The whole <Plugin rddtool> block was commented out in collectd.conf. I installed cgp, and configured collectd.conf rrdtool : <Plugin rrdtool> # DataDir "/usr/var/lib/collectd/rrd" DataDir "/var/lib/collectd/rrd" CacheTimeout 120 CacheFlush 900 </Plugin> The initial load, at this point, brings up blank images and generates a lot of warnings in the weblog. 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. However I now have some pretty graphs. I'm going to notch this up as a success for now, thanks! My next problem is that my nginx stats are not showing up. I have this in my collectd.conf: LoadPlugin nginx <Plugin nginx> URL "http://www.mysite.com/nginxstub?auto" </PLugin> The rrd files are being produced: > ls -1 /var/lib/collectd/rrd/www.mysite.com/nginx nginx_connections-active.rrd nginx_connections-reading.rrd nginx_connections-waiting.rrd nginx_connections-writing.rrd nginx_requests.rrd However cgp's hosts.php displays a little image stating that the plugin is not loaded. Is this a cgp plugin, a configuration issues, or something else?
