Riemann is an event server that allows for fairly advanced aggregation and routing of events and can form part of such a solution. Suro is Netflix’s data pipeline and operates in a similar space. Suro is explicitly used to handle both metrics associated with user behavior, and more operational data like application logs. This data can then be dispatched to a variety of systems, like Storm for real-time analysis, Hadoop for offline batch processing, or Kibana for log analysis.
