RRDLASTUPDATE(1)						      rrdtool							  RRDLASTUPDATE(1)

NAME
       rrdlastupdate - Return the most recent update to an RRD

SYNOPSIS
       rrdtool lastupdate filename [--daemon 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 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

	   present, the command line argument takes precedence.
