A method, a computer program product, and a computer system for integrating social media and infrastructure monitoring of a service provider. The method, the computer program product, and the computer system include mapping a service provided by the service provider to components of an infrastructure of the service provider, requesting a social media service to conduct a search of consumer feedback regarding the service, receiving information of the search from the social media service, evaluating the service through analyzing the information of the search, receiving status information of the infrastructure from a monitoring system of the service provider, correlating a result of evaluating the service to the status information of the infrastructure, and providing the service provider with visualization of the result that is correlated to the infrastructure.

Throughput of a high-volume throughput-centric computer system is controlled by dynamically adjusting a concurrency level of a plurality of events being processed in a computer system to meet a predetermined target for utilization of one or more resources of a computer system. The predetermined target is less than 100% utilization of said one or more resources. The adjusted concurrency level is validated using one or more queuing models to check that said predetermined target is being met. Parameters are configured for adjusting the concurrency level. The parameters are configured so that said one or more resources are shared with one or more external programs. A statistical algorithm is established that minimizes total number of samples collected. The samples may be used to measure performance used to further dynamically adjust the concurrency level. A dynamic thread sleeping method is designed to handle systems that need only a very small number of threads to saturate bottleneck resources and hence are sensitive to concurrency level changes.
