RRD4J Graph spamming Errors

max2 · May 16, 2018, 4:54pm

Hello,

I’m using RRD4J for “drawing” the temperature of my sensors in a graph.

First, everything works fine (without errors) and the graph is now also working, but the console is spamming errors.

==> /var/log/openhab2/events.log <==

2018-05-16 18:42:24.702 [vent.ItemStateChangedEvent] - temperature changed from 23.50 to 23.56

2018-05-16 18:45:42.341 [vent.ItemStateChangedEvent] - temperature changed from 23.56 to 23.62

2018-05-16 18:48:00.542 [vent.ItemStateChangedEvent] - temperature changed from 23.62 to 23.69

I’m not really sure where the charts are written out to but somewhere there is a /cart folder (or perhaps not) and the openhab user doesn’t have permission to create files in that folder. I don’t use the charting servlet so I don’t have a chart folder anywhere. So I’ll be of no further help.

openhab-cli has a reset-ownership option. If you run that it might fix the permissions for you.

Can anyone say me where i find this function?

If you install openhab via apt-get or are using openHABian just type openhab-cli reset-ownership on the command line.

I’ve used openhabian, but it’s not working
Unrecognised command: reset-ownership
Usage: openhab-cli command [options]

Ideas?

Just type openhab-cli and it will print the available options. If it isn’t listed then that is a new option only available in OH 2.2. You will have to do it by hand in that case.

sudo chown openhab:openhab /var/lib/openhab2
