rrdflushcached

Name
     rrdflushcached - Flush the values for a specific RRD file
     from memory.

Synopsis
     rrdtool flushcached [--daemon|-d address] filename [filename
     ...]

Description
     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|-d address
             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

Environment Variables
     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.
