You need to create a custom stanza for this new Target.


You can do this manually, or (if you will need to do this same thing
frequently) you can create a custom host template for cfgmaker and use it
with the ¨Chost-template option.


The new stanza should define the Target in a similar way to this:


CnTWaLK1. at device


Note that 

(a)    you MUST have two items in a Target, separated by ¡®&¡¯

(b)   we¡¯re using pseudoZero for the second as we¡¯re only interested in
one and don¡¯t want to count again

(c)    we¡¯re using the CnTWaLK prefix to walk the tree and count the items
(see the MRTG documentation)

(d)   You¡¯ll likely need to have Options[users]:gauge,noo  to make this

(e)   Set your appropriate community string, device identifier, and a suffix
of :::::2 if you use SNMPv2

(f)     If you want to make a custom host template, you¡¯ll need to know
Perl.  See http://www.steveshipway.org/cfgmaker for a few examples.

Subject: [mrtg] using smnp?


Im well versed in using MRTG to graph our network interfaces, but Im less
sure on the best way to use SNMP based queries?

I have an SNMP string (. which will give
me the number of users per radio per Access Point  which Id like to turn
into a series of Graphs> If I walk the MiB, that query will return 590

Normally Id point cfgmaker at the router or switch, but Im unsure how to get
a config file for this query that I can then edit?


If someone can give me a pointer Id be very grateful
