Get method and value/regexp in snmp data query

Post by icewind »

Hi.

I wanna use SNMP data query for getting module statuses and their names in Cisco VSS. I use one OID to retrieve indexes and module statuses and completely different OID to get their names. The problem is the latter OID returns much larger list of names (it contains all desired modules and a lot of unnecessary ones). I tried to solve this problem by using get method in "method" field of XML template and it worked. But then the other problem occured. I'm using VALUE/REGEXP in "source" field to parse a string containing module name (I keep first 3 words). It worked while using walk method, but does not with get method. If I simply use value as a source, everything is fine except that modules' names are too long, so I guess something is wrong with combining get method and VALUE/REGEXP.

Any ideas? :) Can the first problem (having too many indexes for OID returning names) be solved with walk method?

My template:

Code: Select all

<?xml version="1.0"?>

<interface>

        </VSSmodule_statusIN>

        <VSSmodule_status>
            <name>Module status</name>

        </VSSmodule_status>
      
    </fields>

This is what I get with verbosing the query if using walk method (it queries also unnecessary indexes for module name):

Were you able to solve this issue? I have a similar:
