In a distributed system, the hosts execute concurrently, generating asynchronous logs that are challenging to comprehend. We present two tools: ShiVector to transparently add vector timestamps to distributed system logs, and ShiViz to help developers understand distributed system logs by visualizing them as space-time diagrams. ShiVector is the first tool to offer automated vector timestamp instrumentation without modifying source code. The vector-timestamped logs capture partial ordering… CONTINUE READING
