9 ``acrntrace`` is a tool running on the Service VM to capture trace data.
10 A ``scripts`` directory includes scripts to analyze the trace data.
18 The ``acrntrace`` tool runs on the Service VM to capture trace data and output
19 the data to a trace file under ``./acrntrace`` in raw (binary) data format.
25 -t max_time max time to capture trace data (in seconds)
26 -c clear the buffered old data (deprecated)
27 -r capture the buffered old data instead of clearing it
28 -a cpu-set only capture the trace data on the configured cpu-set
33 The ``acrntrace_format.py`` is an offline tool for parsing trace data (as output
54 outputs the data in decimal format. Alternatively, 'x' outputs the data in
55 hexadecimal format, and 'o' outputs the data in octal format.
58 counter (tsc), event ID (event), and the data logged in the trace file.

93 Here's a typical use of ``acrntrace`` to capture trace data from the Service VM,
94 convert the binary data to human-readable form, copy the processed trace
95 data to your development computer (Linux system), and run the analysis tool.
97 1. On the Service VM, start capturing buffered trace data:
113 #. Convert trace data to human-readable format:
119 Trace data will be converted to human-readable format based on a given format
122 #. Analysis of the collected trace data is done on your development computer.
123 Copy the collected trace data to your development computer via USB disk or
