Abstract: Various embodiments of a system and method for decentralized performance monitoring of host systems are described. Embodiments may include one or more client systems, each of which may monitor the performance of one or more host systems. In some embodiments, at least some of the host systems may be members of a cloud computing environment. A given client system may collect metrics from multiple different host systems and aggregate such metrics on the client system. In various embodiments, metrics may be collected by the client system directly from the multiple different host systems without utilizing a centralized repository of metrics. In various embodiments, the given client's receipt of the metrics from the multiple different hosts systems may be an initial aggregation of those metrics together on the same computer system. The client system may generate a graphical representation of the metrics collected from multiple hosts systems.
