Custom Script / Data Query

[voltsz]

Hy,

I follow the guide on http://docs.cacti.net/manual:087:3a_adv ... alkthrough and build a custom XML file and custom IOD request, but when I run the "Verbose Query" I receive "No SNMP data returned".

And I googled and searched on this forum without result... And I'm asking to yours a solution...

The remote SNMP host is cofigured as follow:

Code: Select all

pass .1.3.6.1.4.1 /usr/bin/perl /opt/3pp/bin/snmp/MD.pl

The XML is:

Code: Select all

<interface>
        <name>Get Information</name>
        <description>Get SNMP based</description>
        <index_order_type>numeric</index_order_type>
        <oid_index>.1.3.6.1.4.1.1</oid_index>

        <fields>
                <Index>
                        <name>Index</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.4.1.1</oid>
                </Index>
        </fields>
</interface>

The CLI snmpwalk from CACTI server is:

Code: Select all

snmpwalk  -v 2c -On -c public X..X.X.X .1.3.6.1.4.1
.1.3.6.1.4.1.1.1 = INTEGER: 1
.1.3.6.1.4.1.1.2 = INTEGER: 2
.1.3.6.1.4.1.1.3 = INTEGER: 3
.1.3.6.1.4.1.2.1 = STRING: "ID1"
.1.3.6.1.4.1.2.2 = STRING: "ID2"
.1.3.6.1.4.1.2.3 = ""
.1.3.6.1.4.1.3.1 = STRING: "6"
.1.3.6.1.4.1.3.2 = STRING: "6"
.1.3.6.1.4.1.3.3 = ""
Timeout: No Response from X..X.X.X

And under "Data Query Debug Information" I have:

Code: Select all

+ Running data query [18].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/usr/local/cacti-0.8.7e/resource/snmp_queries/MD.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.1'
+ No SNMP data returned

+ Found data query XML file at '/usr/local/cacti-0.8.7e/resource/snmp_queries/MD.xml'

I appreciated any help.

Thanks

You are missing an output field definition.

You are missing an output field definition.

Thanks. But I'm lost. I following the instruction on manual, I wrote a XML definition as depicted on the help, payed attention on index OID.

Sorry but I did not found what I'm missing.

Thanks

When I'm writing data queries, I always look at the interface data query and resource file as a reference. Maybe this will help?

[voltsz]

Hy Rony,

no. Maybe it's better to crash my brain on the wall. But I don't understand.

I followed the manual but I did not understand. Sorry

Try the following XML:

Code: Select all

<interface>
        <name>Get Information</name>
        <description>Get SNMP based</description>
        <index_order_type>numeric</index_order_type>
        <oid_index>.1.3.6.1.4.1.1</oid_index>

        <fields>
                <snmpIndex>
                        <name>Index</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.4.1.1</oid>
                </snmpIndex>
                <snmpName>
                        <name>Name/name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.4.1.2</oid>
                </snmpName>
                <snmpValue>
                        <name>Value</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>output</direction>
                        <oid>.1.3.6.1.4.1.3</oid>
                </snmpValue>
        </fields>
</interface>

Thanks for the hint, but didn't work:

Code: Select all

I'm concerned with why there is "No SNMP data returned".

[voltsz]

Hy rony,

I'm concerned with why there is "No SNMP data returned".

mee too. That's happe because at the end of the SNMP query there is a timeout? On the CLI the SNMP-walk return this

Code: Select all

snmpwalk  -v 2c -On -c public X..X.X.X .1.3.6.1.4.1
.1.3.6.1.4.1.1.1 = INTEGER: 1
.1.3.6.1.4.1.1.2 = INTEGER: 2
.1.3.6.1.4.1.1.3 = INTEGER: 3
.1.3.6.1.4.1.2.1 = STRING: "ID1"
.1.3.6.1.4.1.2.2 = STRING: "ID2"
.1.3.6.1.4.1.2.3 = ""
.1.3.6.1.4.1.3.1 = STRING: "6"
.1.3.6.1.4.1.3.2 = STRING: "6"
.1.3.6.1.4.1.3.3 = ""
Timeout: No Response from X..X.X.X

That's the problem?

[voltsz]

I have found where was the problem!

The OID I used ( .1.3.6.1.4.1.1 ) was occupied by superior OID. If a search for ".1.3.6.1.4.1" under ~cacti/resource/snmp_queries I found several XML file where this OID was used, for example:

f5_bigip_ifStat.xml
f5_bigip_pm.xml
f5_bigip_pool.xml
f5_bigip_vs.xml
f5_gtm_poolStat.xml
f5_gtm_wip.xml
kbridge.xml
net-snmp_disk.xml
netware_cpu.xml
netware_disk.xml

When I changed the OID used under XML and GUI (I used for example ".1.3.6.1.4.1.9900.1") I have positive match:

Code: Select all

+ Running data query [18].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/usr/local/cacti-0.8.7e/resource/snmp_queries/MD.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.9900.1.1'

+ Located input field 'snmpIndex' [walk]

+ Located input field 'snmpName' [walk]
+ Executing SNMP walk for data @ '.1.3.6.1.4.1.9900.1.2'
+ Found item [snmpName='ID_005_1'] index: 1 [from value]

+ Found data query XML file at '/usr/local/cacti-0.8.7e/resource/snmp_queries/MD.xml'

+ Found data query XML file at '/usr/local/cacti-0.8.7e/resource/snmp_queries/MD.xml'

Maybe the OID used at beginning make confusion in CACTI when walk throught name and value.

What do you think?

However, thanks for helping!
