No. Its irrelevent. The underlying issue is that the command line works but cacti will not return query results, no matter whether its v1 or v3 or what host I make the query against.
In a PM conversation, I was also asked for the following detail. Here is the XML file for the query I am writing (v3) and the associated command line data:
Code: Select all
<interface>
<name>Get SNMP Fan Speed</name>
<description>Queries an SS4200-E for a list of internal fans</description>
<oid_index>.1.3.6.1.4.1.1139.10.6.1.1.1</oid_index>
<oid_num_indexes>.1.3.6.1.4.1.1139.10.6.1.1.1.3</oid_num_indexes>
<index_order_type>numeric</index_order_type>
<fields>

<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.1139.10.6.1.1.1</oid>
</fanIndex>
<fanName>
<name>Name</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.1139.10.6.1.1.2</oid>

<direction>output</direction>
<oid>.1.3.6.1.4.1.1139.10.6.1.1.3</oid>
</fanSpeed>
</fields>
</interface>
Also so you can see what the output would be expected to be:

Here is essentially the same functionality, done as a PERL script invoking the command line net-smtp tools which
does work. Beautifully, in fact.
