I am trying to start a service with the stack trace option on and pipe that output into a splunk port. It does not seem to be capturing any data.
I place this command on the etc/init.d start script
su - $user -c "/usr/bin/strace -f -ttt -e trace=all $LOCAL_PATH/myprocess.pl start | /usr/bin/nc my.splunk.com 9050"
Check that your ports are open and that splunk is listening for traffic on 9050. You can see an example described here for Splunk Storm (and Splunk Enterprise) http://docs.splunk.com/Documentation/Storm/Storm/User/Howtoforwarddatavianetcat
