Hi,

rrd4j is not working for me. I get the following error - any ideas?

Thank you

Desh

openhab.log
[.p.rrd4j.internal.RRD4jService] - Removing invalid defintion component = null heartbeat = 0 min/max = 0.0/0.0 step = 0 0 archives(s) = [] 0 items(s) = []

openhab.conf
folder:persistence=10,persist
persistence:default=rrd4j

test.rules
Strategies
{
// for rrd charts, we need a cron strategy
everyMinute : "0 * * * * ?"
every10m : "0 0/10 * * * ?"
every15m : "0 0/15 * * * ?"
everyHour : "0 0 * * * ?"
default = everyChange
}

Items
{
Temperature : strategy = everyMinute, restoreOnStartup
}

test.items
Number Temperature “Temperature [%.2f °C]” {weather=“locationId=home, type=temperature, property=current”}

Why do you assume it’s not working?

That’s an info, not an error.

The filename has to be openhab.cfg

Try habmin and see if your are getting any rrd4j data …

Not to forget: The part under test.rules looks like persistence configurations, in that case the file has to be named rrd4j.persist, not test.rules!

Thanks for your quick responses, now it works.

@sihui: I had to install habmin first and never used it, sorry. Funny thing is, that after a reboot everything worked.

@Udo: Yes, you are right. I got a bit confused with the file names, but used the correct files.
