Mutiple channel with vbscript



I use vbscript and my code is that:

strComputer = ""

' Leave User and Password blank for local machine

strUser = ""
strPassword = ""

strNamespace = "root/cimv2"

Set objLocator = CreateObject("WbemScripting.SWbemLocator")
Set objWMIService = objLocator.ConnectServer(strComputer,strNamespace,strUser,strPassword)
Set objTimeZone = objWMIService.ExecQuery ("SELECT * FROM Win32_TimeZone")

For Each colTimeZone in objTimeZone
  strBias = colTimeZone.Bias
  strStandardname = colTimeZone.Standardname
wscript.echo "<?xml version=""1.0"" encoding=""UTF-8"" ?>"
wscript.echo "<prtg>"
wscript.echo "<result>"
wscript.echo "<channle>" & strBias & "</channel>"
wscript.echo "<value>test123</value>"
wscript.echo "</result>"
wscript.echo "<result>"
wscript.echo "<channle>" & strStandardname & "</channel>"
wscript.echo "<value>test234</value>"
wscript.echo "</result></prtg>" 

but it return error, the error message is

"Response not wellformed: "(<?xml version="1.0" encoding="UTF-8" ?> <prtg> <result> <channle>-480</channel> <value>test123</value> </result> <result> <channle>Pacific Standard Time</channel> <value>test234</value> </result></prtg> )" (code: PE132)"

what wrong with my code?

Hello a23554,
thank you for your Knowledge base Post.

There are two issues in the output of your script, please check (I've formatted the output accordingly for increased legibility):

<?xml version="1.0" encoding="UTF-8" ?>
		<channle>Pacific Standard Time</channel>
  • The </channel> tag is misspelled as <channle>.
  • The content of the <value> tag MUST be numerical, 123 would be OK but test123 is a String and will cause error PE132 as well..

For more information, see PRTG Manual: Custom Sensors

Alternative you could use the WMI sensors with custom strings or custom numeric values to accomplish the same and not having a specific VBscript wrapped around it.

If you want to have text in your output, there is a <text> tag available for XML - but be aware - the text is not per result, it is a per script tag - so only one text-output in your whole XML response.

You further have some kind of a flaw in your VBscript here:

For Each colTimeZone in objTimeZone
  strBias = colTimeZone.Bias
  strStandardname = colTimeZone.Standardname

This will run through all objTimeZone objects / I am not clear if there is a possible collection - but if there is - so more then one "row" in your WMI query, you would only see the final result / row data.

Depending on what you want to accomplish, you might need to adjust this - cause every colTimeZone will overwrite your values in strBias and strStandardname.
