NNNNAAAAMMMMEEEE
     rrdtool info - extract header information from an rrd

DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN
     The iiiinnnnffffoooo function prints the header information from an rrd
     in a parsing friendly format.

     Check the rrdcreate manpage if you are uncertain about the
     meaning of the individual keys.

EEEEXXXXAAAAMMMMPPPPLLLLEEEE
     This is the output generated by running iiiinnnnffffoooo on a simple rrd
     which contains two datasources and one rra. Note that the
     number after the _l_a_s_t___u_p_d_a_t_e keyword is in seconds since
     1970. The string NNNNaaaaNNNN stands for _*_U_N_K_N_O_W_N_* data. In the
     example it means that this rrd has neither minimum not
     maximum values defined for either of its datasources.
