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

SYNOPSIS
       rrdtool last filename [--daemon address]

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