hello ,
according to “Setting up RRDCached” article rrdcached supports creating rrd files over rrdcached. i did every single step on “Distributed Poller” article but i could not manage get rrd graphs running. it always gives me “error drawing graph” error.
if i choose/add nfs server-client method to my servers everything goes back to normal.
but article says sharing file system is not required anymore!! i dont get it
here is my config
