Attached poller.php -d for one of the devices
RRD /opt/observium/rrd/device.net.ad.customer.se/ping.rrd already exists - no need to create.
ERROR: rrdcached: RRD Error: opening '/opt/observium/rrd/device.net.ad.customer.se/ping.rrd': No such file or directory
”rrdtool info” gives me:
root@server:/opt/observium# rrdtool info --daemon device/ping.rrd
ERROR: rrdcached: No such file: /opt/observium/rrd/device/ping.rrd.
The same command for uptime.rrd works

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
Some information regarding my system
Observium 18.7.9354 (30th July 2018)
OS Linux 4.4.0-130-generic [amd64] (Ubuntu 16.04)

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
