PowerShell Scripting with Get-Eventlog

Introduction to Scripting Eventlog on a Remote Machine

Challenge, to interrogate logs on a remote machine.

PowerShell Eventlog Topics

Example 1: Eventlog -list
Window 8 Event Viewer Logs
Summary of Eventlog

PowerShell Pre-requisites and Checklist

In the case of Windows 7 and Server 2008, you don't need to download any extra files, just 'Add Feature' Windows PowerShell. However, for older operating systems, installing can be confusing because there are different versions of PowerShell for XP, Windows Server 2003 and Vista. For such legacy systems only, you need to download PowerShell from Microsoft's site.

Once you have installed PowerShell 2.0, I recommend choosing the ISE (Integrated Scripting Engine) version, it will save you buying a text editor.

Example 1: Eventlog with System.Diagnostics

Learning Points

Note 1: New-Object creates an instance of system.diagnostics. In particular an eventLog instance

Note 2: I have used variables to control the output, $Log, $Computer and $ID.

Important: Please amend $Computer = "LocalHost" to the name of the remote computer.

# PowerShell script to list the eventlogs on another computer
$Log = "Application"
$Computer ="LocalHost"
$ID = "1002"

$Objlog = New-Object system.diagnostics.eventLog($Log, $Computer)
$Objlog.get_entries() |
Where-object { $_.eventID -eq $id }

More work

Introduce an $array and a loop to interrogate a batch of computers.

Guy Recommends: The Free IP Address Tracker (IPAT)

Calculating IP Address ranges is a black art, which many network managers solve by creating custom Excel spreadsheets. IPAT cracks this problem of allocating IP addresses in networks in two ways:

For Mr Organized there is a nifty subnet calculator, just enter the network address and the subnet mask, then IPAT works out the usable addresses and their ranges. For Mr Lazy IPAT discovers, and then displays, the IP addresses of existing computers.
