     The tune option allows you to alter some of the basic
     configuration values stored in the header area of a Round
     Robin Database (RRRRRRRRDDDD).  All these tunable parameters together
     decide when data fed into an RRRRRRRRDDDD is to be regarded as
     invalid. Invalid data is entered into the database as
     *UNKNOWN*.

     The main application of the ttttuuuunnnneeee function is to relax the
     validation rules on an RRRRRRRRDDDD. This allows to fill a new RRRRRRRRDDDD
     with data available in larger intervals than what you would
     normally want to permit.

     _f_i_l_e_n_a_m_e
             The name of the RRRRRRRRDDDD you want to tune.

             modify the _h_e_a_r_t_b_e_a_t of a data source. By setting
             this to a high value the rrd will accept things like

rrdtool                                                RRDTUNE(1)



     Set the minimum required heartbeat for data sources 'in',
     'out' and 'through' to 10000 seconds which is a little over
     one day in data.rrd.  This would allow to feed old data from
     mrtg-2.0 right into rrdtool without generating *UNKNOWN*
     entries.
