Can't get |query_field_name| variables to display

[acominoli]

I set up a data query and the values return correctly. But when I create a Comment item in a graph and specify Model: |pduModel| it shows exactly as typed to the left. It does not substitute the actual query variable.
XML file:
<interface>
<name>Get APC7900 Info</name>
<index_order_type>numeric</index_order_type>
<oid_index>.1.3.6.1.4.1.318.1.1.12.1</oid_index>

<fields>
<pduModel>
<name>Model</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.318.1.1.12.1.5</oid>
</pduModel>
<pduSerial>
<name>Serial Number</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>

Please use |query_pduModel| instead

I actually have it that way and that is what shows on the graph i.e. Model: |pduModel|

!) Which version of Cacti are you using, please?
2) Navigate to "System Utilities -> View SNMP Cache and search for the device and the pduModel. Do you find it here?

Yes it shows the following:

Host: GHC-SPDU , SNMP Query: AP7900 - Info
Index: 0 , Field Name: pduModel , Field Value: AP7900
OID: .1.3.6.1.4.1.318.1.1.12.1.5.0

Cacti Version 0.8.8a

Ah, got it.
Currently, you are using the last OID part as the index (just as "usually). But in fact, the last part always shows ".0". So, in fact, you should use the last two parts of the OID as the index, e.g. ".1.0", ".2.0", ".3.0" etc.
You will have to use a OID/REGEXP to do so. Search forums for multi-level indexes and/or 1st link of my sig
