Object -ExpandProperty Content
$cas=$iwr -split [System.Environment]::NewLine |
Select-String -Pattern "Current Active Sessions:\s*(.*)"
$cas.Matches[0].Groups[1].Value
Above code snippet should return 6. Tested using the following (constant) value of $iwr instead of invoke-webrequest:
$iwr=#'

I need to extract an alerts from rest api and sent it to a file with powershell
I was able to extract the alerts outputs looping the xml file:
foreach ($c in $temp){$c.timeOfAlertFormatted,$c.parent,$c.child,$c.category,$c.servicePlanDisplayName,$c.message}
Thu 09/19/2019 12:00:19 AM
IL
Servername

One or more source luns do not have a remote target specified/mapped.

One or more source luns do not have a remote target specified/mapped
I am new to PS , what i want to achieve is to add descriptive string
to each filed, i.e:
Time: Thu 09/19/2019 12:00:19 AM
Country: IL
Server: servername
etc ,the rest of the fields.
i tried :
foreach ($c in $temp){Write-Host "Time : $($c.timeOfAlertFormatted)"}
Time :
Time :

Time :
Time :
Time : Thu 09/19/2019 12:00:19 AM
its printing empty "Time" fields
here is example of the xml:
It looks like you have already loaded the xml and filtered out the properties you need in a variable $temp.
I think what you want can be achieved by doing:
$temp | Select-Object #{Name = 'Time'; Expression = {$_.timeOfAlertFormatted}},
#{Name = 'Country'; Expression = {$_.parent}},
#{Name = 'ServerName'; Expression = {$_.child}},
Category,ServicePlanDisplayName, Message
The above should output something like
Time : Thu 09/19/2019 12:00:19 AM
Country : IL
ServerName : Servername
Category : Phase Failure
ServicePlanDisplayName : Gold
Message : One or more source luns do not have a remote target specified/mapped.
Time : Wed 09/18/2019 02:18:25 PM
Country : IL
ServerName : Server2
Category : General Failure
ServicePlanDisplayName : Gold
Message : One or more source luns do not have a remote target specified/mapped.
If your variable $temp is NOT what I suspect it to be, please edit your question and show us the XML aswell as the code you use to extract the alerts from it.

Windows 2016 slower now 48 times! :)
In Windows 2016 Meltdown/Specter fixes are disabled.
Is there any option for improving the performance of powershell commands in Windows 2016?
Thanks.
Well, I found another solution. It's using bottlenecks through WMI.
The WMI msvm-ethernetswitchport class can provide all the VMSwitches elements, where we can already get the same information that Powershel CMD Get-VMSwitch provides.
https://learn.microsoft.com/en-us/windows/desktop/hyperv_v2/msvm-ethernetswitchport and etc.
A simple example:
ManagementScope scope = new ManagementScope("\\\\.\\ROOT\\virtualization\\v2");
ObjectQuery query = new ObjectQuery("SELECT * FROM Msvm_EthernetSwitchPort");
ManagementObjectSearcher searcher =
new ManagementObjectSearcher(scope, query);
ManagementObjectCollection queryCollection = searcher.Get();
foreach (ManagementObject m in queryCollection)
{
Console.WriteLine("DeviceID : {0}", m["DeviceID"]);
Console.WriteLine("ElementName : {0}", m["ElementName"]);
}
It's sad that PowerShell in Windows 2016 runs so slowly...
In fact, through WMI there are so many options how to get this data.
