Sorry if this seems rudimentary - but i'm looking into this stuff for the first time and i'm finding it a bit confusing.
I downloaded and i'm using filer-mrtg which uses mrtg to plot various system parameters - some of which are collected using SMTP.
In the cfg files for the filers i can see lines like this:
Target[ast-h-tsb02.net.snmp]: 1.3.6.1.4.1.789.1.2.2.2.0&1.3.6.1.4.1.789.1.2.2.3.0:public@ast-h-tsb02
The one above gets total network traffic from the filer.
Where do these long lines of numbers come from? Where are they defined? I'm getting the impression that they are somehow related to the netapp.mib file - but i can't find any clues how that format is converted into these sets on numbers.
For instance, i'd like to monitor snapshot size - it looks like i could do it according to the netapp.mib but i cannot figure out what string of numbers or parameters to put into the Target field.
Any tips - or pointers (including "go read this book") would be much appreciated.
Thx, Graham
