Replace IP by DNS Name

$accessId = '##IP2DNS.ACCESSID##'
$accessKey = '##IP2DNS.KEY##'
$company = 'uclahealth'

$deviceID = '##SYSTEM.DEVICEID##'

$currentName = '##SYSTEM.HOSTNAME##'
$currentDisplayName = '##SYSTEM.DISPLAYNAME##'

if ($currentName -ne $currentDisplayName) {
  # do a patch here to update the Name
  # you need to patch to 
  # 'https://uclahealth.logicmonitor.com/santaba/rest/device/devices/$($deviceID)?patchFields=displayName'
  # and the payload of your HTTP request needs to have something like the following JSON:
  # {"displayName":"$currentName"}
  #Request Info
        $httpVerb = 'PATCH'
        $resourcePath = '/device/devices/128'
        $queryParams = '?patchFields=displayName'
        $data = '{"displayName":"$currentName"}'
  Send-Request $resourcePath $httpVerb $queryParams $data
  Write-Host "ip2dns.result=Changed IP $($currentName) to DNS $($currentDisplayName)"
} else {
  Write-Host "ip2dns.result=Did not change IP to DNS"
}

this is the current script, I think I am missing something ...

BTW when doing "test script" in the PropertySource does it write the machine used during the test?

Thanks,

Dom
