Efficient Interdomain Transmission of Performance Data - John Else, Citrix

Sign up or log in to save this to your schedule and see who's attending!

As users demand greater scalability from Citrix XenServer, the transmission of performance data from guests via xenstore is increasingly becoming a bottleneck. Future use of service domains is likely to make this problem worse. A simple, efficient way of transmitting time-varying datasets between userspace components in different domains is required. This talk will propose a lock-free mechanism to allow interdomain reporting of performance data without relying on continuous xenstore usage, and describe how it fits into the XAPI toolstack.
