Hi Andrei,
getting rrdcached working took me a little effort.
Two important points, the rrdcached socket must me accessible by the user your webserver is running as. This is most easily achieved by add '-s www-data' before the -l option, (substitute www-data for your webserver gid).
You can test this by switching user to www-data and running socat against the rrdcache socket.
*www-data@host:~$ socat - unix:/var/run/rrdcached.sockHELP10 Command overviewUPDATE <filename> <values> [<values> ...]FLUSH <filename>FLUSHALLPENDING <filename>FORGET <filename>QUEUESTATSHELP [<command>]BATCHQUIT*
Secondly you need to configure rrd's to be at a location such as /var/lib/rrdcached/db/observium, I have...
*// rrdcached settings $config['rrdcached'] = "unix:/var/run/rrdcached.sock";$config['rrd_dir'] = "/var/lib/rrdcached/db/observium";*
Hope this helps.
Regards,
Rob

Did you disable rrdchached in config.php, just stopping rrdchaced is not enough?

Why are you trying to use rrdcache?
Didn't you think of trying to make it work without rrdcached first?
Rrdcached is not part of the installation instructions.

Why do you have every cronjob set up twice?
