Question #99926 on Graphite changed:

    Status: Open => Answered

chrismd proposed the following answer:
Yes you can move wsp files around all you want. Since you want to change
their retention schema at the same time what you should actually do is
resize the files first (using the whisper-resize.py script under
whisper/bin/ in trunk), then move them.

As for sending events when new metrics are created, that is an
*excellent* idea. Carbon now supports AMQP for receiving data and I
think it would also serve as a very natural mechanism for events like
this. Unfortunately the only "event-driven" way to do this now would be
to tail the storage/log/carbon-cache/creates.log file.
