OLIC: OnLine Information Compression for Scalable Hosting Infrastructure Monitoring
Quality-Of-Service (QoS) management often requires a continuous monitoring service to provide updated information about different hosts and network links in the managed system. However, it is a challenging task to achieve both scalability and precision for monitoring various intra-node and inter-node metrics (e.g., CPU, memory, disk and network delay) in a large-scale hosting infrastructure. In this paper, the authors present a novel OnLine Information Compression (OLIC) system to achieve scalable fine-grained hosting infrastructure monitoring. OLIC models continuous snapshots of a hosting infrastructure as a sequence of images and performs online monitoring data compression to significantly reduce the monitoring cost.
