NAME

       rrdlastupdate - Return the most recent update to an RRD

SYNOPSIS

       rrdtool lastupdate filename [--daemon|-d 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|-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 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.
