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.
