Was tasked with monitoring Citrix Licenses. We needed a way to gauge when demand was the highest and overall utilization. Following is a PowerShell script that runs every 15 minutes and stores the result in a SQL Express DB. Will be using PowerGadgets at a later point to present a graphical representation of the data.
First the function to grab the Citrix info:
Function Get-CitrixLicenses {
$Licenses = Get-WmiObject `
-class 'Citrix_GT_License_Pool' `
-Namespace "ROOT\CitrixLicensing" `
-ComputerName $_ Select __Server, Count, InUseCount
$dt = Get-Date -Format g
foreach ($License in $Licenses) {
$obj = New-Object psObject
$obj Add-Member NoteProperty Server $License.__Server
$obj Add-Member NoteProperty Total $License.Count
$obj Add-Member NoteProperty InUse $License.InUseCount
$obj Add-Member NoteProperty Date $dt
Write-Output $obj }
}
Second the DB insert function:
function Write-CitrixLicense {
BEGIN {
# Open the DB Connection
$conn = New-Object System.Data.OleDb.OleDbConnection
$connstr = "Your connection string"
$conn.connectionstring = $connstr
$conn.open()
# create DB command
$cmd = New-Object system.Data.OleDb.OleDbCommand
$cmd.connection = $conn }
PROCESS {
# create the INSERT statement using object properties
$now = Get-Date -form g
$sql = "INSERT INTO tblCitrixLicense (Server,Count,InUse,
SubmitDate) VALUES ("
$sql += "'" + $_.Server + "',"
$sql += "'" + $_.Total + "',"
$sql += "'" + $_.InUse + "',"
$sql += "'" + $now + "')"
$cmd.commandtext = $sql
$cmd.executenonquery() Out-Null }
END {$conn.close()}
}
Finally the call....
'Server1','Server2' %{Get-CitrixLicenses} Write-CitrixLicense
