I retrieve datas from industrial automates. Most of these datas are booleans.
I use a GELF UDP Input to retrieve them.
I just see that if a field’s value is not changed since the “-1” input, the system send me nothing. But to have something usefull, I need to display either the sum of the last values, nor their average, but indeed the last value (either from the flow, ie the last known value)
Does somebody have an idea to do this ?
