A monitoring system uses existing tracing data describing individual distributed transactions to determine if a recorded thread communication performed by the monitored transactions is internal to a monitored application or whether the recorded thread communication is an outgoing communication. Thread communications which are sent and received by threads that are monitored by the monitoring system are considered to be internal communications. Thread communications for which only the sending thread is monitored are considered to be outgoing communications. The determination process analyzes client side tracing data of the recorded thread communication and determines whether corresponding server side tracing data is available. If no corresponding server side tracing data is available, the thread communication is considered to be an outgoing communications. Examples of thread communications include HTTP requests, web service calls, and remote method invocations.

Method and system for tracing individual transactions at the granularity level of method calls throughout distributed heterogeneous applications without source code modifications including the detection of outgoing requests

Methods and systems for out-of-application bytecode instrumentation and performance monitoring of applications, such as globally-distributed applications, decouple (1) acquiring measurements through sensor execution at applications; (2) instrumenting application bytecode with sensor bytecode and buffering and sending measurements at collector nodes; and (3) controlling instrumentation and correlating measurements at a central monitoring node. Collector nodes and applications may employ secured, high bandwidth network connections (e.g., a typical LAN connection). Collector nodes and the central monitoring node may employ non-secured, lower-bandwidth network connections (e.g., a typical WAN connection) and may use encryption and/or compression without burdening the monitored application. Multiple parallel instrumentation engines in collector nodes eliminate the possible instrumentation bottleneck presented by one centralized instrumentation engine in a single server. Moreover, decentralized buffering of monitoring event data allows management of peak measurement loads on the monitoring node.

Methods and system for global real-time transaction tracing

The present invention provides a method and system for tracing and monitoring of distributed transactions spanning multiple threads or processes, running on multiple host systems, connected by a computer network. The correlation of distributed transactions is based on information that uniquely may identify execution paths within a virtual machine, additional to information which uniquely may identify the virtual machine that processes the execution path. The correlation information is transferred from a monitored thread to threads that are activated by the monitored thread and allows to reconstruct parent-child relations between different threads. Participating threads may run in different processes, in different virtual machines or on different host systems.
