No stats anymore

[Yzord]

My proxmox (3.4-6) does not show any statistics anymore, like CPU, memory usage, server load etc.)

I restarted several pve services, but i remains silent. Anyone knows how to fix this?

Also did

# service pve-cluster restart
# service pvestatd restart
# service pvedaemon restart
# service apache2 restart

But no graphs are showing

Is system time correct and in sync on all nodes?
