I am trying to write a script which takes a text file of f5 LTM results and puts this into a searchable array so i can compare results from yesterday to today.
This is an example of the file;
MemberCount : 2
Name : /Common/blah1
Availability : AVAILABILITY_STATUS_GREEN
Enabled : ENABLED_STATUS_ENABLED
Status : The pool is available
MemberCount : 2
Name : /Common/blah2
Availability : AVAILABILITY_STATUS_GREEN
Enabled : ENABLED_STATUS_ENABLED
Status : The pool is available
So ideally I would like to make Name the unique field and the sort the list so i can compare the changes in status from yesterday to today.
Here is the code I am working on to email the results but it only provides line by line difference where I would rather get the object changes in the email.
Add-PSSnapIn iControlSnapIn
$f5_hosts = '192.168.x.x', '192.168.x.x'
$uid = 'xx'
$pwd ='xx'
foreach($f5_host in $f5_hosts){
$f5_host_out = $(get-date -f yyyyMMdd)+"_"+$f5_host+".txt"
$f5_host_out_yesterday = $((get-date).AddDays(-1).ToString('yyyyMMdd'))+"_"+$f5_host+".txt"
#Check login details and generate LTM output file for $f5_host
Initialize-F5.iControl -HostName $f5_host -Username $uid -password $pwd
Get-F5.LTMPool | out-file $f5_host_out
#// Check if EMP file for yesterday exists and send results else send error
if (Test-Path $f5_host_out_yesterday){
$f5_host_Result = compare-object -ReferenceObject (Get-Content $f5_host_out) -DifferenceObject (Get-Content $f5_host_out_yesterday )
$f5_host_out_yesterday+": file is Present!"
$Text_Body = $f5_host+": difference `r`n"
$Text_Body += ($f5_host_Result | out-string)
Send-MailMessage -to simon.thomason#racq.com.au -from simon.thomason#racq.com.au -subject $f5_host+": F5 Daily LTM Check" -body $Text_Body -smtpserver mailrelay.racqgroup.local
}else{
$f5_host_out_yesterday+": is not file is Present!"
Send-MailMessage -to simon.thomason#racq.com.au -from simon.thomason#racq.com.au -subject $f5_host+": Check failed" -body "Yesterday's file is not present" -smtpserver mailrelay.racqgroup.local
}
}
#Limit File retention to 30days.
$limit = (Get-Date).AddDays(-30)
#Get script location
$path = Get-Location
# Delete files older than the $limit.
Get-ChildItem -Path $path -Recurse -Force | Where-Object { !$_.PSIsContainer -and $_.CreationTime -lt $limit } | Remove-Item -Force
So as an output I would just want to see something like this in a email
Difference From yesterday to today
Yesterday
MemberCount : 2
Name : /Common/blah1
Availability : AVAILABILITY_STATUS_GREEN
Enabled : ENABLED_STATUS_ENABLED
Status : The pool is available
Today
MemberCount : 2
Name : /Common/blah1
Availability : AVAILABILITY_STATUS_RED
Enabled : ENABLED_STATUS_ENABLED
Status : The pool is available
Ok, on your second question, exporting and importing passwords, the encryption is done per user (and I'm pretty sure per machine), so you can't export it, and then have another account import it, but for just straight saving an encrypted password you can use these functions:
Function Out-EncryptedPasswordFile{
[cmdletbinding()]
Param(
[Parameter(Mandatory = $true)]
[string]$Password,
[Parameter(Mandatory = $true)]
[ValidateScript({If(Test-Path (Split-Path $_)){$true}else{Throw "Unable to create file, directory '$(Split-Path $_)\' does not exist."} })][String]$Path
)
ConvertTo-SecureString -AsPlainText $Password -Force | ConvertFrom-SecureString | Set-Content $Path -Encoding Unicode
}
#Usage Example
#Out-EncryptedPasswordFile TestP#ssw0rd c:\temp\password.txt
Function Import-EncryptedPasswordFile{
[cmdletbinding()]
Param(
[Parameter(Mandatory = $true)]
[ValidateScript({Test-Path $_})][string]$Path
)
$SSPassword = Get-Content $Path | ConvertTo-SecureString
$Ptr = [System.Runtime.InteropServices.Marshal]::SecureStringToCoTaskMemUnicode($SSPassword)
[System.Runtime.InteropServices.Marshal]::PtrToStringUni($Ptr)
[System.Runtime.InteropServices.Marshal]::ZeroFreeCoTaskMemUnicode($Ptr)
}
#Usage Example
#Import-EncryptedPasswordFile C:\temp\password.txt
not certain if right or wrong but this gave the result I was looking for. json was just used so I could store the object and convert it back to powershell object.
Add-PSSnapIn iControlSnapIn
$f5_hosts = 'x.x.x.x', 'x.x.x.x'
$uid = 'xx'
$pwd ='xx'
foreach($f5_host in $f5_hosts){
$f5_host_out = $(get-date -f yyyyMMdd)+"_"+$f5_host+".json"
$f5_host_out_yesterday = $((get-date).AddDays(-1).ToString('yyyyMMdd'))+"_"+$f5_host+".json"
#Check login details and generate LTM output file for $f5_host
Initialize-F5.iControl -HostName $f5_host -Username $uid -password $pwd
Get-F5.LTMPool | ConvertTo-Json | out-file $f5_host_out
#// Check if EMP file for yesterday exists and send results else send error
if (Test-Path $f5_host_out_yesterday){
$f5_host_json_today = Get-Content -Raw $f5_host_out | ConvertFrom-Json
$f5_host_json_yesterday = Get-Content -Raw $f5_host_out_yesterday | ConvertFrom-Json
$f5_host_Result = Compare-Object -ReferenceObject ($f5_host_json_today | Sort-Object ) -DifferenceObject ($f5_host_json_yesterday | Sort-Object ) -property MemberCount, Name, Status, Availability, Enabled, Status | sort-object -property Name

}
}
#Limit File retention to 30days.
$limit = (Get-Date).AddDays(-30)
#Get script location
$path = Get-Location
# Delete files older than the $limit.

I am trying to output SQL results to a .csv file using Powershell separated by its respective column.
The script I wrote works, but it will duplicate the same result three times in the csv. Even if I have only 1 result from the Select statement from the table, it will output it three times in the .csv file.
I tried using pscustomobject as well. But it throws me an error and does not output anything.

Is there a faster way to get a specific registry value from a list of servers? I'm selecting a text file of computers with different flavors of windows and getting the OS product name. I'm finding that it's taking a couple seconds per computer to retrieve.
Current script:
Clear-Host
# Prompt for file containing list of target
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$myDialog = New-Object System.Windows.Forms.OpenFileDialog
$myDialog.Title = "Select File of Target Systems"
$myDialog.InitialDirectory = $PSScriptRoot
$myDialog.Filter = "TXT (*.txt) | *.txt"
$result = $myDialog.ShowDialog()
If ($result -eq "OK") {
$Computers = Get-Content $myDialog.FileName
}
Else {
Write-Host "`nCancelled by User`n"
}
$Array = #()
# Loop Through Computers
ForEach ($Computer in $Computers) {
Write-Warning "Processing $Computer"
# Get Registry Values
Try {
$OSVersion = Invoke-Command -ComputerName $Computer -ScriptBlock { (Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name ProductName).ProductName }
# Create a custom object
$ComplexObject = New-Object PSCustomObject
$ComplexObject | Add-Member -MemberType NoteProperty -Name "Server name" -Value $Computer
$ComplexObject | Add-Member -MemberType NoteProperty -Name "OS Version" -Value $OSVersion
# Add custom object to our array
$Array += $ComplexObject
}
Catch {
$_.Exception.Message
Break
}
}
# Results
If ($Array) {
# Display results in new window
$Array | Out-GridView -Title "OS Version Results"
# Display results in PS console
$Array
}
My end goal later on in the script is to do different things based on the OS version so I want to separate them into independent lists:
If (We have Win2008 servers) {
"Do This"
}
If (We have Win2012R2 servers) {
"Do This"
}
Clear-Host
# Prompt for file containing list of target
[void] [System.Reflection.Assembly]::LoadWithPartialName("System.Windows.Forms")
$myDialog = [System.Windows.Forms.OpenFileDialog]::new()
$myDialog.Title = "Select File of Target Systems"
$myDialog.InitialDirectory = $PSScriptRoot
$myDialog.Filter = "TXT (*.txt) | *.txt"
$result = $myDialog.ShowDialog()
If ($result -eq "OK") {
$Computers = Get-Content $myDialog.FileName
}
Else {
Write-Host "`nCancelled by User`n"
}
# Get Registry Values
$Array = Try {
Invoke-Command -ComputerName $Computers -ScriptBlock {
(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" -Name ProductName).ProductName
} -ErrorAction stop | Select-Object #{n="Server Name";e={$_.pscomputername}},
#{n="OS Version";e={$_}}
}
Catch {
write-warning $_.Exception.Message
break
}
# Results
If ($Array) {
# Display results in new window
$Array | Out-GridView -Title "OS Version Results"
# Display results in PS console
$Array
}
You can use Get-AdComputer like:
Get-ADComputer -Filter {(OperatingSystem -like "*windows*server*") -and (Enabled -eq "True")} -Properties OperatingSystem | Select -ExpandProperty OperatingSystem | ForEach {
If($_ -match "Windows Server 2008.*"){
# Server 2008
}
If($_ -match "Windows Server 2012.*"){
# Server 2012
}
# Add more like 2016,2019
}
I'm working on a powershell script to read file attributes filtered by CreationTime on multiple shares. The scripts works, sporadically. It works great when I use a single path but I get mixed results when I add the folders paths to an array. The most disturbing result is when it successfully find and reads all path and then includes everything under c:windows\system32. Same anomaly when shares are empty.
So what I want to accomplish is:
Read list of Shares
Read each share content filtered by 'CreationTime' and 'Archive' attributes.
Save results to a csv file.
If file not empty, write results to event log.
here is the code
$timer = (Get-Date -Format yyy-MM-dd-HHmm)
$Date=(Get-Date).AddHours(-3)
$FolderList = "C:\Software\Scripts\FolderList.txt"
$Folders = get-content $FolderList
$Filepath = "C:\Software\Scripts"
$filename = "$Filepath\" + $timer + "OldFiles.csv"
foreach ($Folder in $Folders)
{
Get-ChildItem $Folder | Where-Object { $_.CreationTime -lt $Date -and $_.Attributes -band [System.IO.FileAttributes]::Archive} | Select Attributes, CreationTime, Fullname | Export-Csv -Path $filename -NoTypeInformation
}
if ( (get-childitem $filename).length -eq 0 )
{
exit
}
else{
#Write to OpsMgr Log
$Message = get-content $filename
Write-EventLog -LogName "Operations Manager" -Source "Health Service Script" -EventID 402 -EntryType Information -Message "Old files found. $Message"
}
This (untested) script might do what you want:
$Date = (Get-Date).AddHours(-3)
$FolderList = "C:\Software\Scripts\FolderList.txt"
$Folders = Get-Content $FolderList
$Filepath = "C:\Software\Scripts"
$timer = (Get-Date -Format yyyy-MM-dd-HHmm)
$filename = Join-Path $Filepath ("{0}_OldFiles.csv" -f $timer)
$Data = foreach ($Folder in $Folders){
Get-ChildItem $Folder |
Where-Object { $_.CreationTime -lt $Date -and
$_.Attributes -band [System.IO.FileAttributes]::Archive} |
Select Attributes, CreationTime, Fullname
}
if ($Data.Count){
#Write to OpsMgr Log
$Data | Export-Csv -Path $filename -NoTypeInformation
$Message = $Data | ConvertTo-Csv
Write-EventLog -LogName "Operations Manager" -Source "Health Service Script" `
-EventID 402 -EntryType Information `
-Message "Old files found. $Message"
}
I have a large list of hostnames I need to ping to see if they are up or down. I'm not really that great at scripting but I managed to figure this much out:
$names = Get-content "hnames.txt"
foreach ($name in $names){
if (Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue){
Write-Host "$name is up" -ForegroundColor Green
}
else{
Write-Host "$name is down" -ForegroundColor Red
}
}
This gets me what I need but i now need to write out these results to a csv file and i have no idea how to do that.
Please Help!
You can use the following code instead (I simply altered the write-host calls to CSV formatting) and execute it with "PowerShell.exe script.ps > output.csv"
Note that you must execute it from the folder that contains hnames.txt, or simply change the "hnames.txt" to a full path.
$names = Get-content "hnames.txt"
foreach ($name in $names){
if (Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue){
Write-Host "$name,up"
}
else{
Write-Host "$name,down"
}
}
P.S. You can also use the Out-File Cmdlet to create the CSV file
I am a complete newbie to Powershell, so I took this on as a learning task, as I needed a quick and simple way to check a list of PC's for up/down status. These tweaks were needed to get it to output cleanly to the screen and to a txt file
$Output= #()
$names = Get-content "hnames.txt"
foreach ($name in $names){
if (Test-Connection -ComputerName $name -Count 1 -ErrorAction SilentlyContinue){
$Output+= "$name,up"
Write-Host "$Name,up"
}
else{
$Output+= "$name,down"
Write-Host "$Name,down"
}
}
$Output | Out-file "C:\support\result.csv"
$Output= #()
$names = Get-Content ".\input\Servers.txt"
foreach ($name in $names){
if (Test-Connection -Delay 15 -ComputerName $name -Count 1 -ErrorAction SilentlyContinue -quiet){
$Output+= "$name,up"
Write-Host "$Name,up" -ForegroundColor Green
}
else{
$Output+= "$name,down"
Write-Host "$Name,down" -ForegroundColor Red
}
}
$Output | Out-file ".\output\result.csv"
This is a tad cleaner, and includes the original foreground options but, BTW, the 'delay' switch seems to be ignored -PB
I would do it this way. Using a list of computers and -asjob works very well. The Responsetime property (confusingly the header is "Time(ms)") will be non-null if the host is up.
$names = Get-content hnames.txt
test-connection $names -asjob -count 1 | receive-job -wait -auto
Source Destination IPV4Address IPV6Address Bytes Time(ms)

Lately I do it this way. It requires threadjobs installed in powershell 5.1. Or just use get-port. I stick it in a mymod\mymod.psm1 module file somewhere in $env:psmodulepath. I can check a classroom in under 10 seconds.
function get-pport { # multi-threaded
param($list)
$list |
% { $_ | start-threadjob { get-port $input } -throttlelimit 20 } |
receive-job -wait -auto
}
function Get-Port {
Param (
[parameter(ValueFromPipeline)]
[string[]]$Hostname='yahoo.com'
)
begin {
$ports = 22,5988,3389,5985
$ping = New-Object System.Net.Networkinformation.ping
$Timeout = 200 # ms
}
process {
$hostname | foreach {
$openPorts = #()
foreach ($port in $ports) {
$client = New-Object System.Net.Sockets.TcpClient
$beginConnect = $client.BeginConnect($_,$port,$null,$null)
Start-Sleep -Milli $TimeOut
if($client.Connected) { $openPorts += $port }
$client.Close()
}
$result = $Ping.Send($_, $timeout)
if (! $result) { write-error "hostname $_ not found" }
$pingstatus = ($result.status -eq 'Success')
New-Object -typename PSObject -Property #{
HostName = $_
Port = $openPorts
Ping = $pingstatus
} | select hostname,port,ping
} # end foreach
} # end process
}

$avid = cat afile.txt
pport $avid

The script searches all folders and subfolders and delete the oldest file when the number of files is>5. Everything works fine, but I want also log all the delete Files as a record in a log-file.
How can I log the deleted files ?
Here the Script.
$path = "C:\test\1"
$keep = 3
$strLogFileName = "c:\test\yourlogfile.log";
$dirs = Get-ChildItem -Path $path -Recurse | Where-Object {$_.PsIsContainer}
foreach ($dir in $dirs) {
$files = Get-ChildItem -Path $dir.FullName | Where-Object {-not $_.PsIsContainer -and $_.name -like "*.zip"}
if ($files.Count -gt $keep) {
$files | Sort-Object CreationTime -desc| Select-Object -First ($files.Count - $keep) | Remove-Item -Force
***{write-host “Deleting File $File” -foregroundcolor “Red”; Remove-Item $File | out-null}***
}
}
First you will need a log-message type function in your script that will log the message to a .log file. Then chekc if the file exists and if not then create a file.
Then just before you delete your file with Remove-Item command you can use Log-Message function to log message to the log file.
% { (Log-Message "Deleting File $_"); $_ }
Complete script
$path = "C:\test\1"
$keep = 3
$strLogFileName = "c:\test\yourlogfile.log";
function Log-Message
{
Param ([string]$logtext)
Add-content $strLogFileName -value $logtext
}
$dirs = Get-ChildItem -Path $path -Recurse | Where-Object {$_.PsIsContainer}
foreach ($dir in $dirs) {
$files = Get-ChildItem -Path $dir.FullName | Where-Object {-not $_.PsIsContainer -and $_.name -like "*.zip"}
if ($files.Count -gt $keep) {
$files | Sort-Object CreationTime -desc| Select-Object -First ($files.Count - $keep) |
% { $dt=get-date;(Log-Message "Deleting File $_ on $dt");$_ }| Remove-Item -Force
}
}
You've got a good start here:
write-host “Deleting File $File” -foregroundcolor “Red”
Unfortunately Remove-Item doesn't have any output that you can mooch from, but you've already made your own output message so we can just build from that. You can pipe any output to a file by using Out-File. The append flag will attach the new content to the end of the file, and you do not have to check if the file exists.
Write-Output “Deleting File $File” | Out-File -Append logfile.txt
You don't even have to include Write-Output, if you want a shorter line.
Here is an example that shows where you need to add code. I've marked existing code with "...", and I've moved the deletion message into a variable so that you can reuse it at another location. This assumes that you've stored the selected filename in a variable.
...
if ($files.Count -gt $keep)
{
...
$message = "Deleting File $File at "+(Get-Date)
$message | Out-File -Append logfile.txt
}
...
