Description: RRD is the Acronym for Round Robin Database. RRD is a system to store and
: display time-series data (i.e. network bandwidth, machine-room temperature,
: server load average). It stores the data in a very compact way that will not
: expand over time, and it presents useful graphs by processing the data to
: enforce a certain data density. It can be used either via simple wrapper
: scripts (from shell or Perl) or via frontends that poll network devices and
: put a friendly user interface on it.

パッケージのバージョンを調べると意外と新しかったので、tarball からインストールはやめて yum で

$ sudo yum install -y rrdtool
