SNMP MIB Files

[jluvs2ride]

So, I'm using the APC PDU New SNMP Template.

https://share.zabbix.com/power-ups/apc/apc-pdu-new-snmp-template

I copied the MIB file to /var/lib/snmp/mibs/ietf/ (this is a proxy running on a Raspberry PI). I commented out the line in the snmp.conf file.

All the items for the SNMP devices using this template give the "SNMP error: (noSuchName) There is no such variable name in this MIB." error.

I have the SNMP packages installed. Is there something I have to do to link the MIB file to the template?

Try installing and using an MIB Browser like iReasoning and see if you can actually do a GET, GET BULK or GET SUB-TREE for those OIDs from your device. If you can't then those OIDs are not supported by your device.

Thanks for your response. I downloaded the MIB from the manufacturer for this device. Browsing the MIB file I can see the OIDs. Do the SNMP support software and MIBs need to be installed on the Server or the Proxy?

[myRCzabbix]

What I actually meant is to test from your workstation if you could actually get a value for those OIDs. The MIB files essentially translate the OID numbers to a string (I am oversimplifying). What I was suggesting was you test first if the OIDs you have actually exist on the device you are trying to monitor. They may not be existing/supported by the device.

I do understand what you're saying, but I only have the SNMP packages and MIB files installed on the Proxy. I'm thinking the SNMP packages and MIB files should be installed on the server.

I don't think you do. The message you are encountering either means you don't have access to the OID, you are querying for an incorrect OID (hardly the case since it's from a template that is known to work by others), or the OID you are querying doesn't actually exist/is not supported by the device. This is why I was asking if you could test it first.

Not sure why you are obsessed with where to put the MIB files. It won't matter whether you put them in the proxy or the server if either one of the three possible causes above is true.

Here's a screenshot of me querying a printer for OID .1.3.6.1.2.1.43.11.1.1.6.1.1.



As you can see, there's a result. Now if I were to query for OID .1.3.6.1.2.1.43.11.1.1.6.1 (missing the last .1), here's what I get



The error message (which is the same as yours) tells me the device doesn't have that OID.

What I was asking you to do is to do a walk so that you would get something like the one below where it lists down all the OIDs the device supports.

I did the SNMP walk and snmp get on the proxy to query the device in question. The OIDs I was looking for were not found.

Then it doesn't support the specific OIDs you were looking for.

Your next step would be to figure out which OID in the device would give you the same information as the OID you got from the template and change the those OID entries in the template.

[jluvs2ride]

Yeah, I don't get it. The MIB was supposed to be for that specific hardware. I changed templates and I have the info I want.
