no data received for OID, but CLI works fine.

Hi,

I've a strange problem, and I assume I'm at fault.

I'm running 1.6.1 on Ubuntu 8.04 .. and have proxies on other ubuntu servers.

I'm trying to graph a device, and the particular OID I'm trying to get data from won't work in Zabbix.

On the CLI I do:-

snmpget -v1 -c <my-community> <device-IP> <OID>
SNMPv2-SMI:: <OID> = INTEGER: -51

which is fine, although the only funny thing about it it ... the result seems to be from a v2 MIB, whereas the command uses "-v1", and won't work with "-v2c"

Anyway, that looks like it works ... so I try add that to zabbix.
I add the host, then I add an item to that host

Description: <anything>
type: SNMPv1 agent
SNMP Community: <my-community>
SNMP OID: <OID>
port: 161
key: <OID>
type: Numeric(int 64bit)

but I don't receive any data from the device/OID!?

Is this the correct procedure? Am I missing something? I use the OID for the "key" value, is that correct?

I'll keep digging ...

thanks

Hi eoinverling,

As I understand it, the OID should work as the key, but I would replace it with SNMPv2-SMI:: <OID>.

I usually use things like these for the key:
ifAlias.4
tcpConnState.0.0.1825
etc.

You should be able to snmpwalk both the OID and the key, and get the same result.

Some questions:

1. Is Zabbix configured --with-net-snmp ?

2. Is there anything in Zabbix_Server.log? Also, look at Conf --> Items, is there an error for this particular item?

3. Is this host successfully monitoring other snmp items?

Meanwhile, keep digging....

MrKen ... thank you very much!

... this should be put in the manual!!

So, I got it sorted, thank you.

Another thing I notice, which I didn't have the patients for before. Once I add an item to be graphed, it takes about 5 to 10 minutes (haven't timed it exactly) for the info to populate. I was loosing patients with that before, and assuming it wasn't working.

I'm delighted now ... cept I've loads of devices to configure!!

thanks again
