snmp query issue

Post by colson »

I'm trying to create a query to monitor my UPS. I'd like to know what the oid_index should be for the following OIDs:

.1.3.6.1.4.1.13891.101.1.1.0 = STRING: "Mitsubishi"

I'm not getting the data that I want. THe verbose query returns:

+ Running data query [17].
+ Found type = '3' [snmp query].
+ Found data query XML file at 'C:/cacti-0.8.7d/resource/snmp_queries/ups.xml'

and if I try to change the walk to .1.3.6.1.4.1.13891.101 (to get a broader walk) I get:

Notice: Undefined offset: 71 in C:\cacti-0.8.7d\lib\data_query.php on line 243

Notice: Undefined offset: 71 in C:\cacti-0.8.7d\lib\data_query.php on line 262

How do I expand my query to get the OIDs I need further along the tree?

Thanks in advance.

Having the MIB for that device would be useful to resolve the OID to their names. read the snmp xml template guide in http://docs.cacti.net/

I've attached the MIB.

Thanks again for the assistance.

Great, so now use that mib file with that snmpwalk you posted so the OIDs are resolved to their textual names.

When you create your snmp xml file, you might want to read http://docs.cacti.net/howto:data_query_ ... _templates too.

Looks like .1.3.6.1.4.1.13891.101.3.2.0 might be the index count.

Yea, what you were doing before would not work at all. It was not indexable data. Another good method is to walk the entire enterprise MIB using textual descriptions. When you remove the numeric and add the parsing from the MIB file, it will all start to make sense.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?

It's slowly making sense, but I'm still unclear why .1.3.6.1.4.1.13891.101.3.2.0 would be the oid_index.

What in particular are you looking to monitor? It seems to me there are multiple "indexes" in the walk you provided.

I want to monitor the following:
<upsInputVoltage>
<name>Input Voltage</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.13891.101.3.3.1.3.1</oid>
</upsInputVoltage>
<upsOutputVoltage>
<name>Output Voltage</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.13891.101.4.4.1.2.1</oid>
</upsOutputVoltage>
<upsOutputPower>
<name>Output Power</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.13891.101.4.4.1.4.1</oid>
</upsOutputPower>
<upsOutputPercentLoad>
<name>Output Percentage Load</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.13891.101.4.4.1.5.1</oid>
</upsOutputPercentLoad>
<upsIdentManufacturer>
<name>Manufacturer</name>
<method>walk</method>
<source>value</source>
<direction>output</direction>
<oid>.1.3.6.1.4.1.13891.101.1.1.0</oid>

But that said, I can't figure out what the correct index should be.

I'm no expert by any stretch of the word, but I think you are browsing three different indexes - 101.1, 101.3 and 101.4.

I don't know if it will work, but you can try .1.3.6.1.4.1.13891.101 as your index.
Thanks,

Also, if I do the walk using the textual descriptions in the mib using the following index:

<oid_index>UPS-MIB::Tag</oid_index>

can I still run an OID/REGEX on the OID number or am I only able to parse text at this point?


Must.....unwind......brain......tangled.....knot.....

Thanks for the help!

[personal opinion]I would prefer using ASN.1 numerical OIDs. They are more reliable than textual representation[/personal opinion] I indeed never tried REGEXP on textual representation
