Hi,
I'm trying to use perl modules to communicate with rrdcached. My
intention is to update some rrd files.
The daemon is running fine, I can talk to iteratively by a socket:
# socat - /var/run/rrdcached.sock

I'm writing a program that updates rrd files automatically, and I want
this program to be able to communicate with the daemon.
So far, I've tried RRDs and RRD::Simple modules but none of them seem to
be able to update files *via daemon*.
I tried to do this:
RRDs::update ("$file", "--daemon unix:/var/run/rrdcached.sock",
"--template", "in:out", "N:$in:$out");
my $err = RRDs::error;
syslog('debug', "Update error: $err") if $err;
And in log file I get this error:
Jul 2 16:14:12 host nfsen[4663]: Update error: unknown option '--daemon
unix:/var/run/rrdcached.sock'
So, it does not behaves like the following commandline:
$ rrdtool update test.rrd --daemon unix:/var/run/rrdcached.sock N:12:13
As the `perldoc RRDs` page says :(
(commandline works fine)
Any ideas?
Thanks in advance,
Aramis.
