I am interested in adding a modeler plugin that can cope with an SNMP table that has 2 different indices. I guess this would be considered a sub-component in the Zenoss framework which I am not sure exists. For example, I have a MIB that contains a table of Environmental Monitoring Devices (EMDs). They in turn can contain multiple Digital I/Os (DIO's). Here is a snippet from my MIB.
ogEmdDioTable OBJECT-TYPE SYNTAX SEQUENCE OF EmdDioEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Ths Digital I/O status table." ::= { ogStatus 12 }
ogEmdDioEntry OBJECT-TYPE
SYNTAX EmdDioEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "Digital I/O status entry" INDEX { ogEmdIndex, ogEmdDioIndex } ::= { ogEmdDioTable 1 }
EmdDioEntry ::= SEQUENCE {
ogEmdDioIndex Integer32, ogEmdDioEmd OBJECT IDENTIFIER, ogEmdDioName DisplayString, ogEmdDioDescription DisplayString, ogEmdDioType INTEGER, ogEmdDioDirection INTEGER, ogEmdDioState INTEGER, ogEmdDioTriggerMode INTEGER, ogEmdDioCounter Counter32
}
ogEmdDioIndex OBJECT-TYPE
So the EMD table is straight forward to model however I have not been able to find an interface that can deal with the 2 indices that are used for EMD DIO entries. The snmpGetTableMaps member of SnmpPlugin only seems to handle 1 index, is there an existing plugin interface that can do this or Is a Sub-Component something I can extend zenoss to support?
