rrdflushcached(1)
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.
