Confluo: Distributed Monitoring and Diagnosis Stack for High-speed Networks

• Confluo: end-host stack that can be integrated with existing network management tools to enable monitoring and diagnosis of network-wide events using telemetry data distributed across end-hosts, even for high-speed networks

• Atomic MultiLog: support highly-concurrent read-write operations by exploiting two properties specific to telemetry data

  • once processed by the stack, the data is neither updated nor deleted

  • each field in the data has a fixed pre-defined size
