USAGE
|
||
|
|
#####
|
||
|
|
Capture trace data on SOS
|
||
|
|
|
||
|
|
1) Launch acrntrace
|
||
|
|
Capture buffered trace data:
|
||
|
|
# acrntrace
|
||
|
|
or clear buffer before tracing start:
|
||
|
|
# acrntrace -c
|
||
|
|
Trace files are created under /tmp/acrntrace/, directory name with time
|
||
|
|
string eg: 20171115-101605
|
||
|
|
2) To stop acrntrace
|
||
|
|
# q <enter>
|
||
|
|
3) Copy the trace data to linux pc
|
||
|
|
# scp -r /tmp/acrntrace/20171115-101605/ xxx@10.239.142.239:/home/xxxx/t
|
||
|
|
race_data
|
||
|
|
|
||
|
|
Analyze the trace data on Linux PC
|
||
|
|
|
||
|
|
1) Run the python script to analyze the vm_exits:
|
||
|
|
# acrnalyze.py -i /home/xxxx/trace_data/20171115-101605/0 -o /home/xxxx/trac
|
||
|
|
e_data/20171115-101605/cpu0 --vm_exit
|
||
|
|
- "--vm_exit" specify the analysis to do, currently, only vm_exit analysis
|
||
|
|
is supported.
|
||
|
|
- A preprocess would be taken out to make the trace data start and end with
|
||
|
|
an VM_ENTER, and a copy of original data file is saved with suffix ".orig";
|
||
|
|
- Analysis report would be given on the std output and in a csv file with
|
||
|
|
name specified via "-o outpu_file";
|
||
|
|
