<p class=MsoNormal>I have patched the current RRDTool trunk sources (rrdtool-1.4.99910091600)
to allow the rrdcached to work with a few more commands, with a view to
improving MRTG support for rrdcached.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>You can download the combined diff from <a
href="ftp://ftp.auckland.ac.nz/pub/tmp/rrd-changes.dif">ftp://ftp.auckland.ac.nz/pub/tmp/rrd-changes.dif</a>
if you’re interested.<o:p></o:p></p>
<p class=MsoNormal>I am still testing these prior to officially submitting them
to Tobi but would appreciate any feedback from the rrd-developers community.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>These patches do the following:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Add INFO <filename>, FIRST <filename>
<index>, LAST <filename> and CREATE <rrdfile> [-b start][-s
step][-O] <DSdefs> <RRAdefs> to the rrdcached functions.<o:p></o:p></p>
<p class=MsoNormal>Add rrd_create_set_no_overwrite as a function in
rrd_create.c to allow the overwrite flag to be set externally<o:p></o:p></p>
<p class=MsoNormal>Add rrdc_info, rrdc_first, rrdc_last, rrdc_create functions
in rrd_client.c<o:p></o:p></p>
<p class=MsoNormal>Add rrdcached support to rrd_info(), rrd_first(), rrd_last()
and rrd_create()<o:p></o:p></p>
<p class=MsoNormal>Add --noflush (-F) option to rrd_info(), rrd_last() to
prevent cache flushing before function call if required for efficiency<o:p></o:p></p>
<p class=MsoNormal>Add --daemon option to rrd_info(), rrd_first() for rrdcached
support<o:p></o:p></p>
<p class=MsoNormal>Add buffer_add_ulong function to rrd_client.c (used by new
rrdc_* functions)<o:p></o:p></p>
<p class=MsoNormal>All relevant documentation updated<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Might try to add rrd_tune as well before submitting if all
goes well (this will HAVE to flush the data first I think) but now I’m
off for a long weekend until Monday!<o:p></o:p></p>
