ADO SQL v2 Sensor showing error

Same issue here.

Hello,

We are able to reproduce this in the PRTG stable and Preview version and can confirm this is a current bug. We will be providing a fix for the same in a few days.

Please bear with us.

If anyone needs a ADO SQL sensor right now, I wrote a VBScript:

On Error Resume Next

Set objDBCommunicator = new DBCommunicator

Set objArgs 		= Wscript.Arguments
Set objConnection	= CreateObject("ADODB.Connection")
Set objRecordSet	= CreateObject("ADODB.RecordSet")

strPRTGStart 	=	"<prtg>"
strPRTGEnde 	=	"</prtg>"

Class DBCommunicator
	Public Function DBConnect(StrCon)
		On Error Resume Next
		
		objConnection.Open StrCon
		If Err.Number = 0 then
			DBConnect = True
		Else
			DBConnect = False
		End If
	End Function

	Public Function QueryDB(StrQuery)
		objRecordSet.Open StrQuery, objConnection
		If Err.Number = 0 then
			Do Until objRecordSet.EOF
				For each objField in objRecordSet.Fields
					If objField.Name = "" Then
						'Wscript.Echo "Wert" & " = " & objField.Value
						QueryDB = QueryDB	&	"	<result>" & VBCRLF
						QueryDB = QueryDB	&	"		<channel>" & strChannelNameCount & "</channel>" & VBCRLF
						QueryDB = QueryDB	&	"		<value>" & objField.Value & "</value>" & VBCRLF
						QueryDB = QueryDB	&	"	</result>" & VBCRLF
						'Wscript.Echo QueryDB
					Else
						'Wscript.Echo objField.Name & " = " & objField.Value
						QueryDB = QueryDB	&	"	<result>" & VBCRLF
						QueryDB = QueryDB	&	"		<channel>" & objField.Name & "</channel>" & VBCRLF
						QueryDB = QueryDB	&	"		<value>" & objField.Value & "</value>" & VBCRLF
						QueryDB = QueryDB	&	"	</result>" & VBCRLF
						'Wscript.Echo QueryDB
					End If
					
				Next
				objRecordSet.MoveNext
			loop
		Else
			QueryDB = QueryDB		&	"	<error>1</error>" & VBCRLF
			QueryDB = QueryDB		&	"	<text>Database Connect failed, please check parameters: " & chr(34) & "ADO SQL connectstring" & chr(34) & " , " & chr(34) & "SQL Query" & chr(34) & " , " & chr(34) & "Channel Name for Count" & chr(34) & "</text>" & VBCRLF
		End If
	End Function

	Public Function DBdisConnect
		objRecordSet.close
		objConnection.close
	End Function
End Class

Else

End If

wscript.echo strPRTGStart
wscript.echo strPRTG
wscript.echo strPRTGEnde

Maybe it helps as long as we wait for the fix.

Hi there We have the same issue

thanks Ash

I am now seeing that problem with PRTG Network Monitor 16.4.27.6720+

Please go to the sensor's settings, and Configure the "DEBUG OPTION" "Write sensor result to disk(Filename: Result of Sensor [ID].txt" The log will be written on the probe that monitors that sensor under (%ProgramData%\Paessler\PRTG Network Monitor\Logs (Sensors)) and send the result file to Support@paessler.com Please refer to this kB-article.
