Problem "SNMP error" whereas graphs are generated

[blueman176]

Hello,

In the "devices" tab, I have a message "SNMP error". And logs show that the default SNMP timeout (500ms) is reached.
But all my graphs are well generated! And all devices are "Up". I set "Downed Device Detection" to "Ping and SNMP".

Why I have the message "SNMP error" for each devices whereas snmpwalk works well and graphs are generated?

Thanks

Nobody knows what's happened?

Try this command:
% snmpget -v <Your_SNMP_Version> -c <Your_SNMP_Community> <Target> .1.3.6.1.2.1.1.1.0
(.1.3.6.1.2.1.1.1.0 = sysDescr.0)

If this failed, Cacti shows "SNMP error" in device setting screen.

But in devices list screen, it seems that Cacti uses this OID for checking SNMP: ".1.3.6.1.2.1.1.3.0" (sysUpTimeInstance) -- probably. (not fully verified, sorry)
(And this status is updated at the time which poller runs)

Does your SNMP agent respond to both OIDs?

Thanks for the answer.

The both OIDs work well with the snmpget command.

Thanks for the answer.

The both OIDs work well with the snmpget command.

This is which version of cacti? Please show output of both snmpget commands (NOT snmpwalk!)
