Documenting with PowerShell: Chapter 1 – Server overview page

In the previous blog I’ve showed how to upload data to IT-Glue by creating a new flexible asset with two fields: a name field on which we perform a match if a document exists, and a field where we placed some data. This time, we’re going to upload an entire HTML file we’ll create by gathering data from the server we run the script on. So, let’s get started

The scripts below can also be downloaded for your RMM system, find the AMP file here.

Data gathering

First, We’ll make a list of all the data that is imported for us to have documented. For me, that would be the following list of information:

  • Server Name
  • Server type (A physical or virtual machine)
  • How much RAM the machine currently has assigned
  • The NIC configuration
  • What applications are installed
  • What server roles are installed
  • What the physical disk layout is
  • What the RAID layout is

Let’s get started with each of the data collection parts. In the following script we check if the model contains “Virtual” or “VMWare”. two signs that show if a machine is a physical or virtual machine.

$ComputerSystemInfo = Get-CimInstance -ClassName Win32_ComputerSystem
if($ComputerSystemInfo.model -match "Virtual" -or $ComputerSystemInfo.model -match "VMware") { $MachineType = "Virtual"} Else { $MachineType = "Physical"}

To get the amount of RAM we run the following oneliner

1

$RAM = (systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

Applications and roles are also quite easy to get

$ApplicationsFrag = Get-ItemProperty HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName, DisplayVersion, Publisher, InstallDate | Convertto-html -Fragment | select -skip 1
$ApplicationsTable = "<br/><table class=`"table table-bordered table-hover`" >" + $ApplicationsFrag

$RolesFrag = Get-WindowsFeature | Where-Object {$_.Installed -eq $True} | Select-Object displayname,name  | convertto-html -Fragment | Select-Object -Skip 1
$RolesTable = "<br/><table class=`"table table-bordered table-hover`" >" + $RolesFrag

For the NIC configuration, we need to do a little more work. We want the NIC configuration to show both IPv4 and IPv6 configurations. We also want to look up all NIC configurations, if a server has multiple NICs.

$networkName = Get-CimInstance -ClassName Win32_NetworkAdapter | Where-Object {$_.PhysicalAdapter -eq "True"} | Sort Index
$networkIP = Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration | Where-Object {$_.MACAddress -gt 0} | Sort Index
$networkSummary = New-Object -TypeName 'System.Collections.ArrayList'

foreach($nic in $networkName) {
    $nic_conf = $networkIP | Where-Object {$_.Index -eq $nic.Index}

    $networkDetails = New-Object PSObject -Property @{
        Index                = [int]$nic.Index;
        AdapterName         = [string]$nic.NetConnectionID;
        Manufacturer         = [string]$nic.Manufacturer;
        Description          = [string]$nic.Description;
        MACAddress           = [string]$nic.MACAddress;
        IPEnabled            = [bool]$nic_conf.IPEnabled;
        IPAddress            = [string]$nic_conf.IPAddress;
        IPSubnet             = [string]$nic_conf.IPSubnet;
        DefaultGateway       = [string]$nic_conf.DefaultIPGateway;
        DHCPEnabled          = [string]$nic_conf.DHCPEnabled;
        DHCPServer           = [string]$nic_conf.DHCPServer;
        DNSServerSearchOrder = [string]$nic_conf.DNSServerSearchOrder;
    }
    $networkSummary += $networkDetails
}
$NicRawConf = $networkSummary | select AdapterName,IPaddress,IPSubnet,DefaultGateway,DNSServerSearchOrder,MACAddress | Convertto-html -Fragment | select -Skip 1
$NicConf = "<br/><table class=`"table table-bordered table-hover`" >" + $NicRawConf

If a server is a physical machine, and a Dell server I also want to see the disk configuration. For this, you’ll need OpenManage installed.

if($machineType -eq "Physical" -and $ComputerSystemInfo.Manufacturer -matchf "Dell"){
$DiskLayoutRaw = omreport storage pdisk controller=0 -fmt cdv
$DiskLayoutSemi = $DiskLayoutRaw |  select-string -SimpleMatch "ID,Status," -context 0,($DiskLayoutRaw).Length | convertfrom-csv -Delimiter "," | select Name,Status,Capacity,State,"Bus Protocol","Product ID","Serial No.","Part Number",Media | convertto-html -Fragment
$DiskLayoutTable = "<br/><table class=`"table table-bordered table-hover`" >" + $DiskLayoutsemi

#Try to get RAID layout
$RAIDLayoutRaw = omreport storage vdisk controller=0 -fmt cdv
$RAIDLayoutSemi = $RAIDLayoutRaw |  select-string -SimpleMatch "ID,Status," -context 0,($RAIDLayoutRaw).Length | convertfrom-csv -Delimiter "," | select Name,Status,State,Layout,"Device Name","Read Policy","Write Policy",Media |  convertto-html -Fragment
$RAIDLayoutTable = "<br/><table class=`"table table-bordered table-hover`" >" + $RAIDLayoutsemi
}else {
    $RAIDLayoutTable = "Could not get physical disk info"
    $DiskLayoutTable = "Could not get physical disk info"
}

Putting all of that together will give us the following script, I’ve also added some headers to make the output HTML file look nice. You can use this as a stand-alone script.

To upload this data to IT-Glue, we can use the exact same script as we’ve used last time, with two small edits; the title of the flexible asset, and the description.

And that’s it! Happy PowerShelling! the next chapter will be how to upload the Bitlocker key for a client machine to IT-Glue as a password object, it will also tag all related devices, something that’s pretty cool!
