An apparatus, system, and method are provided for gathering trace data indicative of resource activity on a computer system. The present invention includes a monitoring module that initiates one or more activity monitors on a target computer system to detect different types of resource activity. A determination module determines activity indicators involving resources of the target computer system using the one or more activity monitors. The activity indicators may comprise a variety of information useful in identifying one or more separate resource activities. A collection module organizes the activity indicators into trace data representative of the resource activity. Preferably, the monitoring module, determination module, and collection module operate continuously on the target computer system. In this manner, the trace data includes an accurate set of both current activity indicators as well as historical activity indicators.
