Query Multiple event id using Get-EventLog - powershell

I have a list of event id which I need to query on Multiple Server using PowerShell 2.0. Below is the script:
$a = Get-Date
$b = $a.AddDays(-1)
$b = $b.ToShortDateString();
$StartTime = "10:00:00 PM"
$EndTime = "11:00:00 PM"
$SMS_000 = "XXSMS01"
$SMS_SQL_000 = "XXXXXSQL01"
Get-EventLog -ComputerName $SMS_000, $SMS_SQL_000 -LogName Application -After $b -Before $b -Source "SMS Server" | ?{$_.EventID -eq 5055 -and $_.Event -eq 6829}
I would like to store the result into an obj which I shall then be passing to creation of an HTML report. The above is just a part of the process. Thanks!

$events = Get-EventLog -ComputerName $SMS_000, ...
However, you need to change your filter from
?{$_.EventID -eq 5055 -and $_.Event -eq 6829}
to
?{$_.EventID -eq 5055 -or $_.EventID -eq 6829}
because $_.Event isn't a valid property and one event can't have 2 different IDs.

Problem with powershell script for AD server Status

I have a script that can have a list of AD servers (with Get-ADComputer) and the results goes to a TXT file. I don't know how to only have Online Servers only. I only need their names.
I tried to do some IF {} Else{} with the cmdlet Test-Connection -CN $Server but it doesn't work (I'm probably doing it wrong). Here is my code :
$TXTFile = "C:\Scripts\Serv.txt"
$TXTOutput = #()
Write-Host "INFO: Finding servers from AD"
$Servers = Get-ADComputer -Filter {OperatingSystem -like "*server*" -and Enabled -eq $true} | SORT Name
Write-Host "INFO:"$Servers.Count"Records found"
ForEach ($Server in $Servers) {
$ServerHash = $NULL
$ServerHash = [ordered]#{
"Servers Name" = $Server.Name
}
$TXTOutput += New-Object PSObject -Property $ServerHash
}
$TXTOutput
I want, if possible, to have all of my AD Online Servers name in a TXT file. For now I only have all of my servers (Online and Offline). It's my first post so sorry if I made it wrong !
You can use -Quiet parameter with Test-Connection cmdlet in order to get just True or False and then make a decision based on that result.
$TXTFile = "C:\Temp\Serv.txt"
$TXTOutput = #()
$servers=Get-ADComputer -Filter {OperatingSystem -like "*server*" -and Enabled -eq $true} | select -expandproperty Name
ForEach ($Server in $Servers) {
if ((Test-Connection $Server -Count 2 -Quiet) -eq $true) {
$TXTOutput += $Server
}
}
$TXTOutput | Out-File $TXTFile
You can pipe $TXTOutput to sort if you want. Keep in mind that this might take a while since you are basically pinging each server twice -Count 2.

Get-EventLog with Append

So i have this code below that collects the stated EventIDs with the use of append. The problem is have is it only saves to a single file. What i want to do is save the collection to a daily file so i can do a daily report. A little help please?
$endtime = Get-Date
$starttime = (Get-Date).AddHours(-3)
$domain = "ComputerName"
$event = get-eventlog security -ComputerName $domain -after $starttime -before $endtime | where-object {($_.EventID -eq 4724) -or ($_.EventID -eq 4723) -or ($_.EventID -eq 4720)}
$event | select MachineName,EventID,TimeGenerated,Message | export-csv -path "E:\EventLogs\temp.csv"
get-content "E:\EventLogs\temp.csv" | out-File -filepath "E:\EventLogs\AccountAudit.csv" -append -enc ASCII -width 500
Export-Csv Has an -Append Parameter as well, you can shorten your code to:
$event = get-eventlog security -ComputerName $domain -after $starttime -before $endtime |
Where-object {($_.EventID -eq 4724) -or ($_.EventID -eq 4723) -or ($_.EventID -eq 4720)}
$event | select MachineName,EventID,TimeGenerated,Message |
Export-Csv -path "E:\EventLogs\AccountAudit.csv" -Append -Encoding ASCII
Simply add a get-start with some parameters to get a date that's filename friendly (no "/" for example) and save it in a variable. Then replace AccountAudit on the last line with the variable.

powershell restart service if failed

i have the Problem that an Service is crashing whitout stopping.
This means the status is shown as running but...
However - i wrote a small (absolute Beginner(!)-)Powershell-Script to check if the app is crashed, but how do i have to continue?
If the Script finds an entry in the Eventlog it shoud stop and start the Service..
Clear-Host
$timetocheck = [DateTime]::Now.AddMinutes(-10)
$eventid = "10016"
$log = "System"
$app = "SID"
$check = "Get-WinEvent -LogName $log | Where-Object {($_.TimeCreated -ge $timetocheck) -and ($_.id -eq $eventid) -and ($_.Message -Like *$app*)}"
edit
just to clarify -
if this snippet finds nothing in the eventlog nothing should happen.
if this snippet finds at least 1 error in the eventlog the service should be stopped and restarted.
with other words - if process crashed restart else do nothing
thx
Well - now i can answer my own question.. ;)
This works:
Clear-Host
$timetocheck = [DateTime]::Now.AddMinutes(-30)
$eventid = "10016"
$log = "System"
$app = "SID"
$checking = Get-WinEvent -FilterHashtable #{Logname="$log";ID="$eventid" ;StartTime="$timetocheck"}|`
Where-Object {$_.Message -like "*$app*"}
if ($checking -like "*") {ReStart-Service -Name DistributedCOM -Force}
The Trick is the $checking -like "*". I´m not satisfied completely because this "only" checks if the Get-Winevent replys at least one sign. I would prefer to search for a string i know....
When the string to check is shorter its working with a defined string....
However - its working. And thats important. And maybe someone else needs this to.
thx to all
edit
and the first improvment....
the command Get-WinEvent -FilterHashtable #{Logname="$log";ID="$eventid" ;StartTime="$timetocheck"}| Where-Object {$_.Message -like "$app"}
takes 0,7 seconds
the command Get-WinEvent $log | Where-Object{($.TimeCreated -ge $timetocheck) -and ($.id -eq $eventid) -and ($_.Message -Like "$app")} takes 4,2 seconds
so i changed it
Try it with the following code
Clear-Host
$timetocheck = [DateTime]::Now.AddMinutes(-10)
$eventid = "10016"
$log = "System"
$app = "SID"
$check = Get-WinEvent -LogName $log | Where-Object {($_.TimeCreated -ge $timetocheck) -and ($_.id -eq $eventid) -and ($_.Message -Like "*$app*")}
if ($check -ne $null)
{
Restart-Service -Name YourService -Force
}

Powershell List of Computers

How can I make this use a list of servers
Tried doing $ComputerList = gc <list location> but it doesnt seem to be working
correctly with one computer
$Start = (Get-Date).AddMinutes(-120)
$ComputerList = $env:ComputerName
$Events = gc C:\Temp\ErrorCodes.txt
# Getting all event logs
Get-EventLog -AsString -ComputerName $Computername |
ForEach-Object {
# write status info
Write-Progress -Activity "Checking Eventlogs on \\$ComputerName" -Status $_
# get event entries and add the name of the log this came from
Get-EventLog -LogName $_ -EntryType Error, Warning -After $Start -ComputerName $ComputerName -ErrorAction SilentlyContinue |
Add-Member NoteProperty EventLog $_ -PassThru | Where-Object {$Events -contains $_.eventid}
} |
# sort descending
Sort-Object -Property EventLog |
# select the properties for the report
Select-Object EventLog, EventID, TimeGenerated, EntryType, Source, Message
# output into grid view window
Out-GridView -Title "All Errors & Warnings from \\$Computername"
Force it to be an array.. Otherwise it will come in as a string if there is only one item
$ComputerList = #(gc c:\folder\computerlist.txt)
PowerShell: How can I to force to get a result as an Array instead of Object

Powershell Security Log Get-EventLog

I am trying to write something up in powershell and completely new to powershell, I need help. What I'm trying to do is get information from the Security Log. Specifically, the last login for users over the last two weeks. The code that I have so far is getting login's for the event ID 4624 based on the last 100 events. This is also returning not just users but computers as well. How can I limit the results to just users over a period of two weeks? Is this even possible?
$eventList = #()
Get-EventLog "Security" -After $Date `
| Where -FilterScript {$_.EventID -eq 4624 -and $_.ReplacementStrings[4].Length -gt 10} `
| foreach-Object {
$row = "" | Select UserName, LoginTime
$row.UserName = $_.ReplacementStrings[5]
$row.LoginTime = $_.TimeGenerated
$eventList += $row
}
$eventList
EDIT: Solved with code
$Date = [DateTime]::Now.AddDays(-14)
$Date.tostring("MM-dd-yyyy"), $env:Computername
$eventList = #()
Get-EventLog "Security" -After $Date `
| Where -FilterScript {$_.EventID -eq 4624 -and $_.ReplacementStrings[4].Length -gt 10 -and $_.ReplacementStrings[5] -notlike "*$"} `
| foreach-Object {
$row = "" | Select UserName, LoginTime
$row.UserName = $_.ReplacementStrings[5]
$row.LoginTime = $_.TimeGenerated
$eventList += $row
}
$eventList
Use -before and -after parameters to filter the log by date. Use get-help get-eventlog -full to see all the parameters.
The users's last logon is stored in Active Directory. Seems like it would be a lot easier to pull it from there than chewing through event logs.
Use PowerShell to search the Active Directory:
Import-Module ActiveDirectory
Get-QADComputer -ComputerRole DomainController | foreach {
(Get-QADUser -Service $_.Name -SamAccountName username).LastLogon.Value
} | Measure-Latest
