Example 1: Eventlog with System.Diagnostics

Instructions:

Pre-requisite: Visit Microsoft's site and download the correct version of PowerShell for your operating system.

Here are instructions for executing the PowerShell code from the command line.

Launch Windows PowerShell
Copy all the lines of code into memory
(For instance, from the Example below)
Right-click on the PowerShell symbol
Edit --> Paste
Check the menus on screenshot to the right
Press 'Enter' to execute the pasted code

# 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 }

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.

More work

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

Guy Recommends: SolarWinds LANSurveyor

LANSurveyor will produce a neat diagram of your network topology. But that's just the start; LANSurveyor can create an inventory of the hardware and software of your machines and network devices. Other neat features include dynamic update for when you add new devices to your network. I also love the ability to export the diagrams to Microsoft Visio.

Finally, Guy bets that if you take a free trial of LANSurveyor then you will find a device on your network that you had forgotten about, or someone else installed without you realizing!
