can I get the key name from an oid

[jerrysu1981]

We have a device the can send the temperature to zabbix via snmp, we get the oid (temperature vaule) from the mib file which sent from the device vendor.
and we able the get the temperature by snmpwalk using that oid. but if I need add item on zabbix, that need key name which I dont have, (and vendor doesn't know too )
can I get the key name from an oid or can I get it from other way?
please check the details form attachment. thanks

Please freely set names that do not conflict with other item's key.
If the device vendor names the OID with an alphabetic character string, you can also match it.

And, I think that OID needs to be specified as follows.
.1.3.6.1.4.1.34672.20.1.3.1.1.1.0

UPD
First of all, the Item Key is just a UTF-string, unique within a single host. See Item key format in Zabbix Documentation.

Good practice is to use OID's literal name from MIB. You can extract it from the MIB-file provided by device vendor.

$ snmptranslate -m .snmp/mibs/UPS-MIB 1.3.6.1.2.1.33.1.2.5
UPS-MIB::upsBatteryVoltage

By the way, you can store your MIB-files in "/usr/share/snmp/mibs/" and "service zabbix-server restart" to allow Zabbix translate literal OIDs himself. See example from our Zabbix below.



Hint:
You can also extract all of existing OIDs from your MIB wih snmptranslate:

$ snmptranslate -Tz -m .snmp/mibs/UPS-MIB
...
"upsBattery"                    "1.3.6.1.2.1.33.1.2"
"upsBatteryStatus"                      "1.3.6.1.2.1.33.1.2.1"
"upsSecondsOnBattery"                   "1.3.6.1.2.1.33.1.2.2"
"upsEstimatedMinutesRemaining"                  "1.3.6.1.2.1.33.1.2.3"
"upsEstimatedChargeRemaining"                   "1.3.6.1.2.1.33.1.2.4"
"upsBatteryVoltage"                     "1.3.6.1.2.1.33.1.2.5"
"upsBatteryCurrent"                     "1.3.6.1.2.1.33.1.2.6"
"upsBatteryTemperature"                 "1.3.6.1.2.1.33.1.2.7"

I use a unique string on key, but still not work. check my configration via attachment

But..
your first question was:

... but if I need add item on zabbix, that need key name which I dont have, (and vendor doesn't know too )
can I get the key name from an oid or can I get it from other way?

And now you say that it "..still not work"

Ok, if it is still relevant..

• change Information type of Item to "Numeric (float)" bacause you have dotted number in snmpget output (if you use zabbix version before 3.x you will get UNSUPPORTED item error)
• show Item status in "Hosts > <your host> > Items" page Does it have any errors in Info column?
