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.

       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 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.
