Please help with nfsen netflow tab is not graphing

when i clicked to rrd comand i getting this error, my graphs are empty, but in fw2.rrd is data.

ERROR: rrdcached: /data/nfsen/profiles-stat/live/fw2.rrd: Permission denied

my permissions
-rwxrwxrwx 1 www-data www-data 2687848 Sep 25 16:20 fw2.rrd

please help

So ok i disabled rrdcached and it is working, but is there a way how to use rrdcached with netflow addition ?

I’m guessing you have a permissions issue between the files and rrdcached. Setting nfsen to use rrdcached would probably be the pest bet.
