I've added support for "PUTVAL" in sh/next now. I'm using the following
(a bit) dirty trick to tell apart "gauge" or "counter" values ("derive"
and "absolute" are handled exactly the same by lcc, so there's no point
in handling them differently in the client): any value containing a dot
is considered a "gauge" value, while everything else is a "counter".
Since lcc uses that information for formatting the values only, this is
a feasible approach imho. Another possible approach that came to my mind
would be to introduce a new data-type (in lcc) called something like
"automatic_t" which would be passed to lcc as a string and then passed
along to the daemon without further touching it. Personally, I like that
approach a bit better (after all, it's the daemon's job to handle types
and, in theory, it might use different type definitions anyway) but it's
more intrusive, so, I've used the other approach for now. Florian, if
you have any preferences on that, please tell me and I'll change the
code ;-)
