Cacti does not generates graphs after installation
Introduction
Versions: EyesOfNetwork >= 5.3
EyesOfNetwork provides Cacti usage to generate bandwidth graphs, especially for network devices. After adding your equipments, and check SNMP polling is OK, graphs are not generated.
We can see in logs /srv/eyesofnetwork/cacti/log/cacti.log
the following errors:
