Reading debug/tracing info

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!
