They could certainly make use of it. Currently I have only implemented the
"create", "update", "tune" and "graphv" commands, but the basic
infrastructure for all other commands is there. I have also implemented a
simple pooling service, so this is actually multi-threading capable for
EVERY implemented rrdtool command [and not just for those with explicit
support in librrd_th] and a maximum-request count per client to avoid any
negative effects of a long running rrdtool (eg. leaks of any kind). It
also uses an internal form of "transaction" which allows for the use of
the "mkdir", "cd" and "ls" commands.
I have actually implemented this for a very long running personal project
of mine - a documentation system for networks that can also do a lot of
(distributed!) monitoring (including Nagios configuration support, NRPE
deployment and RRD graphing). This was partly because I really didn't like
OpenNMS (sorry guys!). But I think that a common Java based RRD interface
is something our little segment of the world misses quite badly.
I also want to say, that the pipe interface seems to be THE (most) correct
interface for rrdtool integration in every language. Many, many thanks for
this interface. If only I would have realized this earlier! OTOH, there
might be some improvements for this interface as well... But before I
submit anything, first let's see how this iteration of Java RRD support
