The name of the module isn't a lot of help.
What would be more useful would be to see the definitions
of these MIB objects - whether they are scalar objects
or part of a table.

It's not a matter of which one is correct - that depends
on what these MIB objects are meant to do.

"int_watch" is designed to implement a MIB object that
effectively tracks a given internal C variable.
When the agent receives a GET (or GETNEXT) request,
then it will return the current value of this C variable.
When it receives a SET request, it will update this variable.

Most of this is handled "internally" within the agent helpers,
so there's relatively little processing done in the generated
code itself.


"scalar" is a more general-purpose framework.
It will also return or update the value of some internal
variable, but the code for this is done in the generated
code framework.   So if you need to get the current value
from some underlying subsystem, or react to updates
in some way - then you can add the necessary code to
the handler routine.


If you need to do this additional processing, then use
the "scalar" template.   If you don't, then "int_watch"
should be fine.

Suck it and See.
