Sensor factory error: "Formula empty"

Modified on 2025-06-10 21:55:30 +0200

PRTG version is 16.3.27.6636+ [Preview] I'm trying to create "factory" sensor with the folowing simple formula

1:Bitrate(123439,0) #2:Errors(123531,0)

And getting this: Error in channel list: Line 2, Channel #1:Bitrate(123439,0) #2:Errors(123531,0), Formula empty.

Can somebody point me to where my error actually is?

Hi there,

It seems that you wrote the formula one just one line, please use the following formula as an example:

#1:Sample
Channel(1000,0)
#2:Sample
Channel(1001,1)

Yes, this works. I forgot to include "Channel" keyword. Thank you.
