Managing traces to capture data for memory regions in a memory

摘要

Provided are a computer program product, system, and method for managing traces to capture data for memory regions in a memory. A trace includes a monitor parameter used by a trace procedure to monitor data in a memory device. A frequency is determined at which the trace procedure monitors the memory device. The trace procedure is invoked at the determined frequency to perform trace procedure operations comprising determining a region in the memory device according to the monitor parameter and copying data in the determined region to trace data in a data space.

1. A computer program for capturing data stored in a memory device, the computer program product comprising a computer readable storage medium having computer readable program code embodied therein that executes to perform operations, the operations comprising:
receiving settings for a plurality of traces each including a monitor parameter used by a trace procedure to monitor data in the memory device; and for each of the traces, performing:
determining a frequency at which the trace procedure monitors the memory device based on at least one of processor resources devoted to the traces and a size of a memory area of the memory device monitored by the traces; andinvoking a trace procedure at the determined frequency to perform trace procedure operations comprising:
determining a region in the memory device according to the monitor parameter; andcopying data in the determined region to trace data in a data space.
