Ensure device RRD directory exists before polling it

I just noticed a device in one of my Observiums is missing its RRD directory, the poller just says

RRD STDOUT[ERROR: creating '/var/www/observium/rrd/host.example.net/status.rrd': No such file or directory]

Please ensure device directory exists before polling a device is performed?

If creating the directory fails, add to device event log an alert about it?
