RRDLASTUPDATE(1)                               rrdtool                              RRDLASTUPDATE(1)

NAME
       rrdlastupdate - Return the most recent update to an RRD

SYNOPSIS
       rrdtool lastupdate filename [--daemon|-d address]

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

       filename
               The name of the RRD that contains the data.

       --daemon|-d address
               Address  of  the  rrdcached  daemon.  If  specified, a "flush" command is sent to the
               server before reading the RRD files. This allows rrdtool 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 option in the rrdcached manual.

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

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

       RRDCACHED_ADDRESS
           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.
