Hi Mathi, I attach two pictures from the output of:
$./trace2dot -t osafamfd -f saClmDispatch -d amfd_trace.dot $ dotty amfd_trace.dot and $./trace2dot -t osafamfd -d amfd_trace.dot $ dotty amfd_trace.dot /Thanks HansN On 09/10/2015 10:59 AM, Mathivanan Naickan Palanivelu wrote:
Hi Hans, I do appreciate the idea of suggesting dotty, good thought! I did run dotty as mentioned in the patch. We could place the trace2dot with 'execute' permissions and place it under tools/devel/dot directory. Also, the output i get after running dotty doesn't looks intuitive to me. So, for comparison sakes,could you send a picture (snapshot) of how the graph looks to you when you run it on osafamfd trace file?
