Snmp Data Query for multiple values

Post by jfarese »

I would like to create a data query for cisco switches that identifies free and used memory. The appropiate oid for this table is below.

snmpwalk -v 2c -c xxxx x.x.x.x 1.3.6.1.4.1.9.9.48
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.1 = STRING: "Processor"
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.2 = STRING: "I/O"
SNMPv2-SMI::enterprises.9.9.48.1.1.1.3.1 = INTEGER: 2
SNMPv2-SMI::enterprises.9.9.48.1.1.1.3.2 = INTEGER: 0
SNMPv2-SMI::enterprises.9.9.48.1.1.1.4.1 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.48.1.1.1.4.2 = INTEGER: 1
SNMPv2-SMI::enterprises.9.9.48.1.1.1.5.1 = Gauge32: 3446124
SNMPv2-SMI::enterprises.9.9.48.1.1.1.5.2 = Gauge32: 746148
SNMPv2-SMI::enterprises.9.9.48.1.1.1.6.1 = Gauge32: 1509044
SNMPv2-SMI::enterprises.9.9.48.1.1.1.6.2 = Gauge32: 2075772
SNMPv2-SMI::enterprises.9.9.48.1.1.1.7.1 = Gauge32: 1477864
SNMPv2-SMI::enterprises.9.9.48.1.1.1.7.2 = Gauge32: 2067540

There are 2 pools Processor and I/O

free memory
SNMPv2-SMI::enterprises.9.9.48.1.1.1.6.1 = Gauge32: 1509044 Processor
SNMPv2-SMI::enterprises.9.9.48.1.1.1.6.2 = Gauge32: 2075772 I/0


used memory

SNMPv2-SMI::enterprises.9.9.48.1.1.1.5.1 = Gauge32:3446124 Processor

SNMPv2-SMI::enterprises.9.9.48.1.1.1.5.2 = Gauge32: 746148 I/0

What is the proper way create the query. I do not think I can create an indexed query, and I would like not to create something with individual oids.

Thanks,

Even if there would be only a single row in the table, an indexed snmp data query would do. See 1st link of my sig, Advanced stuff

I apologize in advance

Gandalf,
I have read the info in your link but I am having trouble understanding.


I am want to use
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.1 = STRING: "Processor"
SNMPv2-SMI::enterprises.9.9.48.1.1.1.2.2 = STRING: "I/O"

to build the index and use the trailing .1 and .2 in the rest of the oids to build the table. I know I am missing something here but I don't know what it is. I am attaching my xml and a verbose query.

Thanks

figured it out by accident

Ok, I guess I figured it out by accident

I needed to use an oid_index_parse for the last number in the oid
as well as not put an oid for the index under fields.

<fields>
<Index>
<name>Index</name>
<method>walk</method>
<source>index</source>
<direction>input</direction>
</Index>


I thought it was required to have an oid index but I was wrong.

understanding the xml sytax can be difficult to get your head around I appreciate the help
