Hello,
I have a problem with graph generation. They are no longer being generated. I have checked the directory /var/lib/centreon/metrics and the .rrd files are present with the owner set as centreon-broker and the permissions set to -rw-r--r--. Additionally, I have regenerated the RRD databases from Administration => Settings => Data, but it still doesn't work. Moreover, all services are running fine and I don't see anything suspicious in the logs.
Thanks for your assistance.
