| Thread-topic: | [Xen-API] Xen Management API draft |

However, I think it definitely should still use the xml-rpc interface, we just need to 'cook' the raw data into something more directly useful within xend so that there's no need to do high-rate polling on the API. This might involve using something like rrdtool to generate averages over different time scales etc. Ian _______________________________________________ xen-api mailing list xen-api@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/cgi-bin/mailman/listinfo/xen-api |
