Event Tracing in the Linux kernel

[David Kahurani]

Hello,

I have compiled a pretty recent Linux kernel mostly basing the
configuration on the older kernel.

I am now testing out the event tracing system but seem to be having a
problem.

Having enabled all events with

# echo *:* > /sys/kernel/debug/tracing/set_event

As described here [1], I expect that dmesg shows me some traces but there
aren't any. My dmesg logs are empty(just the same as with not having
enabled the events).

What could I be missing? Am I checking the wrong place for the trace? Are
there no tracepoints getting hit?

Any hits and pointers would be much appreciated.

Regards,
David
