Message-ID: <20240130013549.89538-2-sj@kernel.org> (raw)
In-Reply-To: <20240130013549.89538-1-sj@kernel.org>
DAMON tracepoints example on the DAMON usage document is using DAMON

sysfs interface.

While the monitoring is turned on, you could record the tracepoint events and
show results using tracepoint supporting tools like ``perf``. For example::
- # echo on > monitor_on
+ # echo on > kdamonds/0/state
# perf record -e damon:damon_aggregated &
# sleep 5
# kill 9 $(pidof perf)
- # echo off > monitor_on
