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

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.
