Let's take a step back.
Fundamentally, there are two possible approaches to reporting information
via SNMP. Either the data must be munged into a form that matches the
MIB, or a MIB must be written that matches the format of the data.
The "simple script" extension mechanisms ("exec" and "extend") use the
first approach. We've defined a MIB structure that is flexible enough to
handle arbitrary script output. Which means that it can't make assumptions
about the format of this output, hence treating everything as text strings.
(That doesn't handle binary output very well, but never mind).
If you're needing to report multiple integer values, then you probably need
to take the second approach, and define and implement a suitable MIB for
your data. The simplest way to implement this would probably be using
the "pass" directive, which also invokes a shell-script - though this would
need to be tailored suitably.
The other possibility it to hack the code of the 'extend' module, and have it
report integer values rather than strings. That's not something we can do
globally, since it wouldn't be appropriate for many situations. But if this is
a private setup, then you can tweak things to your heart's content.
(That's the beauty of Open Source, after all!)
