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.
