DDEESSCCRRIIPPTTIIOONN
       The llaassttuuppddaattee function returns the UNIX timestamp and the value stored
       for each datum in the most recent update of an RRD.

       _f_i_l_e_n_a_m_e
               The name of the RRRRDD that contains the data.

       ----ddaaeemmoonn|--dd _a_d_d_r_e_s_s
               Address of the rrdcached daemon. If specified, a "flush"
               command is sent to the server before reading the RRD files.
               This allows rrrrddttooooll to return fresh data even if the daemon is
               configured to cache values for a long time.  For a list of
               accepted formats, see the --ll option in the rrdcached manual.

       The following environment variables may be used to change the behavior
       of "rrdtool lastupdate":

       RRRRDDCCAACCHHEEDD__AADDDDRREESSSS
           If this environment variable is set it will have the same effect as
           specifying the "--daemon" option on the command line. If both are
           present, the command line argument takes precedence.
