<p class="MsoNormal">I'm trying to get the 500 directories (one for each host under the graphite root ) into one directory. Replace doesn't look to be doing that. I posted a screen shot of what I am looking at now, it's cropped but if i could get all of
these sorted under a sub dir it would beat digging through the whole list to find what I want<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Collectd will send to carbon->whisper->graphite-web. You will want to replace the values before sending off to carbon.<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Replace does work, but again, it depends on what name structure you have now and what you want it to be. The screenshot only shows the top level directory, i.e. the hostnames. It would be helpful to see the
subdirectories under a hostname.<o:p></o:p></p>

<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">The target_replace examples are scarce. I have a simple setup using the CPU and Interface plugin, with the CSV plugin for output to a local directory.<o:p></o:p></p>
