RRDFLUSHCACHED(1)                    rrdtool                   RRDFLUSHCACHED(1)

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.

     filenameThe 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  RRD‐
             CACHED_ADDRESS environment variable must be set (see below).  For a
             list  of  accepted formats, see the -l option in the rrdcached man‐
             ual.

              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.
