<div class="moz-cite-prefix">I have implemented this. And yes, it
might be useful. I might support it in my java interface to rrd.<br>

My implementation can be found in branch pipe-restore in my repo

Note that I haven't rebased/merged the stuff into master. If I

<div>I don't think it does. Why isn't a usual file good
enough? You can store it in tmpfs if the i/o speed is the
concern. But usually rrdtool is slower than disk i/o anyway.<br>
<br>
What I typically do, is execute rrdtool dump from an SSH
command, so that its remote stdout is the ssh's local
stdout, and save the XML to a local temporary file. Next the
local rrdtool restore would slurp that file. <br>
<br>
If you need the XML to tweak some RRD parameter, you can use
RRD::Tweak Perl module instead.<br>

Question: rrdtool pipe interface - restore support?<br>
</div>
<div class="y_msg_container"><br>
Hi,<br>
<br>
Does the rrdtool pipe interface somehow support an
in-stream xml restore<br>
command?<br>
<br>
"dump" is (mostly) working as expected, although one
has to look for<br>
the "OK" response line to find out where the xml ends,
but this is not a<br>
problem. "restore" however has the problem that it
does not take input<br>
over the pipe interface. Using "-" as XML input seems
to *partly* work,<br>
but fails with a parser error. Using /dev/stdin works
when using the<br>
pipe interface on the command line, but can't work
when using the pipe<br>
over a TCP connection....<br>
<br>
Any ideas?<br>
<br>
I admit that I am using a rather old version: 1.4.7...<br>
<br>
