Cool! Thanks!
Just a couple of minor suggestions from my side.
Allow to change log level dynamically which is handy for debugging problems. Set loglevel to debug: sudo kill -s SIGRTMIN+20 $(pidof tetragon) time="2023-06-02T12:59:43+02:00" level=info msg="Listening for events..." time="2023-06-02T12:59:47+02:00" level=info msg="Received signal SIGRTMIN+20: switching from LogLevel 'info' to 'debug'" time="2023-06-02T12:59:57+02:00" level=info msg="Received signal SIGRTMIN+20: LogLevel is already 'debug'" Sending the second signal shows up that the loglevel is already debug.

Set loglevel to trace level: sudo kill -s SIGRTMIN+21 $(pidof tetragon) time="2023-06-02T13:07:17+02:00" level=info msg="Listening for events..." time="2023-06-02T13:07:28+02:00" level=info msg="Received signal SIGRTMIN+21: switching from LogLevel 'debug' to 'trace'" Signed-off-by: Djalal Harouni <tixxdz@gmail.com>

Allow to reset original log level by sending SIGRTMIN+22 signal to tetragon. sudo kill -s SIGRTMIN+20 $(pidof tetragon) sudo kill -s SIGRTMIN+21 $(pidof tetragon) sudo kill -s SIGRTMIN+22 $(pidof tetragon) sudo kill -s SIGRTMIN+22 $(pidof tetragon) output: time="2023-06-02T13:14:31+02:00" level=info msg="Listening for events..." time="2023-06-02T13:14:33+02:00" level=info msg="Received signal SIGRTMIN+20: switching from LogLevel 'info' to 'debug'" time="2023-06-02T13:14:37+02:00" level=info msg="Received signal SIGRTMIN+21: switching from LogLevel 'debug' to 'trace'" time="2023-06-02T13:14:40+02:00" level=trace msg="process_exec: no container ID due to cgroup name not being a compatible ID, ignoring." cgroup.id=13750 cgroup.name=vte-spawn-5c6c92b1-0631-48d7-855c-bc00f4b70255.scope process.binary=/usr/bin/pidof process.exec_id="OjE2MDExMDU5NDY0NzgxOjEzODMzOQ==" time="2023-06-02T13:14:40+02:00" level=trace msg="process_exec: no container ID due to cgroup name not being a compatible ID, ignoring." cgroup.id=13750 cgroup.name=vte-spawn-5c6c92b1-0631-48d7-855c-bc00f4b70255.scope process.binary=/usr/bin/sudo process.exec_id="OjE2MDExMDgxNzM4MTE2OjEzODM0MA==" time="2023-06-02T13:14:40+02:00" level=trace msg="process_exec: no container ID due to cgroup name not being a compatible ID, ignoring." cgroup.id=13750 cgroup.name=vte-spawn-5c6c92b1-0631-48d7-855c-bc00f4b70255.scope process.binary=/usr/bin/kill process.exec_id="OjE2MDExMTAxMjU2NTU4OjEzODM0Mg==" time="2023-06-02T13:14:40+02:00" level=info msg="Received signal SIGRTMIN+22: resetting original LogLevel 'info'" time="2023-06-02T13:14:42+02:00" level=info msg="Received signal SIGRTMIN+22: resetting original LogLevel 'info'" Signed-off-by: Djalal Harouni <tixxdz@gmail.com>
