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.

            : an extensible agent, an SNMP library, tools for requesting or setting
            : information from SNMP agents, tools for generating and handling SNMP
            : traps and a version of the netstat command which uses SNMP. This
            : package contains the snmpd and snmptrapd daemons, documentation, etc.
            :
            : You will probably also want to install the net-snmp-utils package,
            : which contains NET-SNMP utilities.
