Abstract:
A server calculates correlations between complex event processing processes performed by virtual machines (VMs) so as to detect events from streams using condition expressions for identifying the events. The server obtains the load status of each of the VMs. The server then detects a VM having a processing load exceeding a predetermined level based on the load status thus obtained. When a VM having a processing load exceeding a predetermined level is detected, the server distributes the complex event processing processes to the respective VMs based on the calculated correlations between the complex event processing processes.
