Did you specify another dir in your collectd.conf (DataDir in the<br>
rrdtool plugin section) ?<br>
<br>
Also, you may take a look at cgp[1], a web based front-end to collectd<br>

That's because there isn't any data in RRDs (having just moved collectd's logging point/dir). That might be confusing/worrying for a noob. I don't know if you can build in a check for that, just as some re-assuring feedback to the user.</div>
