Do have a running setup with a few databases. I am fine with persistence strategy for most databases. But for 2 of them I want to have something else. I need better time resolution for the first 12h (instead of just 1 hour). I read about [image] rrd4j - Persistence Services The rrd4j per…

[image] starbright: Can this modification be done in Web-IF or in console? According to the docs the default resolutions are: It defines 5 archives: granularity of 10s for the last hour granularity of 1m for the last week granularity of 15m for the last year granularity of 1h for the last 5…

Thank you - think I almost understand. But I am confused about what <dsName> is and whats than a <dsName>.item ? My item is sm_consumption /etc/openhab/services/rrd4j.cfg : sm_consumption.def=GAUGE,10,0,U,10 sm_consumption.archives=AVERAGE,0.5,1,4320:AVERAGE,0.5,6,10080 according to my underts…

[image] starbright: But I am confused about what <dsName> is It’s what ever you want it to be. It’s what tells rrd4j that these three lines of config go together. It’s just a unique identifier. That’s why I used “foo12h” above. It just doesn’t matter so long as the three config lines match. …

My understanding was that (if this both archives - every 10s and every min) is full, so after 1 week, old data will be overwritten. That is ok for this example, but I might change that, true.

I have changed the default_numeric archive but this only affected the items that are created virtually or are bound to things and items in the the “item” folder. But I use two addons (for TPLink Tapo for example) these are not affected by the default archive strategy. But Im not able to find any con…

should I open a new thread for that question? I also found out that the graphs dont use the new values as well. Is there another setting that must be done so that the graph will also use the increased size of the archives?

I’ve never adjusted the rrd4j policies from the default so I don’t know anything about that beyond the docs which I assume you already read. But charting, rules, the API all use the same interface to all the databases. If what you are expecting to see isn’t coming up in your charts, it’s because the…

I actuall did open a new thread :X [image] Rrd4j.cfg persistence configuration does not apply to manually created items Items & Sitemaps Hi, I have changed the rrd4j.cfg to this: default_numeric.def=GAUGE,600,U,U,10 default_numeric.archives=AVERAGE,0.5,1,2160…

@opus was our resident rrd4j expert but he hasn’t been active on the forum for quite some time.

I have openhab 5.1.1 running on docker. My goal were slightly larger bucket lists for 10s and 1 min granularity. I placed the following rrd4j.cfg file into the directory \openhab_conf\services: test.def=GAUGE,1200,U,U,10 test.archives=LAST,0.5,1,4320:LAST,0.5,6,50400:LAST,0.5,90,36500:LAST,0.5,3…
