     The  llaasstt  function returns the UNIX timestamp of the most recent update of
     the RRD.

     _f_i_l_e_n_a_m_eThe 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  rrrrdd‐‐
             ttooooll 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 last":

         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.
