       The llaasstt function returns the UNIX timestamp of the most recent update
       of the RRD.

       _f_i_l_e_n_a_m_e
               The name of the RRRRDD that contains the data.

       ----ddaaeemmoonn _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 rrrrddttooooll 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 --ll option in the rrdcached manual.

                rrdtool last --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

       ----nnoofflluusshh
               If the rrdcached daemon is being used, then omit the flush
               normally send before returning the last update.  If you add
               this option, you get the last time the file on disk was
               updated; if you have relatively low cache times and are calling
               this frequently it will preserve the caching benefit

       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.
