poller errors

[grank]

can you tell me if the errors below when I run the poller manually pertain to the cacti server or are they in response to the snmpd.conf from the host I am monitoring with cacti? I have 4 hosts currently setup to monitor. The only info that graphs for each host is disk, processes and users...I need cpu, memory and network info to graph also...thanks. If you need more info or logs let me know. Greg

Looks like you are polling with an invalid OID number on the host.

You can check what OID number you need to use on the host with snmpwalk.

[gandalf]

These OIDs are part of the UCD-SNMP MIB. Perhaps your target does not support this MIB. You may try the HOST-RESOURCES MIB, OIDs .1.3.6.1.2.1.25

snmpwalk returns the following on host and target:

You queried system OIDs. That's fine to see, that the host responds. But you may have to change the remote snmpd.conf (or the like) to respond to queries asking for disk, CPU and the like. Normally, this can be done using the OIDs I posted above. But you may have to check the system's docs to verify, that this is possible (not all systems support the host or UCD MIBs)

Thank you very much for the reply...
I am fairly new to snmp and doing tutorials etc..

I have played around with snmpconf -g basic_setup but it did not have options for cpu, memory and network interface traffic...

Any chance you can look at this attached snmpd.conf file (this is from RedHat AS3.0 server) and give me an example of what to change to allow it to respond to cpu, memory and interface traffic?

What would be most useful to me is a copy of an snmpd.conf file from someone (even Cacti)
that works with all the OID querries that Cacti makes...
It would be nice if Cacti supplied an snmpd.conf that would respond to all
of it's querries.
Thanks

How can i get the oids of remote server because i think the oids in my cacti ui for remote server are wrong thats why i am not receiving the data

[gandalf]

There are some standard MIBs that are mandatory for SNMP agents, e.g. the interface MIB (in Cacti: SNMP - Interface Traffic).
Then there are lots of non-mandatory MIBs like e.g. the Host MIB.
And then there are private MIBs, implemented by vendors solely to support their own devices.
