Sorry for the delay in responding.
This is an interesting problem.

It turns out that the cause is a combination of a minor "error" in
your monitor line, and/or insufficienty robust checking in the code
that implements this functionality.

The "monitor" line is primarily intended for watching a *group* of MIB
instances, and triggering a trap whenever any one of them triggers the
specified test.   So one option would be to use a config directive
such as:

    monitor -u pippo -r 3 mymon nsExtendResult != 0

If you specifically want to monitor this one single instance, then
there's a flag to indicate this:

    monitor -I -u pippo -r 3 mymon nsExtendResult.\"mytest\" != 0

Either of these lines should work properly.

The problem here was that the agent was working with the results of
GETNEXT nsExtendResult.\"mytest\"  - which refers to a completely
different object altogether.
This is something that needs to be fixed.

But the suggestions above should provide a workaround in the meantime.
