RRDLAST(1)			     rrdtool			      RRDLAST(1)

NAME
     rrdlast - Return the date of the last data sample in an RRD

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

DESCRIPTION
     The  last	function returns the UNIX timestamp of the most recent update of
     the RRD.

     filenameThe 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  rrd-
	     tool 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 last --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 last":

     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.
