rrdlast

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.
