Problem this snippet solves:

PowerShell script using F5 iControls that produces an email report of all ASM policies and what websites they protect. If a policy is enabled at the HTTP Class, it will be presented via a green table. Disabled policies will be presented via a red table.

Code :

# ==============================================================================================

# COMMENT: used on our 1600 running v11 to email out a weekly report of websites protected by the ASM

$g_bigip = "F5.domain.com" 

$g_email_to = "recipient@domain.com" 
$g_email_from = "ASM Policy Report "
$g_email_smtp = "smtp.domain.com"

Set-PSDebug -strict;

$ReturnValue = $b1.GetNetworkCredential().password
Return $ReturnValue
} # End Get-Logon Function

function Get-PolicyState($PolicyName){

    Add-PSSnapIn iControlSnapIn
  }
  $success = Initialize-F5.iControl -HostName $g_bigip -Username $g_uid -Password $PWD;
  return $success;
} # End Do-Initialize Function

Hi, I am getting the following:

 

Exception calling "get_host_match_pattern" with "1" argument(s): "Exception caught in LocalLB::urn:iControl:LocalLB/ProfileHttpClass::get_host_match_pattern() Common::NotImplemented " At C:\VM_shared\BIGIP\bigreport\4.2.1\asm_report.ps1:47 char:5 + $PolicyPatterns = (Get-F5.iControl).LocalLBProfileHttpClass.get_host_match_p ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : SoapHeaderException You cannot call a method on a null-valued expression.

Any Ideas?
