Excluding DMX LED Pixels from RRD4J

I have a large number (100’s) of individually addressable LED Pixels on LED light strips that are regularly changing via DMX SACN binding.
It seems pointless having these values persisting and I am regularly getting the errors like below for each item on each change which is creating a lot of noise in my logs

Could not create rrd4j database file ‘/var/lib/openhab/persistence/rrd4j/RedStrip4Status.rrd’

These are defined as
Thing - dimmer RedStrip4 [dmxid=“402,406,410,414,418”, fadetime=1000]
Item - Dimmer RedStrip4Status “RedStrip3” { channel=“dmx:dimmer:myAirPix:RedStrip4:brightness” }

Is there a way to exclude these items from the RRD4J persistence whilst still allowing my other items to continue using the the default persistence ?


No, not as such.
Set up an rrd4j.persist file to manually describe what to persist (and restore), this will override the default ‘everything’ behaviour. Only what is described will be persisted.
People often use Groups to manage this easily.
