Cacti does not generate charts...

[batpax]

Hello everyone, I need help. Since yesterday cacti no longer generates graphs returning a series of errors that appear with Utility Systems > View Cacti Log File .
The server is standing for years and has never given any problems.
The implemented version is 0.8.8 and OS is CentOS

From the Cacti server, are you able to snmpwalk any of those hosts? My first guess would be new firewalls rules were introduced on your network that doesn't allow SNMP traffic through. Without more information, all I can really do is guess.

I tried using snmpwalk and it seems to work :

I can confirm that the new rules have not been implemented on the firewall. The server reaches all devive properly monitored.
I honestly do not know what to think !!!

Can anyone help me?
