Hi,

I seem to have a strange bug with the weathermap. For some reason some links are calculated incorrect. Please see below screenshots. I already tried to figure out what exactly happend (it seems that this started when I added some more graphs into cacti).

Below is the config. I played aout with the cacti_use_ifspeed/no_cacti_extra but it doesn't have any effect. What might be special is that the poller interval is set to every minute (5min cron interval) and cacti is collecting based on 1 minute and 5 minute invervall. However all graphs on the map are 1minute polling values.

# That's All Folks!
howardjones commented 5 years ago

Do you actually use Boost? If not, do you get the same issue without 

SET rrd_use_poller_output 1

at the top?

lichtl commented 5 years ago

I use boost. I will try to deactivate boost for testing and check.

howardjones commented 5 years ago

I suspect it's the combination of polling time not matching the cron time, and use_poller_output. I don't think I've ever tested that...

lichtl commented 5 years ago

I disabled boost and disabled rrd_user_poller_output and map now looks okay (I still see a slightly difference between the value on the map and on the graph (but maybe just related to the small time difference).

lichtl commented 5 years ago

I just changed cron time to 1 minute. But once I enable boost it breaks

howardjones commented 5 years ago

Hopefully I will try this setup over the weekend.

FredNeuberger commented 5 years ago

Hey Howard, did you have the chance to test this yet?

howardjones commented 5 years ago

No, and my dev box is dead and in pieces on my workbench this evening :-(

howardjones commented 5 years ago

Dead/dying mobo. New dev system ordered.
