system syslog question

Hello,
I am doing an icmp request passing through vyos and I would like to see what is happening in vyos in syslog.
I set the following syslog configuration:
vyos@vyos# show system syslog
global {
facility all {
level debug
}
}

[edit]

But i don’t see any trace related to my traffic. How should I configure the log?

Thanks and BR/

You should enable some firewall on the interface you want to see syslog traffic and configure the firewall rule to log packets passing the rule (or enable default logging on the firewall rule-set).

Is this also the way to check in syslog if vyos is dropping a packet?

Thanks and BR/

Yes
