Rrd4j and mapdb persistence wont log group items in openhabian

fried_chicken · August 1, 2017, 11:26am

im moving from a 1.8 install to run on the latest openhabian version and all is good except for persistence!

in my rrd4j.persist file i have:

// persistence strategies have a name and a definition and are referred to in the “Items” section
Strategies {
// for rrd charts, we need a cron strategy
everyMinute : “0 * * * * ?”
}

Items {
Chart_Weather* : strategy = everyMinute, restoreOnStartup
Temperature : strategy = everyMinute, restoreOnStartup
}

the ‘Temperature’ item is working fine and logging every minute (checked the debug log and file timestamp)

the issue is the groups - the just aren’t logging. nothing is displayed in the debug.
i’ve tried with and without the asterisk no difference.

this works fine in 1.8 - i can’t find anything telling me oh2 is different.

can anyone please help? thanks!

Please can you show the definition of item und group for Chart_Weather.
If you copied it from demo.items the name is Weather_Chart.

to try to troubleshoot i only added one item to the group:

Group Chart_Weather
Number Temperature “Temperature [%.2f °C]” (Chart_Weather) {weather=“locationId=home, type=temperature, property=current”}

This will save the item Temperatue 2 times.
What happens if you use only

Chart_Weather* : strategy = everyMinute, restoreOnStartup

thats the problem - its not!
its not logging for the group

i added the item ‘Temperature’ just to prove that it does actually work - i get this in the debug logs as expected:
14:07:00.018 [DEBUG] [sistence.rrd4j.internal.RRD4jService] - Stored ‘Temperature’ with state ‘21.00’ in rrd4j database

if i just have the group ‘Chart_Weather’ in the rrd4j.persist file then nothing gets written to the debug log and the database file does not get updated.

i get the exact same issue with mapdb - maybe this is a bug with this version of oh2?

Groups which shall be persisted have to be set to an item Type, so please define the Group as

Group:Number Chart_Weather

fried_chicken · August 1, 2017, 2:00pm

ok i tried changing the item file to:
Group:Number Chart_Weather

but still the same - nothing getting logged.

has the format on this changed between oh1 and oh2? i’ve not found any documentation to say about the change?

i read more on the group types - but i don’t understand how this is needed for persistance. for example what i was doing with mapdb was to create a standard group containing all my plug sockets and persist that. i wasn’t trying to do an OR,MAX,MIN functions etc on them.

My example works (2.2.0-SNAPSHOT Build #988)

Group Chart_Weather
//Number Temperature "Temperature [%.2f °C]" (Chart_Weather) {weather="locationId=home, type=temperature, property=current"}
Number Temperature1 "Outside Temperature [%.1f °C]" <temperature> (Chart_Weather)	{ channel="yahooweather:weather:berlin:temperature" }
Number Sun_Elevation1 "Sun Elevation" <sun> (Chart_Weather) { channel = "astro:sun:home:position#elevation" }Contact c1
Contact c2
Contact c3

Strategies {everyMinute : "0 * * * * ?"}
Items {
 Chart_Weather*, Temperature1, c1 : strategy = everyMinute, restoreOnStartup
 Chart_Weather*              , c2 : strategy = everyMinute, restoreOnStartup
                 Temperature1, c3 : strategy = everyMinute, restoreOnStartup
	}

Check your quotation marks and change it from

to

Do you not use the SmartHome-Designer?

after changing the quotation marks it works
