rrd file not updated

[staieb]

good afternoon,

i need your help guys, we have rebooted our linux machine due to some firmware upgrade. once we have done this, our cacti server was no longer updating the rrd files.

from cacti logs, i can see that data are pooled:

the other problem is that i'm adding 31 hosts but the poller is only pooling 2 hosts.

i have also tried to add and delete graphs from cacti web interfacce but the rrd file is not added nor deleted.

the right on this file are ok

can you please advise?
it is very critical for our business !!!
