/chart error with OH2 on Synology DSM 6

Desh · August 15, 2017, 7:55pm

Hi,

I’m trying to get some rrd4j charts rendered on my OH2 Synology Diskstation, but get the following errors in openhab.log instead. My set-up is OH2 2.1.0.008 on a DS216+ with DSM 6.0.3-8754 Update 4. Any ideas how to fix it (Oracle Java 8.0.121-0013 installed)?

sitemap line: Chart item=Result period=D

Meanwhile I played around with different set-up etc. and found out, that rrd4j is not running. No wonder that /chart is not working.

The thing is: I’ve installed it via Paper UI, set rrd4j as default persitence service in Configuration>System and used the same rrd4j.persist file I use on my raspberry.

I’m thankful for every hint I get.
