'Healthcheck' cmdlet needed

[leshkinski]

We need a cmdlet that would go over all key areas of the pull server config and report any anomalies to speed up troubleshooting in the future.

So I sourced this little tidbit from: http://blogs.msdn.com/b/powershell/archive/2014/05/29/how-to-retrieve-node-information-from-pull-server.aspx

function QueryNodeInformation
{
  Param (     
       [string] $Uri = "http://localhost:7070/PSDSCComplianceServer.svc/Status",                         
       [string] $ContentType = "application/json"          
     )
  Write-Host "Querying node information from pull server URI  = $Uri" -ForegroundColor Green
  Write-Host "Querying node status in content type  = $ContentType " -ForegroundColor Green


 $response = Invoke-WebRequest -Uri $Uri -Method Get -ContentType $ContentType -UseDefaultCredentials -Headers @{Accept = $ContentType}

 if($response.StatusCode -ne 200)
 {
     Write-Host "node information was not retrieved." -ForegroundColor Red
 }

 $jsonResponse = ConvertFrom-Json $response.Content

 return $jsonResponse

}

To get this to work, I had to create an http binding listening for requests on localhost:9081 on the PSDSCComplianceServer site. We can use this to pull the status code, heartbeat, last runtime, etc. Tie this in with a SNS or other notification system and we can follow client provisioning to ensure it does not fail.
