My fail2ban log file will show information about jail starting and stopping upon restart of the fail2ban service, but if an IP is being blocked by fail2ban, this is NOT reflected in the log.

I tested this with ftp, where I run vsftp on the server, and I try to log in several times with wrong password, fail2ban successfully bans the ip for the correct time, then unban it. but nothing is shown in the fail2ban logs, and I also do not get any email.

has anyone seen this before? is there a config setting where I can force this to be logged?
