PB => XML and SNMP data query

[titou.tct]

Hi,
Excuse my english...
I try to get disk informations with SNMP.
Ucd/net-snmp disk uses uncorrect OIDs to scan my remote host.
My query seems to be OK (it's just an adaptation and there is no pb with debug) but it returns 0 rows and I don't know why.
I'm using Cacti-0.8.5

essai.xml
<query>
<name>Get Infos Partitions</name>
<oid_index>.1.3.6.1.2.1.25.2.3.1.1</oid_index>

<fields>
<dskIndex>
<name>Index</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.2.1.25.2.3.1.1</oid>
</dskIndex>
<dskType>
<name>Storage Type</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.2.1.25.2.3.1.2</oid>
</dskType>
<dskMount>
<name>Mount Point</name>
<method>walk</method>
<source>value</source>
<direction>input</direction>
<oid>.1.3.6.1.2.1.25.2.3.1.3</oid>
</dskMount>
<dskUnits>
<name>Allocation Units</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>1.3.6.1.2.1.25.2.3.1.4</oid>
</dskUnits>
<dskTotal>
<name>Total Space</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>1.3.6.1.2.1.25.2.3.1.5</oid>
</dskTotal>
<dskUsed>
<name>Used Space</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>1.3.6.1.2.1.25.2.3.1.6</oid>
</dskUsed>
</fields>
</query>

I'm beginner and the board is my main help, please don't let me down.

Taking a look at your screenshots, the debug output does not look correct. The first line that catches my attention reads:

Code: Select all

Found item [dskIndex='hrStorageIndex.1 1'] index: hrStorageIndex.1 1 [from value]

I am pretty sure that the index is supposed to be "1" and not "hrStorageIndex.1 1". It is possible that Cacti is having parsing problems, but that is unlikely considering that the other data queries are working.

Can you show me the output that results if you walk .1.3.6.1.2.1.25.2.3.1.1 at the command line? It would help to turn on numeric OID output (-O n) when doing this.

Thanks for the advice.
snmpwalk -c public 36.125.1.12 .1.3.6.1.2.1.25.2.3.1.1
hrStorageIndex.1 1
hrStorageIndex.2 2
hrStorageIndex.3 3
hrStorageIndex.4 4
hrStorageIndex.5 5
hrStorageIndex.6 6
hrStorageIndex.7 7
hrStorageIndex.101 101
hrStorageIndex.102 102
hrStorageIndex.103 103

and with -On
snmpwalk -On -c public 36.125.1.12 .1.3.6.1.2.1.25.2.3.1.1
hrStorageIndex.1 1
hrStorageIndex.2 2
hrStorageIndex.3 3
hrStorageIndex.4 4
hrStorageIndex.5 5
hrStorageIndex.6 6
hrStorageIndex.7 7
hrStorageIndex.101 101
hrStorageIndex.102 102
hrStorageIndex.103 103

No difference can be seen between the 2 outputs.
Do you have another idea, please ?

Try running:

Code: Select all

snmpwalk -O n -c public 36.125.1.12 .1.3.6.1.2.1.25.2.3.1.1

(notice the space between the -O and the 'n')

I have the same result :
snmpwalk -O n -c public 36.125.1.12 .1.3.6.1.2.1.25.2.3.1.1
hrStorageIndex.1 1
hrStorageIndex.2 2
hrStorageIndex.3 3
hrStorageIndex.4 4
hrStorageIndex.5 5
hrStorageIndex.6 6
hrStorageIndex.7 7
hrStorageIndex.101 101
hrStorageIndex.102 102
hrStorageIndex.103 103

Sorry for not noticing this earlier, but it looks like you are trying to gather disk information using the HOST MIB. Try adding the "SNMP - Get Mounted Partitions" data query to your host and see what happens. This data query is based on the host MIB and should work fine for this purpose.
