Task Manager thread counts and username query - powershell

I'm new to working with powershell and I'm trying to create a script where I can check a remote machines specific process thread counts along with the username and in the output I hope I can get the highest thread user.
I'm started from this script as a reference but I can't seen to find the right commands/syntax
Get-Process | Select-Object Name, #{Name='ThreadCount';Expression ={$_.Threads.Count}} | Sort-Object -Property Threadcount -Descending

Get-Process have an optional -IncludeUserName switch argument you can include to get the username out of the command. It will requires admin. priviledge to collect that information.
Once you have the information, you will need to group by user and then sort by the sum of threads per user to get your desired "Highest thread users".
Here is what that would look like.
#requires -runasadministrator
$ProcessesSummary = Get-Process -IncludeUserName |
Select-Object Name, #{Name = 'ThreadCount'; Expression = { $_.Threads.Count } },Username
$ProcessesSummary |
Group-Object -Property Username |
Select Name,#{N='TotalThreads';E={($_.Group.ThreadCount |
Note that if you do not do anaything with $ProcessesSummary other than using it for the total thread per user, you can forego the first statement completely and instead just do
#requires -runasadministrator
Get-Process -IncludeUserName |
Group-Object -Property Username |
Select Name,#{N='TotalThreads';E={($_.Group.Threads.Count | Measure-Object -Sum).Sum}} |
Sort TotalThreads -Descending |
Where Name -NotLike 'NT*' # If you want to remove some of the system accounts from the output

Sorting Office 365 user account / mailbox properties

I'm accessing my cloud Office 365 Exchange Server via Powershell. Showing all properties of an account can be done via Get-Mailbox 'username' | Select * (MS reference).
On most systems those properties are already sorted (e.g. Get-ADUser 'username' -Properties *). Is it possible to sort the Get-Mailbox output? I thought Get-Mailbox 'username' | Select * | Sort-Object would do the trick but it didn't make any difference (I guess a property doesn't constitute an object). What's the right command to sort the properties for a single user?
Note: Sorting properties of multiple accounts works fine e.g. Get-Mailbox -filter * | select Name, DisplayName | Sort-Object Displayname
Update:
I managed to get a sorted properties list using
(Get-Mailbox 'mailboxname' | select *).PSObject.properties | ForEach-Object {$_.Name} | Sort-Object Name
it gets me the following output:
AcceptMessagesOnlyFrom
AccountDisabled
AddressBookPolicy
ArchiveWarningQuota
...
$_.Name gives me the values but so far I couldn't combine both into one list, I'm trying to get s.th. like this:
AcceptMessagesOnlyFrom = {}
AccountDisabled = False
AddressBookPolicy =
ArchiveWarningQuota = 45 GB (48,318,382,080 bytes)
...
I'm not completely sure this is what you are after, let me know if I'm wrong. As in my comment, Sort-Object can handle sorting a list or an object[] by one or more of it's properties; but sorting one single object by it's properties, say alphabetically, would require a combination of accessing the object's properties with .PSObject.Properties.Name and then sorting this list with Sort-Object. And after that we can use Select-Object with this sorted list to display the object as we want.
Using the object below as an example as I have no idea how of the type Microsoft.Exchange.Data.Directory.Management.Mailbox looks.
$mailbox = [pscustomobject]#{
DisplayName = 'someuser'
UserPrincipalName = 'someuser#somedomain.com'
Mail = 'someuser#somedomain.com'
IsLicensed = $true
}
$properties = $mailbox.PSObject.Properties.Name | Sort-Object
$mailbox | Select-Object $properties
As you can see, object's properties are now sorted alphabetically:
DisplayName IsLicensed Mail UserPrincipalName
----------- ---------- ---- -----------------
someuser True someuser#somedomain.com someuser#somedomain.com
By looking at your edit, seems like you are looking for a one-liner, so this is how it could look:
Get-Mailbox 'mailboxname' | ForEach-Object {
$_ | Select-Object ($_.PSObject.Properties.Name | Sort-Object)
}

How can I use powershell to group process names and show the sum of memory used

I am trying to wrap my head around combining powershell options in order to produce a simple table of the top 10 memory users on my system (server, pc, etc). My PC is Windows 7 with no timeline in site for upgrade to Windows 10 due to Covid 19. I cannot add applications to my work PC that has not gone through a vetting process (read, it takes forever) so most of the time I create my own.
I would like to produce a result that looks something like this:
Count Name Memory Sum in MB
10 Firefox 5000
3 javaw 1000
The order I would like to be able to select by changing a property in the powershell options. So for example, sort by count, name or memory. My sample table is not set in stone.
I have come across the following 2 pieces of powershell and have been trying to adapt them but get errors.
(Get-Process | Measure-Object WorkingSet -sum).sum /1gb
Get-Process | Group-Object -Property Name -NoElement | Where-Object {$_.Count -gt 1}
For sake of learning, I don't mind seeing an "ugly" version and an optimized version.
You can use this:
$proc=ps|select -eXp name;$proc2=#()
$proc|%{
if(!("$($_)" -in $proc2)){$proc2+="$($_)"
$mem=0;ps $_|select -eXp workingSet|%{$mem+=$_/1MB}
[pscustomobject][ordered]#{
'Count'=(ps $_ -ea silentlyContinue).Count
'Name'=$_
'Memory in MB'=$mem
}}}
The PSCustomObject accelerator was introduced in PowerShell v3 so I don't know if the the output looks like a table in Windows 7 however the following pipeline returns desired properties even in PowerShell v2:
Get-Process |
Group-Object -Property Name -NoElement |
Where-Object { $_.Count -gt 1 } |
ForEach-Object {
[PSCustomObject]#{
Count= $_.Count
Name = $_.Name
'Memory Sum in MB' = [math]::Round(( Get-Process -Name $_.Name |
Measure-Object WorkingSet -sum).sum /1Mb, 3)
}
} # | Sort-Object -Property 'Memory Sum in MB'

PowerShell property expression increases execution time by 4-5 times

Scroll down for TL;DR
I need to get the following properties for every process as quickly as possible, ideally 5 seconds, maximum 10 seconds: ID, Name, Description, Path, Company, Username, Session ID, StartTime, Memory, CPU (percentage, not time)
To get this data, I put together the following snippet which (I think) is functionally perfect:
$ProcessCPU = Get-WmiObject Win32_PerfFormattedData_PerfProc_Process | Select-Object IDProcess, PercentProcessorTime
$Processes = Get-Process -IncludeUserName |
Select-Object `
#{Name='Id';Expression={[int]$_.Id}},
#{Name='Name';Expression={[string]$_.Name}},
#{Name='Description';Expression={[string]$_.Description}},
#{Name='Path';Expression={[string]$_.Path}},
#{Name='Company';Expression={[string]$_.Company}},
#{Name='Username';Expression={[string]$_.UserName}},
#{Name='SessionId';Expression={[string]$_.SessionId}},
#{Name='StartTime';Expression={[string](($_.StartTime).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"))}},
#{Name='MemoryMB';Expression={[int]([math]::Round($_.WorkingSet/1MB,2))}},
#{Name='CPUPercent';Expression={
[int]($ProcessCPU | ?{'IDProcess' -eq $_.Id}).PercentProcessorTime
}}
The issue is that its taking 18-22 seconds to execute, caused by this line (which adds about 16 seconds):
#{Name='CPUPercent';Expression={
[int]($ProcessCPU | ?{'IDProcess' -eq $_.Id}).PercentProcessorTime
}}
PS C:\Windows\system32> Measure-Command -Expression {
$ProcessCPU = Get-WmiObject Win32_PerfFormattedData_PerfProc_Process | Select-Object IDProcess, PercentProcessorTime
$Processes = Get-Process -IncludeUserName |
Select-Object `
#{Name='Id';Expression={[int]$_.Id}},
#{Name='Name';Expression={[string]$_.Name}},
#{Name='Description';Expression={[string]$_.Description}},
#{Name='Path';Expression={[string]$_.Path}},
#{Name='Company';Expression={[string]$_.Company}},
#{Name='Username';Expression={[string]$_.UserName}},
#{Name='SessionId';Expression={[string]$_.SessionId}},
#{Name='StartTime';Expression={[string](($_.StartTime).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"))}},
#{Name='MemoryMB';Expression={[int]([math]::Round($_.WorkingSet/1MB,2))}},
#{Name='CPUPercent';Expression={
[int]($ProcessCPU | ?{'IDProcess' -eq $_.Id}).PercentProcessorTime
}}
}
TotalSeconds : 19.061206
When I remove the slow property expression noted above and keep the WMI query, execution takes about 4.5 seconds:
Measure-Command -Expression {
$ProcessCPU = Get-WmiObject Win32_PerfFormattedData_PerfProc_Process | Select-Object IDProcess, PercentProcessorTime
$Processes = Get-Process -IncludeUserName |
Select-Object `
#{Name='Id';Expression={[int]$_.Id}},
#{Name='Name';Expression={[string]$_.Name}},
#{Name='Description';Expression={[string]$_.Description}},
#{Name='Path';Expression={[string]$_.Path}},
#{Name='Company';Expression={[string]$_.Company}},
#{Name='Username';Expression={[string]$_.UserName}},
#{Name='SessionId';Expression={[string]$_.SessionId}},
#{Name='StartTime';Expression={[string](($_.StartTime).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"))}},
#{Name='MemoryMB';Expression={[int]([math]::Round($_.WorkingSet/1MB,2))}}
}
TotalSeconds : 4.5202906
I thought that by getting all of the required data in a single query and referring back to the $ProcessCPU array would be fast - but I appreciate I'm iterating through each of the 250 arrays stored in $Processes.
TL;DR:
Is there a more performant method of joining two objects on a common property rather than using iteration as I have above? I.E. $ProcessCPU.IDProcess on $Processes.Id?
I tried the following block to test $Output = $ProcessCPU + $Processes | Group-Object -Property Id, it executed in just 3 seconds, but the output wasn't acceptable:
PS C:\Windows\system32> Measure-Command -Expression {
$ProcessCPU = Get-WmiObject Win32_PerfFormattedData_PerfProc_Process | Select-Object #{Name='Id';Expression={[int]$_.IDProcess}}, PercentProcessorTime
$Processes = Get-Process -IncludeUserName |
Select-Object `
#{Name='Id';Expression={[int]$_.Id}},
#{Name='Name';Expression={[string]$_.Name}},
#{Name='Description';Expression={[string]$_.Description}},
#{Name='Path';Expression={[string]$_.Path}},
#{Name='Company';Expression={[string]$_.Company}},
#{Name='Username';Expression={[string]$_.UserName}},
#{Name='SessionId';Expression={[string]$_.SessionId}},
#{Name='StartTime';Expression={[string](($_.StartTime).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"))}},
#{Name='MemoryMB';Expression={[int]([math]::Round($_.WorkingSet/1MB,2))}}
$Output = $ProcessCPU + $Processes | Group-Object -Property Id
}
TotalSeconds : 2.9656969
Use CIM to build up a hashtable that maps process IDs (PIDs) to their CPU percentages first.
Then make the calculated property passed to Select-Object consult that hashtable for efficient lookups:
Get-CimInstance Win32_PerfFormattedData_PerfProc_Process |
ForEach-Object -Begin { $htCpuPctg=#{} } `
-Process { $htCpuPctg[$_.IdProcess] = $_.PercentProcessorTime } #`
Get-Process -IncludeUserName |
Select-Object Id,
Name,
Description,
Path,
Company,
UserName,
SessionId,
#{Name='StartTime';Expression={[string](($_.StartTime).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssZ"))}},
#{Name='MemoryMB';Expression={[int]([math]::Round($_.WorkingSet/1MB,2))}},
#{Name='CPUPercent';Expression={ $htCpuPctg[[uint32] $_.Id] }}
Note:
Get-CimInstance rather than Get-WimObject is used, because the CIM cmdlets superseded the WMI cmdlets in PowerShell v3 (released in September 2012). Therefore, the WMI cmdlets should be avoided, not least because PowerShell Core, where all future effort will go, doesn't even have them anymore. For more information, see this answer.
There is usually no need to use calculated properties such as #{Name='Id';Expression={[int]$_.Id}} to simply extract a property as-is - just use the property's name - Id - as a Select-Object -Property argument (but you've since clarified that you're using calculated properties because you want explicit control over the property's data type for sending data to an IoT Gateway via JSON).
Note that CIM reports PIDs as [uint32]-typed values, whereas Get-Process uses [int] values - hence the need to cast to [uint32] in the hashtable lookup.

Using PoSH to get a value, strange results

I am using PoSH to query our Exchange server to return the largest mailbox by users.
My PoSH is:
$test = Get-MailboxDatabase MBX_* -Status | select Name,#{Name="NumberofUsers";Expression={(Get-Mailbox -resultsize unlimited -Database $_.name).Count}} | Sort -Property NumberofUsers | Select Name -First 1
This works in console and returns:
Name
----
MBX_2
However when I run it like this in a script and return the value, it is like this:
$test = Get-MailboxDatabase -Status MBX_*| select Name,#{Name="NumberofUsers";Expression={(Get-Mailbox -resultsize unlimited -Database $_.name).Count}} | Sort -Property NumberofUsers | Select Name -First 1
Write-Host "Using $test"
Using #<Name=MBX_2>
Why is it including the #<Name=> characters and how can I prevent it from doing that? I need to be able to grab just the returned value of "MBX_2" for the next part of my script and I am confused on how to go about this...
You are selecting a single property of the object, but still passing an object. What you need to do is use the -ExpandProperty parameter of the Select-Object cmdlet. Change your Select command to this:
| Select -ExpandProperty Name -First 1
That should give you the results that you desire.

how to get exact user name from get-mobiledevicestatistics in powershell

I have a small script to get all user mobile devices info from exchange 2013 server.
Get-Mailbox -ResultSize Unlimited |
ForEach {Get-MobileDeviceStatistics -Mailbox:$_.Identity} |
Select-Object #{label="User" ; expression={$_.Identity}},DeviceOS, lastsuccesssync
I just want to get an exact user name instead of a path in AD. How can I do it in expression={?}
Here is another script to do it, it gives me the user name, but all devices belongs to user are not in separated lines, they all in one line...
$EASMailboxes = Get-CASMailbox -Filter {HasActiveSyncDevicePartnership -eq $True -and DisplayName -notlike "CAS_{*"} | Get-Mailbox
$EASMailboxes | Select-Object DisplayName, PrimarySMTPAddress, #{Name="Mobile Devices";Expression={(Get-MobileDeviceStatistics -Mailbox $_.Identity).DeviceOS}} |
Out-GridView
I don't have the environment to test this but is this not what you are looking for ?
Get-Mailbox -ResultSize Unlimited | ForEach {
$user = $_.SamAccountName
Get-MobileDeviceStatistics -Mailbox:$_.Identity |
Select-Object #{label="User" ; expression={$user}},DeviceOS, lastsuccesssync
}
That should output the user for every device they own on its own line. You could then easily export this to Export-CSV or some such thing that way.
We save the $user so it is available later in the pipe. Could also have used Add-Member but the result would have been the same.
If you have the identity field, which looks like this
domain.com/Users/OU/UserName/ExchangeActiveSyncDevices/iPhone
Then to split on the / and get the third result, you simply request:
$_.Identity.Split("/")[3]
>UserName
PowerShell begins indexing with number zero, so to request the fourth entry in the list, we request index number 3.
Update
OP mentioned that the OU level might vary, meaning that he couldn't count on a fixed position to request the Index. In order to accomodte that scenario, try this method, which will look for the index of ExchangeActiveSyncDevices and then pick the index position before that.
$_.Identity.Split('/')[($_.Identity.Split('/').Indexof('ExchangeActiveSyncDevices')-1)]
Get-Mailbox -resultsize unlimited|foreach {Get-MobileDeviceStatistics -Mailbox:$_.identity} |Select-Object #{l="user";e={$_.Identity.parent.parent.name}}, lastsuccesssync
