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.

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.
