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.
