But there's one sound
That no one knows
What does the fox say?

I mean... what does the log say... ?
Have you verified credentials for all devices? It should be visible from logs, if there are some devices which get to disabled state and back later...

[emaus]

the fox says nothing, there are no errors in the log
but if you do the test, then the data is there, but they are not on the chart

What is the preprocessing step configured for the item?

did not quite understand the question)

if you restart the service, all graphs are drawn normally, but then the data disappears
but some charts work fine

Right, missed that from the picture.

So emaus, if you want continuous graphs, start with removing the preprosessing rule that discards data.

Removed from template "discard unchanged with heartbeat" and everything worked out
