Hi,
I wrote a script to get a linux file size as the following json. It works fine with the script verification and realtime value showed in the DP Details screen. However no value is recorded in the history, only a question mark(?) is shown along with the timestamp. The weird thing is that the cached values showed in the datapoints details are displayed correctly as you can see in the screenshot above, but when I update the screen, the values became do a question mak again.
What I am missing?
Thanks in advance
