[Devmon] create new template question

[Jon D. <jd...@us...>]

Greetings -

I am trying to develop a new template for Cisco Wireless Controllers, and running into a snag with devmon's features. Here is a quick snippet of the SNMP conversations I am trying to analyze:

(names of wireless access points connected to controller)
snmpwalk -v2c -cpublic 10.13.1.4 .1.3.6.1.4.1.14179.2.2.1.1.3
SNMPv2-SMI::enterprises.14179.2.2.1.1.3.0.35.235.10.79.64 = STRING: "wap-1st-2"
SNMPv2-SMI::enterprises.14179.2.2.1.1.3.0.37.132.253.194.144 = STRING: "wap-2nd-5"
SNMPv2-SMI::enterprises.14179.2.2.1.1.3.0.37.132.253.200.192 = STRING: "wap-2nd-4"

(number of clients connected to each WAP - by radio)
snmpwalk -v2c -cpublic 10.13.1.4 .1.3.6.1.4.1.14179.2.2.2.1.15
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.35.235.10.79.64.0 = Counter32: 4
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.35.235.10.79.64.1 = Counter32: 1
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.37.132.253.194.144.0 = Counter32: 7
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.37.132.253.194.144.1 = Counter32: 3
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.37.132.253.200.192.0 = Counter32: 1
SNMPv2-SMI::enterprises.14179.2.2.2.1.15.0.37.132.253.200.192.1 = Counter32: 1

In the above examples, 0.35.235.10.79.64 represents a single WAP (the repeater part of the oid identifies the MAC address in decimal). In the above example, the WAP labeled as wap-1st-2 has a "repeater OID" of 0.35.235.10.79.64.0, which corresponds to a MAC address of 00:23:eb:0a:4f:40 (not particularly germane to this question, but I thought I would include the example).

Each WAP has two radios, which lead to two different results (.0 and .1).

What I would *like* to have is a nice devmon table similar to "regular" switches, with the WAP name in the 1st column, the .0 client count in column 2, and .1 count in column 3:

WAP Name	2.4GHz clients	5 GHz clients
wap-1st-2	4		1
wap-2nd-5	7		3
wap-2nd-4	1		1

But I believe I have found a limitation with the devmon template capabilities. I can easily get the names of the WAPs, and even the repeater section of the OID (via a transform of INDEX). But I have tried the CHAIN, INDEX, and REGSUB transform, and nothing is able to produce the results I seek. 

I need to have a "devmon transforms" that can give me a new oid like follows:

wapClients24  = {.1.3.6.1.4.1.14179.2.2.2.1.15.}{wapRepeaterOid}.0
wapClients24  = {.1.3.6.1.4.1.14179.2.2.2.1.15.}{wapRepeaterOid}.1

In all my reading of the devmon documentation, I cannot think of any scheme to do this type of operation.

Please accept my apologies for such a verbose post, I hope the details might help you understand my situation. Any help would be appreciated.
