Data Query - Windows Server via SNMP

[mlmargotto]

I'm creating my first Data Query File to obtain the diskFree Statistics, via SNMP, from SNMP_Information_Standard package.

The XML code used:

<interface>
<name>Buscar por unidades logicas</name>
<oid_index>.1.3.6.1.4.1.9600.1.1.1.1</oid_index>
<index_order>dskIndex</index_order>
<index_order_type>numeric</index_order_type>
<index_title_format>|chosen_order_field|</index_title_format>
<fields>
<dskIndex>
<name>Index</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.9600.1.1.1.1.1</oid>
</dskIndex>
<dskFree>
<name>Disk Free</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.4.1.9600.1.1.1.1.20</oid>
</dskFree>
</fields>
</interface>

I create the Data Query and receive this information on Verbose Query

This result is OK but, if i want create graph for this host, only show me the logical volume D and _Total. The logical volume C doesn't show for me to create graph. Why?

Hello,

to implement the indexed Data Queries, you have to be very careful with the Index you use as the "primary key". It seems that both disks C and D have the same index, so probably they are the same physical disk but different partitions. You should try with other index or with other OID to walk, for example the SNMP Table for partitions or logical volumes that is what you really seem to be willing to check.

Hope this helps.

Best regards,

Fabio.

Aloha Fabio.

I make the SNMPWALK on Cacti linux server and get the real index.

Thanks!
