Hi guys,
Hope someone here can shed some light on my issue with rrdcached and observium. I am using a distributed setup with web/sql/poller on separate machines. Followed the guide here http://blog.best-practice.se/2017/10/scaling-observium-horizontally.html and currently using two pollers with great success overall
What I can't seem to figure out is why some rrd files won't get created. It doesn't matter what poller I am using or what devices, it is always the following rrd-files ping.rrd ping_snmp.rrd status.rrd

I can manually create a rrd file from the poller with success rrdtool create device/status.rrd --daemon ip-address RRA:AVERAGE:0.5:1:2016 DS:status:GAUGE:600:-20000:U
