140
.IX Header "DESCRIPTION"
141
The \fBflushcached\fR function connects to rrdcached, the \s-1RRD\s0 caching daemon,
142
and issues a \*(L"flush\*(R" command for the given files. The daemon will put the
143
files to the head of the update queue so they are written \*(L"soon\*(R". The
144
status will be returned only after the files' pending updates have been
146
.IP "\fIfilename\fR" 8
148
The name(s) of the \fB\s-1RRD\s0\fR file(s) that are to be written to disk.
149
.IP "\fB\-\-daemon\fR \fIaddress\fR" 8
150
.IX Item "--daemon address"
151
Address of the rrdcached daemon. If not specified, the
152
\&\s-1RRDCACHED_ADDRESS\s0 environment variable must be set (see below). For a
153
list of accepted formats, see the \fB\-l\fR option in the rrdcached

.IX Header "ENVIRONMENT VARIABLES"
161
The following environment variables may be used to change the behavior of
162
\&\f(CW\*(C`rrdtool\ flushcached\*(C'\fR:
163
.IP "\fB\s-1RRDCACHED_ADDRESS\s0\fR" 4
164
.IX Item "RRDCACHED_ADDRESS"
165
If this environment variable is set it will have the same effect as specifying
166
the \f(CW\*(C`\-\-daemon\*(C'\fR option on the command line. If both are present, the command
167
line argument takes precedence.
