Zabbix 2.2.2, SNMP unsupported?

Added hosts with IP and port in "SNMP Interface" field. Added custom SNMP settings to connected template items. snmpwalk returns good values.

Result:


Why are they unsupported? What have I missed? SNMP data in overview returns "-".

I might add that the working items are ICMP pings that are running, no problem with those. I'm having a hard time diagnosing the problem, zabbix_server.log returns snmp fault with hosts that are unreachable by ping, but if Zabbix gives me a clue to why they aren't working, I'm missing it entirely.

How would I even troubleshoot this issue? I changed the way I input SNMP-community to no effect. Zabbix doesn't give me any SMTP-errors for hosts that aren't unavailable, other than that they are "not supported"

Could this be a trigger issue? I haven't defined any triggers for the SNMP data, I just want Zabbix to retrieve it and show it to me.

Increasing the loglevel, I get this nugget that is probably relevant:

  4529:20150508:111414.165 zbx_snmp_get_value() snmp_synch_response():0
  4529:20150508:111414.165 In zbx_snmp_set_result()
  4529:20150508:111414.165 End of zbx_snmp_set_result():NOTSUPPORTED
  4529:20150508:111414.165 End of zbx_snmp_get_value():NOTSUPPORTED
  4529:20150508:111414.165 In zbx_snmp_close_session()
  4529:20150508:111414.165 End of zbx_snmp_close_session()
  4529:20150508:111414.165 End of get_value_snmp():NOTSUPPORTED

I should mention I am using full OID's trying to retrieve information.

what are you using for your community? are you using the {SNMP_COMMUNITY} macro on the templates? have you defined that macro in Administration - General -Macros ?

[Anaythea]

I deleted the macro tag and just input the SNMP community straight into the template since we use the same community for the entire network. Think that might be a problem?

EDIT: Changed it, no difference. I'm checking over the OIDs again to see if they are the problem. Here are my results:


snmpwalk -v2c -c <> <> 1.3.6.1.2.1.1.4
= iso.3.6.1.2.1.1.4.0 = STRING: "Helpdesk 0000-0000000"

This is how the item looks like. Could the "key" be an issue? I have no idea what the purpose of that field is:

UPDATE:

Apparently you can't cheat your way out of installing every MIB in existance. I followed this guide and now supported items are steadily increasing:

i don't use mibs, even for my custom snmp stuff. i always use the oid, and not the human readable mib name. therefore, i don't have to bother loading all those mib files.

if your SNMP OID is defined using a mib name, and you don't have the appropriate mib files loaded, that will definitely cause an issue trying to translate them to an OID.

the KEY field is a unique identifier for that checked item. you reference that key elsewhere in zabbix to create triggers, graphs, etc based on the data returned.
