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

       rrdtool last filename [--daemon address]

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

	       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 last --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

       The following environment variables may be used to change the behavior of "rrdtool last":

	   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.
