rrdd runs in the dom0 of a Xen host, and periodically collects numerical
performance data. This data is archived to disk in the
RRD format, and can be
retrieved over HTTP.
rrdd also implements a plugin mechanism, by which other processes can
register additional datasources to be collected.
The easiest way to install is via opam:
opam switch create new-env
opam repo remove default
opam repo add xs-opam https://github.com/xapi-project/xs-opam.git
opam install xcp-rrdd
