       The flushcached function connects to rrdcached, the RRD caching daemon, and issues a "flush" command for
       the given files. The daemon will put the files to the head of the update queue so they are written
       "soon". The status will be returned only after the files' pending updates have been written to disk.

       filename
               The name(s) of the RRD file(s) that are to be written to disk.

       --daemon|-daddress
               Address  of  the  rrdcached  daemon. If not specified, the RRDCACHED_ADDRESS environment variable
               must be set (see below).  For a list of accepted formats, see the  -l  option  in  the  rrdcached
               manual.

                rrdtool flushcached --daemon unix:/var/run/rrdcached.sock /var/lib/rrd/foo.rrd

       The following environment variables may be used to change the behavior of "rrdtool flushcached":

       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.
