Multi-dimensional Tables - SNMP Data Query Walkthrough

Post by stx73 »

Hi all, any advanced user who can help me out there?

From file TIMETRA-NAT-MIB.mib here's the definition of the tmnxNatIsaResrcStatsTable table:

Code: Select all

[size=85]tmnxNatIsaResrcStatsTable   OBJECT-TYPE
    SYNTAX      SEQUENCE OF TmnxNatIsaResrcStatsEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
       "..."
    ::= { tmnxNatIsaMdaStatObjs 4 }

tmnxNatIsaResrcStatsEntry   OBJECT-TYPE
    SYNTAX      TmnxNatIsaResrcStatsEntry
    MAX-ACCESS  not-accessible
    STATUS      current
    DESCRIPTION
       "..."
    INDEX { tmnxChassisIndex,
            tmnxCardSlotNum,
            tmnxMDASlotNum,
            tmnxNatIsaResrcStatsId }
    ::= { tmnxNatIsaResrcStatsTable 1 }

TmnxNatIsaResrcStatsEntry ::=
    SEQUENCE {
        tmnxNatIsaResrcStatsId           Unsigned32,
        tmnxNatIsaResrcStatsName         DisplayString,
        tmnxNatIsaResrcStatsValMax       CounterBasedGauge64,
        tmnxNatIsaResrcStatsValMaxLw     Gauge32,
        tmnxNatIsaResrcStatsValMaxHw     Gauge32,
        tmnxNatIsaResrcStatsVal          CounterBasedGauge64,
        tmnxNatIsaResrcStatsValLw        Gauge32,
        tmnxNatIsaResrcStatsValHw        Gauge32
    }

tmnxNatIsaResrcStatsVal OBJECT-TYPE
    SYNTAX      CounterBasedGauge64
    MAX-ACCESS  read-only
    STATUS      current
    DESCRIPTION
       "The value of the object tmnxNatIsaResrcStatsVal indicates
        the actual value of the resource statistics
        contained in this conceptual row."
    ::= { tmnxNatIsaResrcStatsEntry 6 }[/size]
As you can see the index is made of four values:

Code: Select all

I need to create a proper file /var/www/html/cacti/resource/snmp_queries/tmnxNatIsaResrcStatsTable.xml to retrieve and display the values of the tmnxNatIsaResrcStatsVal column for every row and for every Card Slot number (4 in total.)

Below my first attempt:

Code: Select all

        <tmnxNatIsaResrcStatsVal>
            <name>Val</name>
            <method>walk</method>
            <source>value</source>
            <direction>output</direction>
            <oid>.1.3.6.1.4.1.6527.3.1.2.65.1.1.3.4.1.6</oid>
        </tmnxNatIsaResrcStatsVal>
    </fields>
</query>[/size]
But: I'm not sure this is the correct way to SNMP poll the device.

This is the Verbose Output:

Hi gandalf,

of course I read your manual, and without that I wouldn't have been able to create this XML file; but now I'd like to add some columns (input fields) in the selection table (in addition to tmnxNatIsaResrcStatsName: .1.3.6.1.4.1.6527.3.1.2.65.1.1.3.4.1.2), in particular:

tmnxChassisIndex: .1.3.6.1.4.1.6527.3.1.2.2.1.3.1.1
tmnxCardSlotNum: .1.3.6.1.4.1.6527.3.1.2.2.3.2.1.1
tmnxMDASlotNum: .1.3.6.1.4.1.6527.3.1.2.2.3.8.1.1
tmnxNatIsaResrcStatsId: .1.3.6.1.4.1.6527.3.1.2.65.1.1.3.4.1.1

because these are the (four) columns that DEFINE the INDEX of the entries in the tmnxNatIsaResrcStatsTable table.

The problem is that these last four OIDs are "outside" the <oid_index> range (which is .1.3.6.1.4.1.6527.3.1.2.65.1.1.3.4.1), and if I shorten the <oid_index> (in order to take into account these four OIDS too) I won't be able to use the <oid_index_parse>OID/REGEXP (which takes the last four OID octets from the snmpwalk) any more!

So how can I do? I searched the website and the web for similar problems, but the index is always simple (like ifIndex for example) or compound but in that case every input OID is always contained in the snmpwalk.

Any help would be very very appreciated :-)

Thanks,
Stefano

Currently, you can only tackle the index as a single object of it's own. You can't combine multiple indexes!
When dealing with multi-level-indexes, understand them like a strin index of type "i.j.k.l" for example. Thus, when creating the Data Query select table (for "Create Graphs for this Host"), it is a single index column only! It will then list all available tupels of type "i.j.k.l" and you may select those you need.
Else, you will have to use a script. There you may do whatever you want ...

I am very interested in how to do this.

Is there a sample script that shows how to do this?
