Hello all,
I am learning how to add static trace points via trace_events.
I am seeing the trace using 'cat /sys/kernel/debug/tracing/trace' .
Naturally the tracing buffer size is limited. My question is, what is the
recommended way of reading trace data?
Ive looked at perf record/report, but so far, i have only managed to get
aggregated statistics, or complete dumps.
What i need is just a way to collect all the trace output to one file.
Basically i am using the trace events as a souped up printk (since i need
to collect large amounts of traces).
Do i need to use LTTng/viewer or something for this task?
Thanks!I've already found the solution to this, turns out there is trace_pipe as well. Sorry! -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.kernelnewbies.org/pipermail/kernelnewbies/attachments/20110820/da10d083/attachment.html
