US Patent 8478800 Log streaming facilities for computing applications

To facilitate log streaming in a computing cloud, application service providers may dynamically provision one or more named log streams. A file-oriented interface to log streams may be made available to a plurality of virtual computer system instances used to provide the application services. Application service providers may further dynamically provision one or more sets of log stream processing agents arranged in one or more log stream processing graphs. Particular log streams may be assigned to particular log stream processing graphs for real-time processing. Processed log streams and/or associated data may be stored for later inspection. Such provisioning and/or configuration may be performed with a unified Web-based interface.
