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.
