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!
