/meter

/log

That is on purpose, the log lets the client store any string It will not be indexed by elastic search and therefore not be addressable by other components like the SLA manager.

The meter message on the other hand is intended to be indexed and usable by other components. The DUE@VDC could for instance store the data utility values through that interface.

We will update the Readme to reflect that.
