Abstract
Described herein are techniques to decompose a measurement of the latency experienced by a virtual machine into its additive components (e.g., host latency, kernel latency, network latency and storage latency). The host latency may be determined as the aggregate latency reported from the virtual disk of the virtual machine minus the aggregate latency reported from the datastore on which the virtual disk is stored. The network latency may be determined as the device latency reported from the datastore minus the storage latency reported by a storage system. Various sensor measurements (e.g., aggregate latency reported from the virtual disk and/or datastore) may be first pre-processed to compensate for non-idealities before being combined with other sensor measurements.
