A method and system for detection of completeness of tracing data describing globally distributed, synchronous and asynchronous transaction in real time is presented. Monitored transactions may be executed on different computers systems, connected via computer networks with different and fluctuating latencies, and timing systems of the computers systems may be subject to different time drifts. The system and method may be implemented by different, multiple collector nodes responsible for collecting and forwarding transaction tracing data to a monitoring node, responsible for correlating transaction tracing data. Collector nodes and monitoring node may reside on different computer systems, which may be connected via computer networks with different and fluctuating latencies, and timing systems of the computers systems may be subject to different time drifts. Completeness detection may consider different time drifts and different, fluctuating network latencies of all involved computer system and computer networks to translate time information received with tracing data into a virtual timing system, which may be used to implement a deterministic algorithm to detect completeness of tracing data describing the execution of distributed, synchronous and asynchronous transactions.
