<div>The current stable version of RRDTool only supports 'update' via rrdcached; if you're using TCP-based rrdcached this means there's no fallback to direct, either - what the rrdtool client does is to fall back to using direct, which can work OK if you've got UNIX sockets and the files are local, but is not good with TCP sockets.</div>
<div> </div>
<div>I've submitted some patches to Tobi to allow rrdcached to support 'last', 'first', and 'create' and 'info'. If you download the development snapshot you should get these.</div>
