Monitoring dynamic quality of service based on changing user context

One embodiment provides a method for monitoring context-dependent quality of service in a shared computing environment that includes detecting, by a processor, a change in context. Context includes user context and external context, and user context comprises physical activity, mood, engagement levels and type of events. Prior assigned service classes are updated to updated service classes based on the change in context. Service level agreement (SLA) statistics for each assigned service class are aggregated and collected. Each assigned service class includes at least one SLA based on aggregate services received by individual users in that assigned service class, and aggregating SLA statistics is based on a statistical function.
