rrdtool-1.4.7
    
    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.
