|
rrdflushcached - Flush the values for a specific RRD file from memory.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<rrdtool> B<flushcached>
|
|
S<[B<--daemon>|B<-d> I<address>]>
|
|
I<filename> [I<filename> ...]
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<flushcached> function connects to L<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.
|
|
|
|
=over 8
|
|
|
|
=item I<filename>
|
|
|
|
The name(s) of the B<RRD> file(s) that are to be written to disk.
|
|
|
|
=item B<--daemon>|B<-d> I<address>
|
|
|
|
Address of the L<rrdcached> daemon. If not specified, the
|
|
RRDCACHED_ADDRESS environment variable must be set (see below). For a
|
|
list of accepted formats, see the B<-l> option in the L<rrdcached>
|
|
manual.

=head1 ENVIRONMENT VARIABLES
|
|
|
|
The following environment variables may be used to change the behavior of
|
|
C<rrdtoolE<nbsp>flushcached>:
|
|
|
|
=over 4
|
|
|
|
=item B<RRDCACHED_ADDRESS>
|
|
|
|
If this environment variable is set it will have the same effect as specifying
|
|
the C<--daemon> option on the command line. If both are present, the command
|
|
line argument takes precedence.
